'''''Halo Wars''''' is the first real-time strategy game in the [[Halo Universe|''Halo'' Universe]]. It begins in the year [[2531]], 21 years prior to ''[[Halo: Combat Evolved]]'', during the [[Covenant Empire|Covenant]] eradication of the Outer Colonies in the [[Human-Covenant War]]. The game was developed by [[Ensemble Studios]], and is an Xbox 360 exclusive, like ''[[Halo 3]]''. Unlike other ''Halo'' games, ''Halo Wars'' is rated "T" for Teen, downgraded from "M" for Mature given to previous installments. In the U.K, the game is a 16+ game, while its predecessor ''Halo 3'' is a 15+ game although this is due to the two games using different rating boards (PEGI is stricter than the BBFC). Downloadable content and support is currently being developed by [[Robot Entertainment]], a studio founded by ex-Ensemble Studios employees after its closing.<ref>[http://www.robotentertainment.com/PressRelease.htm]</ref>

As of February 28th, 2010 (or March 1st, 2010)<ref>[http://www.halowars.com Halo Waypoint and Halo Wars]</ref>, Halo Wars and HaloWars.com support was transferred from Robot Entertainment to [[Halo Waypoint]], it was stated that Waypoint would provide "exciting plans", but this has yet to come to fruition <ref>[http://www.halowars.com Halo Wars en route to Waypoint]</ref>.

In the RTS game '''''Halo Wars''''', players can command armies of both old and new [[UNSC]] units during its first encounters against the Covenant, a massive collection of alien races that threatens to destroy all of humanity. ''Halo Wars'' will immerse gamers in an early period of the ''Halo'' Universe, allowing them to experience events 21 years prior to ''[[Halo: Combat Evolved]]''.

With the guidance of the [[A.I.]] [[Serina]], from the UNSC CFV-88 ''Spirit of Fire'', the player leads UNSC soldiers and vehicles against classic Covenant foes, such as [[Grunts]], [[Elites]], [[Ghosts]], and [[Banshees]]. Each group has its own strengths and abilities in battle. Strategic-minded players who react well under pressure will emerge victorious over their foes.

''Halo Wars'' can be played in both single-player and online cooperative campaign modes. Additionally, up to six players can play three-versus-three match head-to-head over [[Xbox Live]]. Published by [[Microsoft Game Studios]], ''Halo Wars'' is a title exclusive to the [[Xbox 360]]. Despite speculation of a version for the PC, [[Ensemble]] and [[Microsoft]] have repeatedly said that no such plans have been made or even considered. The Covenant is playable only in [[multiplayer]] and [[Skirmish]] modes.

Ensemble Studios began recording the music for the game in March 2008, with Ensemble's Music and Sound Director, Stephen Rippy, flying to Prague for the orchestral and choral parts and to Seattle for the piano and mixing.<ref>[http://www.halowars.com/news/articles/archive/2008/03/27/Halo-Wars-Monthly-Update-03.27.08.aspx ''Halo Wars'' Monthly Update 03/27/08]</ref><ref>[http://forums.halo.fr/viewtopic.php?p=315181 Interview-Graeme Divine].</ref><ref name="xbox360fanboy.com">http://www.xbox360fanboy.com/2008/04/18/halo-wars-alpha-spotted-on-xbox-live/</ref>

===Plot===

[[File:Harvest Plasma Glassed.jpg|thumb|left|Harvest, just after the UNSC ''Spirit of Fire'' arrived in the system.]]

The game's story is told through in-game cut scenes and in-game moments, as with the other ''Halo'' games. The game is set in 2531<ref>http://www.computerandvideogames.com/article.php?id=168577</ref> and focuses around the [[UNSC Marine Corps|Marine]] forces of the [[UNSC Spirit of Fire|UNSC ''Spirit of Fire'']] as they engage Covenant ground forces after the discovery of an ancient artifact during a journey to the partially [[glassed]] [[Harvest]].

The story begins with the UNSC's early battles on Harvest, but also features another colony world, [[Arcadia]], which holds "something of great interest to the Covenant". The planet is subsequently invaded by the Covenant and the UNSC must evacuate the planet while engaging the invasion force. The [[Flood]] is significant in the storyline and several massive [[Forerunner]] structures are also explored.

This game differs from previous ''Halo'' titles in that [[Master Chief]] does not make any appearance, although several key SPARTANs, collectively known as [[Red Team]], do factor into the plot. In contrast, the ''Spirit of Fire'' is "full of new characters", such as the A.I. Serina, [[Ellen Anders|Professor Ellen Anders]], [[Sergeant]] [[John Forge]], and the ''Spirit of Fire'''s commander, [[Cutter|Captain Cutter]].<ref>[http://forums.halo.fr/viewtopic.php?p=315181 Interview-Graeme Devine]</ref> Some of these characters go planetside to aid the player. The single player campaign is purely from the UNSC's perspective.

While Sergeant Forge is patrolling the northern regions, [[Alpha Base (Harvest)|Alpha Base]] was attacked and destroyed by the Covenant, with survivors fleeing to the countryside surrounding the area. Rounding up these survivors, Forge leads them in an assault that removed the Covenant presence and reestablished Alpha Base, returning it to operational status.<ref>''Halo Wars'', "[[Alpha Base (Level)|Alpha Base]]"</ref> Forge leads an assault on the [[Relic (Structure)|relic site]] itself, removing the Covenant occupiers and preventing the enemy from destroying it to deny human access, and securing the site for Anders to examine it briefly before a Covenant counter-attack cuts them off from Alpha Base.<ref>''Halo Wars'', "[[Relic Approach (Level)|Relic Approach]]"</ref> [[Grizzly]] tanks launched from the ''Spirit of Fire'' manage to cut through the Covenant, linking up with Forge and his Marines, and escorting them back out through the relic while forces from Alpha Base held off the Covenant. Information gathered from the Harvest relic shows that the Covenant have been pointed to a second UNSC colony, Arcadia.<ref>''Halo Wars'', "[[Relic Interior (Level)|Relic Interior]]"</ref>

Following the Covenant to Arcadia, they find that the most of the orbital defense ships have been either destroyed or damaged in battle with the Covenant (one of the many ships is the [[UNSC Pillar of Autumn|''Pillar of Autumn'']] which would be involved in the "Halo incident" twenty years later). Sgt. Forge and his forces deploy on the ground in order to assist the SPARTANs from [[Red Team]] in the effort to evacuate civilians from Arcadia City, via cargo transports.<ref>''Halo Wars'', [[Arcadia City (Level)]]''</ref> Afterward, the UNSC forces withdraw to a defensible area on the city outskirts, holding off Covenant attacks long enough for [[SPARTAN Group Omega]] to arrive and assist in the destruction of local Covenant forces.<ref>''Halo Wars'', "[[Arcadia Outskirts (Level)|Arcadia Outskirts]]"</ref> At the same time, the Covenant have erected a large energy shield generator around a site of importance, with [[Arcadia Forerunner Ruins|undiscovered ruins]] surrounding the area, forcing the UNSC to deploy prototype [[Rhino]] plasma artillery to penetrate it.<ref>''Halo Wars'', "[[Dome of Light (Level)|Dome of Light]]"</ref> Moving in to examine what was of such interest to the Covenant, they come under attack from a Super Scarab, only partially complete and annihilating any UNSC forces in its line of sight. Eventually managing to destroy it, Anders and Forge begin documenting the area, only for the [[Arbiter (Halo Wars)|Arbiter]] to arrive, taking Anders prisoner and wounding Sergeant Forge, with Red Team arriving too late to assist.<ref>''Halo Wars'', [[Scarab (Level)]]</ref> Rapidly heading out of the system aboard a starship, the ''Spirit of Fire'' follows, eventually emerging in orbit over a [[Shield World (Halo Wars)|mysterious planet]] in an unknown location.

Deploying ground forces to search for Anders, the UNSC and Covenant forces come under attack from a previously undiscovered alien organism - the Flood.<ref>''Halo Wars'', [[Ander's Signal (Level)]]</ref> Managing to regroup and hold a defensible location, the UNSC forces manage to locate the source of the signal - an apparent body of water.<ref>''Halo Wars'', [[The Flood (Level)]]</ref> The UNSC forces withdraw back to the ''Spirit of Fire'' as a concentrated Flood force begins to gather momentum, narrowly escaping annihilation, regrouping at the ''Spirit of Fire'' over the lake - which splits to reveal an entrance, and with swarms of [[Sentinels]] emerging to deal with the Flood.<ref>''Halo Wars'', [[Shield World (Level)]]</ref> The ''Spirit of Fire'' manages to enter, proceeding through a docking system, removing Flood growths and moving through a system of concentric rings that filters out Flood biomass<ref>''Halo Wars'', [[Cleansing (Level)]]</ref>, the ''Spirit of Fire'' emerges inside a massive [[Shield World]], immediately engaging a [[Covenant Destroyer]] and fending off attacks while conducting repairs.<ref>''Halo Wars'', [[Repairs (Level)]]</ref>

The Arbiter uses Anders to activate [[The Apex]], revealing a fleet of Forerunner warships which the Covenant plans on reverse-engineering and incorporating into their existing naval forces to crush the humans quickly, without needing to dedicate all of their existing forces to the war. Anders manages to escape, using what had been her stasis prison as a translocation device, teleporting to the surface of the Shield World's interior, linking up with Forge and his Marines, who clear the area of Covenant forces and establish a base of operations on the Shield World.<ref>''Halo Wars'', [[Beachhead (Halo Wars Level)|Beachhead]]</ref> Removing the ''Spirit of Fire'''s FTL Reactor, the UNSC move it into The Apex, planning to detonate it - the chain-reaction will send the Shield World's sun into a supernova, destroying the installation and the fleet, denying it to the Covenant and saving humanity from near total defeat and extinction. The Arbiter attempts to stop them, but his [[Honor Guards]] are killed by Red Team, and Forge himself manages to kill the Arbiter with one of his own Energy Swords.<ref>''Halo Wars'', [[Reactor (Level)]]</ref> Forge stays behind to detonate the reactor, while the rest of the UNSC forces activate a portal out of the Shield World, evacuate to the ''Spirit of Fire'', and manage to slingshot around the sun to build up enough speed to escape the supernova's blast radius and the range of the Shield World's debris.<ref>''Halo Wars'', [[Escape (Level)]]</ref>

Now unable to return to UNSC space with the speed an FTL drive would have afforded them, the ''Spirit of Fire'''s crew enter cryonics storage. The ship begins its long journey home, likely to take many years or decades. Here, Sgt. Forge's cyro tube is closed by Captain Cutter, who briefly nods, upon which the camera pans down to find the words "Sgt. J. Forge", acknowledging the sacrifice of the valiant Marine [[Sergeant]].

In the final moments of the credits, Serina speaks the final words of the game, saying "Captain. Wake up. Something has happened," As the logo appears on the screen.

The ultimate fate of the ''Spirit of Fire'' is unknown. Investigations by the UNSC and ONI are officially closed a few years after it is officially designated MIA, but there is some evidence that the ship does at some point return to UNSC space, with the strongest argument being the number of Spartans present during the [[Fall of Reach]]; At the time, 25 of the remaining 28 are present on the planet, with the three missing identified as [[Grey Team]] and the remaining dead or missing all previously identified, leading credence to the idea that Red Team, do eventually reunite with the UNSC. However it is noted that since ''Spirit of Fire'''s crew were the first humans to encounter the Flood, information should have been reported to ONI, but the first recorded Human-Flood encounter was in 2552, 21 years later, on Halo Installation 04, meaning that either the ''Spirit of Fire'' did not come back or ONI kept the 2531 Human-Flood encounter a closely guarded secret.

*[[SPARTAN-II]]: SPARTAN-IIs are individually trained units who are arguably superior to all UNSC and Covenant infantry types. SPARTANs are equipped with a regenerating shield in addition to a health bar. They begin with dual-wielded [[M7/Caseless Submachine Gun|SMGs]] and can hijack all enemy vehicles except the [[Scarab]] and [[Vulture]] gunship for balance purposes, bringing them under player control; they can also commandeer allied vehicles. They can be upgraded to wield [[AIE-486H Heavy Machine Gun|chain guns]] and [[Spartan Lasers]], as well as neural implants, which help them hijack vehicles much more quickly.<ref name = "IGN E3 2008: ''Halo Wars'' Hands-on">[http://au.xbox360.ign.com/articles/890/890357p1.html E3 2008: ''Halo Wars'' Hands-on]. ''Alex Simmons''. Accessed on 2008-17-07</ref> When a SPARTAN takes control of an allied or enemy vehicle, the Spartan's rank is added to the vehicle's rank and the vehicle's stats are greatly increased. Spartans can also engage in hand-to-hand combat against certain enemies ([[Elite Honor Guards]], [[Infection Forms]], etc). Only three SPARTANs can be deployed at a time and do not contribute to the player's population limit. They are outfitted with the [[MJOLNIR Mk. IV]]; the in-game units posses traits that are trademarks of the Mk. V armor, however, this is for gameplay considerations and is not accepted as canon.  

*[[Hellbringers]]<ref name="Forum">http://www.halowars.com/forums/thread/242938.aspx</ref>: Also known as "Flamethrower units", these Marines are specialists equipped with heavier armor and flame-throwers that can be used to torch entire infantry units. They can be upgraded with flash bang grenades, which stun enemies when hit, napalm ammunition, which allows their attacks to burn slightly afterward, and oxide tanks, which also increase damage. They are incapable of attacking air units, obviously because of their shorter hit&nbsp;range.&nbsp;They can run somewhat faster than standard Marines.<ref name = "IGN E3 2008: ''Halo Wars'' Hands-on"/>

*[[UNSC Marine Corps|UNSC Marines]]: Marines are the basic infantry of the UNSC who are armed with [[MA5 Series]] rifles and have the special ability to throw [[M9 High-Explosive Dual-Purpose Grenade|grenades]].<ref name = "CES 09">[http://www.g4tv.com/ces2009/hdvideos/36151/Halo-Wars-CES-09-Cam-Footage.html ''Halo Wars'' CES 09 Cam Footage]. ''G4''. Accessed on 2009-01-20</ref> The squads can be upgraded to replace their [[grenades]] with [[rocket launcher]]s (called RPGs in-game), making them more effective against vehicles and giving them superior attack power against air units.<ref name = "IGN E3 2008: ''Halo Wars'' Hands-on"/> They usually operate in squads of four but may add another member to their squads via the "[[New Blood]]" upgrade<ref name = "CES 09"/>, and a [[medic]] via the [[medic upgrade]], adding up to a total of six squad members. However, the medic can only heal existing squad members, and cannot resurrect fallen squad mates.

*[[Orbital Drop Shock Troopers]]: Also known as "Helljumpers", in reference to the heat of the HEV pods they use to descend from orbit, this is an available upgrade for marine squads. It can be upgraded at the [[Barracks]].<ref name = "OXM">January 2009, ''Official Xbox Magazine'', pp 38-43</ref> The upgrades effects allow the player to substitute standard marine squads with ODST teams (armed with M90 shotguns), as well as the HEV drop. The HEV drops can also be used as a weapon similar to the MAC Blast and also like the MAC blast&nbsp; the ability to drop has to be used in a visible area. To do so, the player must select the HEV drop ability and put them over the area that they wish to drop them in. ODST squads still possess the rocket launcher ability that is previously upgraded for the marine squads. They are only available as the special upgrade for Captain Cutter. Effects include increased line of sight and more hitpoints.

*[[Warthog|M12 Light Reconnaissance Vehicle]] (Warthog): Can jump gaps, and has a ramming ability as its special attack. May be upgraded so its passenger has a grenade launcher. Ramming ability is strong enough to destroy a Ghost.<ref name = "CES 09">[http://www.g4tv.com/ces2009/hdvideos/36151/Halo-Wars-CES-09-Cam-Footage.html Halo Wars CES 09 Cam Footage]. ''G4''. Accessed on 2009-01-20</ref> Warthogs can collect resources from crates found on the battlefield.

**Upgrade 1: The Warthog gains a marine mounted on the [[M41 LAAG]] turret.

**Upgrade 2: The Warthog gains a Marine armed with a Grenade launcher.

*[[M808 Scorpion MBT]]: The M808 Scorpion is the basic UNSC tank. It can be upgraded to the "[[Grizzly]]" variant.

**Upgrade 1: The Scorpion gains the "canister shell" secondary ability which is superior against infantry.

**[[Grizzly|Grizzly variant]]<ref name=Forum/>: An upgrade of the Scorpion, it possesses two cannons and a machine gun. This upgrade is only available when the player chooses [[Sergeant Forge]] as his or her [[Hero Units|hero unit]] in [[Skirmish|Skirmish mode]] or [[multiplayer]].

*[[Behemoth-class Troop Transport|''Behemoth''-class Troop Transport]]<ref name=Forum/> (Elephant): The Elephant, as it is more commonly known, can carry squads into combat and can fulfill the role of a barracks in the field, along with having the ability to be upgraded with a cannon (though only if deployed), twin engines to upgrade speed, and ceramic armor to allow the Elephant to take more damage. During the campaign, it is used to tow the ''Spirit of Fire'''s [[Shaw-Fujikawa Translight Engine]] up a mountain to the Apex. During multiplayer and skirmish, it is [[Captain Cutter]]'s unique unit. Note that the dialogue of the Elephant is drastically reduced after the "Defense Turret" upgrade is unlocked.

*[[Gremlin Combat Support Vehicle|Gremlin]]: A combat support vehicle, the Gremlin is [[Professor Anders]]'s unique unit. It attacks with an EMP cannon that disables vehicles or non-infantry units temporarily. It can be upgraded to fire farther and hit harder and to make the EMP blast chain through multiple vehicles. The Gremlin has absolutely no combat efficiency against air units. Gremlins cannot do very much damage to infantry.

*[[Rhino]]: The Rhino is a heavy tracked unit that has a greater defense but lower attack than the Scorpion. The Rhino is armed with a heavy prototype plasma cannon stolen from the Covenant that fires giant plasma bolts. The Rhino is only in the campaign and not available in Skirmish. It is incapable of attacking air units. During the campaign, it is used during [[Dome of Light]] to break through a Covenant energy shield on [[Arcadia]].

*[[Wolverine]]: The Wolverine is a specialized anti-aircraft vehicle that uses guided missiles to shoot down enemy aircraft, such as [[Banshees]] or [[Vampires]]. While powerful in this aspect, it is especially weak against infantry and anti-armor vehicles, and must be heavily protected. It can be upgraded with a volley ability to unleash a fusillade against buildings. It can also be upgraded to use Dual Launchers, increasing the number of missles it fires, increasing its damage.

*[[Cobra]]<ref name=Forum/>: The Cobra is a heavy anti-armor vehicle armed with a pair of rail cannons which can easily tear apart enemy armor. It can be outfitted with stronger armor when locked down and its rail cannons can be upgraded to penetrate multiple enemies. Its special ability allows it to lock down for greater range, at the expense of mobility. Cobras cannot attack aerial units.<ref>[http://www.halowars.com/GameInfo/vehicledepot.aspx#Cobra]</ref>

*[[Cyclops|Cyclops Exoskeleton]]<ref name=Forum/>: The Cyclops is a re-appropriated support exoskeleton that can crush ground enemies in close combat, often finishing off infantry with impressive fatality moves. It can also repair damaged vehicles and buildings if the player upgrades it once. A second upgrade of the unit improves speed. It can also throw debris at enemy units as its special attack. (Unique to [[Sergeant Forge]])

*[[Dropship 77-Troop Carrier|D77-TC Pelican Dropship]]: The Pelican is used via a UNSC ability that is called from the ''Spirit of Fire'' menu. The pickup area is selected, then the drop-off area. The Pelican can transport multiple units at one time. A single Pelican drop can airlift 6 infantry squads and three vehicles. It cannot carry Elephants. If it is destroyed, all units being carried by it are lost as well.

*[[Shortsword-class Bomber|''Shortsword''-class Bomber]]: Shortsword bombers perform low-altitude bombing runs for support on the battlefield.

*[[Hornet]]<ref name=Forum/>: The Hornet is a light gunship that can carry two passengers to provide support and fire on enemy ground and air targets. If upgraded once ("Wingmen" upgrade) two Marines equipped with rocket launchers ride on the Hornet for increased damage. A second passive upgrade ("Chaff Pods") allows for better avoidance of missile attacks.

**[[Hawk]]: The Hawk is a further upgraded version of the Hornet that is equipped with a mounted [[laser]] for large damage. The dual autoguns have a slower rate of fire but sport increased damage per shot. (Unique to [[Professor Anders]])

*[[Vulture]]: The Vulture is a large gunship that can deliver heavy amounts of fire against all targets. It can be upgraded once to double the number of missiles to eight in its special attack "barrage", which previously carries four. It is the UNSC "Über-unit", and though it is nowhere near as strong or resilient as the Scarab, it makes up for this deficiency by being less than a third of the cost of a Scarab in both population and supplies.

*[[Pod]]: This dropship, larger than both the Pelican and Vulture, delivers extremely large objects, such as portions of [[Firebase]]s, to ground positions.

**[[Field Armory]]: A combination of machine shop and laboratory that provides high-tech upgrades for the UNSC.

**[[UNSC Barracks]]: The barracks can provide a number of infantry types for combat and to upgrade.

**[[UNSC Supply Pad]]: Supply Pads are used to get supplies from the ''Spirit of Fire'' via Albatross dropships. Can also be upgraded to Heavy Supply Pads to double the rate of resupply.

**[[Base Turret]]: Initially armed with an [[M202 XP Machine Gun]]. The turret may be outfitted with a rail cannon for use against vehicles, a flame mortar for use against infantry, or a missile launcher for use against aircraft. Only available on "Station/Fortress" Command bases.<ref>[http://www.halowars.com/GameInfo/firebase.aspx#Turret]</ref> They can be upgraded to Medium Turrets and Large Turrets at the [[Field Armory]].

*[[Unggoy]] (Grunts): Fight in lances consisting of a [[Minor Elite]] (or, depending on the player's selected leader, a [[Minor Brute]]) and several Grunts. They have the secondary ability to throw plasma grenades and can be upgraded with needlers, additional members, and a [[Deacon]] to boost combat capabilities through spirituality.<ref>http://halowars.com/images/cov/covenant_grunt_squad.jpg</ref>

**[[Unggoy#Overall in Combat##Suicide Grunt|Suicide Unggoy]] (Suicide Grunts): Will berserk and blow themselves up on command. Leader-specific unit of the Arbiter. The explosion is very effective against buildings. They can be upgraded to receive more speed in suicide mode as well as to amplify damage to their suicide attack through the use of deadly adherents.

**Bomber Unggoy: A grunt that carries an explosive that can eliminate an entire infantry squad. They only appear in Campaign.

*[[Sangheili]] (Elites): In addition to leading Unggoy lances, Elites serve many other roles, such as drivers of vehicles and pilots of aircraft.

**[[Honor Guard Elite|Honor Guard Sangheili]]: Honor Guards serve as powerful anti-infantry units, or more rather, a close combat substitute for Jackals. They can be upgraded with energy shields which notably increase survivability, and active camouflage and are the leader-specific unit of the [[Prophet of Regret]].

**[[Ripa 'Moramee]]: An antagonist in the campaign and a leader unit in multiplayer. The Arbiter starts with dual energy swords and rage special attack that drains resources but makes 'Moramee go on a "killing spree". Upgrades for rage mode include restored health with every kill, cheaper cost to maintain rage, and an increased damage bonus for all friendly nearby units. 'Moramee can also upgrade his armor to reflect some damage back to the attacker, increase damage, and to incorporate permanent active camouflage. Ripa 'Moramee will face extreme difficulty against sentinels, even in rage mode. Counter this weakness with any unit that can attack air units or with the Arbiter "Fiendish Return" upgrade.

**Needler Elites: A pair of Elites that wield [[Needler]]s and have an [[Energy Shield|energy shield]]. They cannot be trained in skirmish mode even if a Covenant leader is played, and are exclusive to campaign mode.

*[[Mgalekgolo]] (Hunters): Hunters are heavily armored and armed with fuel rod-launching assault cannons, like they are in ''Halo: Combat Evolved''. They are the Covenant's primary anti-vehicle infantry. When upgraded, they can receive their traditional shield, a "Spirit Bond" to increase damage given that both of the initial Hunters are alive (this means resurrected Hunters do not receive the Spirit Bond upgrade), and later they can fire a more powerful beam from their cannons.

*[[Kig-Yar]] (Jackals): Jackals fight in pairs in ''Halo Wars'' and provide good defense against Marines armed with conventional weapons but little defense against grenades, explosives or vehicles. They are originally armed with carbines without shields but can be upgraded to incorporate point defense gauntlets, beam rifles, and eventually stronger gauntlets in the later stages of the Covenant tech tree.

*[[Jiralhanae]] (Brutes): In battle the Brutes wield Brute shots, which are devastating against infantry and effective against light vehicles. Due to their limited battlefield use prior to the events of ''[[Halo 2]]'', they are apparently leader-specific units belonging to the unknown [[Brute Army Commander|Chieftain]]. They can be upgraded to have [[Jump Pack Brute|Jump packs]] and install EMP grenades in their brute shots.<ref name="xbox.com">http://www.xbox.com/NR/rdonlyres/31804095-7B32-4CE2-A17E-3CB54A3692EF/0/HaloWars_MNL_EN.PDF</ref>

**[[Brute Chieftain|Jiralhanae Chieftain]]. The only usable Brute Chieftain is the same Chieftain that can be selected as a leader, making him a "hero" unit for the faction like the Arbiter.<ref name="xbox.com"/>

*[[San 'Shyuum]] (Prophets): Prophets fight from their [[Gravity Thrones]] and can attack enemy infantry with their destructive plasma weapons. The only usable in-game Prophet is the [[Prophet of Regret]], who can only be used if he is chosen as a "leader" before the start of the game.<ref name="xbox.com"/> The Prophet's plasma cannons can be upgraded to fuel rod cannons for increased damage. His second upgrade adds a pair of Offensive Protectors to protect him and his final upgrade gives him full flight capabilities. His leader power is called "Cleansing", where an energy projector's beam is called down from an orbiting warship to quickly incinerate anything beneath it. The glassing beam can be upgraded to deal more damage.

**[[Protector Sentinel|Protectors]] - A pair of Sentinel-like Protectors guard the Prophet of Regret after the player researches "Ancestral Perversion".

*[[Type-47 Ultra Heavy Assault Platform]] (Scarab): The Scarab is a super-unit that can destroy infantry, ground vehicles, and aircraft with ease. The Scarab is extremely resilient to most weapons fire. Both the ''Halo 2'' and ''Halo 3'' versions have been seen, though the ''Halo 2'' era Scarab has not appeared in more recent ''Halo Wars'' videos and demos. Spartans are unable to hijack Scarabs, with the exception of one campaign level in which the Covenant abandon a scarab and you have a choice to get it. The Scarab is unique in its ability to traverse what is considered "rough terrain". In other words, the Scarab can climb over cliffs, mountains, and some structures because of its size and structuring. This makes it the only playable ground unit in the game able to do so.<ref name="gametrailers.com">http://www.gametrailers.com/player/41104.html</ref>

*[[Super Scarab]]: Seen in the 7th campaign level and is larger and more powerful than a normal scarab. It's legs aren't built yet and cannot be used, but relies on power generators scattered throughout the map for energy to turn its head. Despite the vulnerability of its power source, it is still a very dangerous threat capable of incinerating anything in moments.

*[[Type-32 Rapid Assault Vehicle]] (Ghost): The Ghost is a light attack vehicle that excels against infantry but not other vehicles. Can be upgraded to have a ramming boost ability, similar to the Warthog's Ram ability. Can also be upgraded to strafe as to avoid incoming grenades and rockets and to have a light energy shield.

*[[Type-25 Rapid Assault Vehicle]] (Chopper): The Chopper is a scout-class vehicle available only to the Brute Chieftain leader. The Chopper starts without any guns and is only able to ram hostile ground targets. The Chopper can then be upgraded to include dual cannons on the sides of the Chopper to give the Chopper combat capability and additional ramming targets to increase ramming damage and decrease feedback damage (the damage the Chopper takes after ramming). The autocannons can also be upgraded to equip stabilizers, improving autocannon accuracy and damage.<ref>http://au.xbox360.ign.com/dor/objects/857436/halo-wars/images/halo-wars-20081113023451375.html</ref>

*[[Type-25 Assault Gun Carriage]] (Wraith): The Wraith is the main battle tank of the Covenant and is armed with a plasma mortar and a plasma turret capable of decimating enemy infantry and vehicles. It can also be upgraded to allow for the "Scorch" special ability, as well as to have an energy shield. The mortar can also be upgraded to receive a large overall damage boost.

**[[Honor Guard Wraith]]: This unique looking type of Wraith is only available by activating a skull exclusive to the special edition, which also requires Xbox live to obtain.

*[[Locust]]: A smaller counterpart to the Covenant [[Scarab]] which is described as a "building-killer". When upgraded with the overdrive ability, the Locust can drain its shields for extra power by using the secondary attack button. Another upgrade for the Locust allows its shield to regenerate faster, which can be bolstered by the "Forerunner Shield" upgrade to compound the recharge speed.

====Aerial====

*[[Type-26 Ground Support Aircraft]], otherwise known as the [[Banshee]]: The [[Banshee]] can attack infantry, tanks and other air vehicles due to its twin Plasma Cannons and single Fuel Rod Cannon. With upgrades, Banshees' rate of fire on their Plasma Cannons is increased and Banshees can attempt to crash into enemy units or buildings when they are shot down, causing extra damage. Banshees also have the ability to boost after the 1st upgrade.

*[[Type-25 Troop Carrier|Type-25 Troop Carrier Spirit]]: The Spirit is the rival to the UNSC Pelican, capable of carrying vehicles and infantry in addition to giving them fire support. The screen for the Spirit of Fire is not available for the Covenant Leaders and therefore these cannot be called upon to transport troops or vehicles in skirmish or multiplayer modes.

*[[Vampire]]: A Covenant flying vehicle; a potent craft fitted to fight against hostile air vehicles. It can be upgraded to have a stasis beam that drains enemy aircraft health and replenishes its own, and later they can create an explosion after stasis if fully upgraded. It should be accompanied by Banshees to defend from ground units.

*[[Huragok]] (Engineers): Sent into combat zones to repair damaged vehicles and structures, as well as squads of infantry. The upgrade, State of Grace, will increase its repair rate while the upgrade, Harmonious Digestion, will increase its speed. An Engineer may repair other Engineers, but not itself.<ref>http://www.halowars.com/GameInfo/Covenant.aspx</ref>

====Buildings====

*[[Outpost]]/[[Keep (Covenant)|Keep]]/[[Citadel (Covenant)|Citadel]]: Provides the basic base of the Covenant with optional 'add on' buildings that can increase its usefulness. Outpost can be upgraded to Keep and then to a Citadel.

**[[Shield Generator (Covenant)|Shield Generator]]: Provides shield protection for the whole Citadel. It is possible to have multiple shield generators, thus improving the Citadel's shielding.

**[[Warehouse (Covenant)|Warehouse]]: The warehouse is how the Covenant receive supplies. Gravity lifts bring supplies down and workers move them to their proper area. The warehouse can be upgraded to a blessed warehouse, which will receive supplies more often.

**[[Heavy Plasma Turret]]: The main defenses of a Covenant base, the Turret first starts with Plasma Turrets, but can be upgraded with a Plasma Mortar, [[Fuel Rod Cannon]], or a [[Heavy Needler]].

**[[Temple (Covenant)|Temple]]: A Covenant research building, the upgrades are very expensive but are very effective and powerful.

**[[Summit (Covenant)|Summit]]: The roost of the Covenant air force, the Summit builds Banshees, Vampires and Engineers.

**[[Hall (Covenant)|Hall]]: The home of Covenant soldiers, Grunt lances, Jackal pairs and Hunter pairs are trained here. The building also researches minor upgrades for Covenant infantry.

**[[Factory (Covenant)|Factory]]: The manufacturing plant of the Covenant, the Factory builds Ghost scouts, Wraith tanks and Locust walkers.

*[[Anti-Vehicle Barrier]]: Same device used to block tunnels on the level [[Tsavo Highway]] in ''Halo 3'', most likely used for defense. To be used, infantry needs to go on it like a [[Deployable Lookout Tower|Lookout Tower]]. It is both availiable in campaign and certain maps in multiplayer<ref>http://xbox360.gamespy.com/dor/objects/857436/halo-wars/images/halo-wars-20081009024128843.html</ref>

*[[Type-26 ASG]] (Shade): The ''[[Halo: Combat Evolved]]'' variant of the Shade is featured as a defensive Structure. This is only available in Campaign.<ref>http://www.mondoxbox.com/immagini.php?game=1128&view=1&start=9#topnav</ref>

*[[Deployable Lookout Tower]]: Can be used to garrison infantry units from both players (in co-op), increasing their combat capabilities.

*[[Mega Turret]]: A massive turret featured in campaign where the Mega Turret looks like a upgraded version for the Heavy Turret. It's power is very high and it is advisable to take it out with the MAC Blast. It is also featured as a neutral garrison able structure on [[Tundra]]. Here it fires in barrages and takes time to recharge. It is indestructible (but as always, the garrisoned troops can be killed).

*[[Gravity Lift]]: Each Covenant base has a [[Gravity Lift]] right outside. Gravity Lifts let the Covenant's players to do "Hot Dropping" which allows to send any units (except the Scarab) directly to their Leader's location.<ref>[http://www.1up.com/do/previewPage?pager.offset=1&cId=3172311&p= 1]</ref>

====Ship Support====

*[[Glassing]]: This appears to be used as a Covenant super weapon. The glassing ship can fire this from orbit to destroy ground positions and units. Can be upgraded for an even more devastating effect. This is named the "[[Cleansing Beam]]" in the game and is the [[Prophet of Regret]]'s leader power.

*MAC Rounds: These explosive rounds are fired from an orbiting ship onto the target in the designated area you choose.The orbiting ship (''Spirit Of Fire'') can fire MAC rounds to decimate Ground positions and units alike. This can be upgraded to have even more devastating power. In the game this is known as a "MAC Blast" and is Captain Cutter's leader power.

*ODST: The ODST is a super unit only available to Captain Cutter. They are more powerful than normal marines and can be droped from orbit. For more information on the ODSTs go to one of the previous articles: UNSC, Section: infantry, Unit:orbital drop shock trooper.

===Neutral Units===

====Rebels====

*[[Unnamed Harvest Rebel Group|Insurrectionist Infantry]]: Can be found occupying neutral base sites, and the area around any Forerunner structures and/or garrisonable areas that give bonuses, supply elevators, reactors, etc. They come usually armed with Assault Rifles, and in conjunction may use Rocket Launchers and snipers.

*[[Sentinel]]: Standard Sentinel, fires a standard beam, doing medium damage. Occupies Forerunner Neutral base sites and bonuses.

*[[Super Sentinel]]: Can slow down enemy units and have a more powerful sentinel beam than the standard Sentinels, cannot attack air units, rendering it harmless against air units.

*[[Protector Sentinel]]: Able to be "attached" to units, providing either a rechargeable energy shield, replenishing health, or a pulse laser weapon depending on the type of Protector. The "Ancestral Perversion" upgrade gives the Prophet of Regret two of the pulse laser types on any map.

*[[Sentinel Shop]]: Produces Sentinels for the player who stands near it. Only found on the multiplayer levels [[Repository]] and [[Glacial Ravine]].

*[[Forerunner Supply Elevator]]: Produces supplies when infantry are garrisoned inside it. Equivalent to an additional Supply Pad or Warehouse. Means you can build one less Supply Pad/Warehouse.

*[[Forerunner Spire of Healing]]: Heals any friendly units nearby for the player who controls it. Only found on multiplayer levels [[Frozen Valley]] and [[Barrens]].

*[[Forerunner Teleporter]]: Instantly sends units to another teleporter location. In most maps, these are just one way.

*[[Forerunner Bonus Reactor]]: Increases tech level of any player that controls it. This will mean you can have an extra slot on open in a base for other usage.

*[[Forerunner Lifepod|Forerunner Life Support Pod]]: Increases the max population for any player who controls it. Only found on the multiplayer level [[Beasley's Plateau]].

*[[Forerunner Fort]]: Outpost guarded by automated systems, including laser turrets and a shield wall. Retracts in on itself after sustaining enough damage.

*[[Protector Plant]]: Produces three types of Protectors for the player who stands near it. Only found on the multiplayer level [[Labyrinth]].

*[[Relic (Halo Wars)|Relic]]: Releases Flood upon an enemy when infantry are garrisoned inside it. Only found on the multiplayer level [[Release]].

[[File:Halo Wars Flood.jpg|thumb|left|Flood biomass and tentacles ensnare an [[Elephant]], with Flood [[Infection Form]]s and [[Combat Form]]s in the background.]]

{{Quote|There is quite a bit of concern regarding how we’re going to fit the [[Flood]] into our game and keep it in canon which surprised me, but I promised them all that the ''[[Halo: Combat Evolved|Halo 1]]'' canon is intact and that they would have to wait and see how we integrate the Flood.|Graeme Devine<ref>http://halowars.com/news/articles/archive/2008/10/14/Hello-from-TGS.aspx</ref>}}

The [[Flood]] are a faction within the game, though the player is unable to use them. The Flood gain units by taking over [[Human]] and Covenant troops.

In respect to keeping the appearance of the Flood in canon with the rest of the series, the game has the ''[[Spirit of Fire]]'' traveling back to Earth at speeds slower than light after its mission had ended, making it impossible for them to report the existence of the Flood. However, this raises further controversy over the presence of the Spartans on board the ''Spirit of Fire''.  

*[[Infection Form]]s have the ability to crawl over walls, increasing its potent abilities, and is able to reach ground no other forces can reach. When any infantry units encounters Infection forms, they are usually attacked and infected. This applies to all combat infantry units(except hero units such as [[John Forge]]) in the game, including both Grunts and Jackals, turning them into Combat Forms and making use of their weapons.

*[[Combat Form]]s: The standard fighting force of the [[Flood]]. There are six additional types of Combat Forms: Marine, Flamethrower, Elite, Brute, Jackal and Grunt forms in-game. Note when the infected units turn into the corresponding combat form, that unit's rank (if any) also goes with the combat form, making it more deadly.

:*[[Human Combat Form|Infected Marines]]: Marines or [[ODST]]s (and possibly Medics) that have been infected by the Flood. They come in squads of four (or, in one mission, six) when they spawn on campaign and skirmish maps, or individually when they were formerly owned by a player and then infected. They always wield [[Assault Rifle]]s and [[Shotgun]]s despite previous equipment.

:*[[Infected Flamethrowers]]: Flamethrower marines that were once owned by a player and then infected. They always wield [[Flamethrower]]s, as with living UNSC Flamethrower Marines. Infected Flamethrowers are a bit of a sub-category of Infected Marines, as they are exactly like Infected Marines but just wield Flamethrowers.

:*[[Elite Combat Form|Infected Elites]]: Elites that were infected by the Flood. They come in pairs and use a melee attack instead of weaponry when they spawn, or individually when they were formerly owned by a player and then infected. They are the only Combat Form with a Melee attack.

:*[[Brute Combat Form|Infected Brutes]]: Brutes that were infected by the Flood. They come in pairs when they spawn in campaign, or individually when they were formerly owned by a player and then infected. They always wield [[Brute Shot]]s, as with living Covenant brutes.

:*[[Flood Grunts|Infected Grunts]]: Grunts that were once owned by a player and then infected. Depending on their previous weaponry they will always wield either [[Plasma Pistol]]s or [[Needler]]s. They also retain the ability to throw plasma grenades.

:*[[Infected Jackals]]: Jackals that have been infected by the Flood. They come in pairs when they spawn on skirmish maps, or individually when they were owned by a player and then infected. They always wield [[Carbine]]s and Defense gauntlets (that can be overloaded) when infected by player controlled Jackals, despite previous weaponry, but have been encountered with [[Beam Rifle]]s when they are in scripted positions (i.e. additional reactors on flood levels).

*[[Carrier Form]]s: A suicidal unit that explodes and delivers its payload of [[Infection Forms]] directly into enemy lines.

*[[Flood Growth Pods]] now function as a double-edged sword: shooting them will sometimes releases precious resources for weapon and vehicle upgrades. At other times, however, they will release either a swarm of [[Infection Form]]s or a cloud of [[Flood spore]]s, both of which can destroy infantry squads in seconds. They appear as either large flood "eggs" the size of small vehicles, or as multiple of the ''Halo 3'' variety growing on tall stalks.

*[[Flood Thrasher Form]]s: Large, about the size of an [[Elephant]]. Essentially an anti-vehicle [[Flood]] form, although easily killed.

*[[Flood spore]] clouds: A green mist that if units are in for too long, they are killed and infected. It should be noted that these can not be killed except on occasion by [[Hellbringer|flamethrower marines]] and will decimate infantry ground forces in seconds due to their superior speed in comparison to UNSC ground units. It is also advisable to keep vehicles separate from ground infantry as the infected troop will often destroy the vehicles as they transform.

*[[Flood Swarms]]: The first-ever-seen flying incarnation of the Flood, described by developers as "infected buzzards crossed with evil bats". These creatures travel in large airborne packs, and can emit dart-like projectiles to puncture enemies.

*[[Flood Bomber Form]]s: Large, bloated, airborne Flood forms. They attack by dropping [[Flood Growth Pods]] full of [[Infection Forms]] onto enemies.

*[[Flood Barracks]]: Organic structures that ceaselessly churn out a variety of attackers. They can't be destroyed by "conventional" weaponry, but players can damage them enough to force them into a withered, dormant state. The effect is only temporary, and given enough time, the Barracks will recover and begin producing more Flood forms.

*[[Flood Root]]: This form appears to be a defensive unit that "whips" or grabs units that get close to it.<ref name="gamespot.com">http://www.gamespot.com/xbox360/strategy/halowars/video/6204958/halo-wars-video-review?hd=1</ref>

*[[Flood Colony]]: A large structure found in heavily infested areas. Used as a "base" by the Flood.<ref name="gamespot.com"/> Regenerates only in the Campaign mode, otherwise opens up new base slots when killed.

*[[Proto-Gravemind]]: This appears to be the main [[Flood]]'s base's building. It seems to be connected to the [[Colony Form]]s, as whenever they take damage, the Proto-Gravemind takes damage too.<ref name="gamespot.com"/>

*[[Flood Nest]]: A small organic building, shaped like a jellyfish which creates [[Infection Forms]] and [[Carrier Forms]].<ref name="gamespot.com"/>

*[[Flood Launcher]]: Stationary tower-like forms that fire globs from their tops at enemies. These glob-like projectiles will release a spore cloud. This makes them dangerous to approach. It appears Spartans are immune to the clouds.

*[[Flood Den]]: A medium-sized building form which [[Flood Swarms]] and [[Flood Thrasher Form]]s come out of.

*[[Flood Vent]]: Large vents covered in Flood biomass which create [[Flood Bomber Form]]s.

Civilians are only encountered on Mission 4: Arcadia City, where the Spirit of Fire and Spartan Red Team helps them board Cargo ships for evacuation from the city. They function as normal infantry units, with five people per "squad" and a health bar that can be healed from a Repair Beam. They have no offensive capabilities at all.

Arcadian Police: They come armed with M6D pistols, but do little damage and are easily killed.  

=====Known Civilians=====

*'''[[Adam (Halo Wars)|Adam]]''' - Adam is a male civilian, possibly a child due to the fact of a mother heard asking where her son Adam is. He is  near a terminal. He is only seen when you activate a control panel that opens up a door to a tower. He runs out and goes toward Cargo Ship Two. If you can manage to escort him to the ship without him dying, you will unlock "[[The Real Winner]]" Achievement. This is difficult as if he gets shot once, he dies.

*'''Adam's mother''' - She is not seen, but when you move your troops close to the terminal, or activate it, she will ask if you have seen her son.

[[File:ThornBeastHW.png|thumb|right|180px|[[Thorn Beast]] seen in the middle of a battle.]]

Ambient life forms were planned to be encountered during gameplay. They may have been found on the battlefield, and might have reacted to the actions of the player's forces (such as firing a weapon, flying around or near them, etc.).<ref>[http://www.halowars.com/default.aspx ''Halo Wars'' Update; 2008-02-07, Ambient Life].</ref> Examples include the [[Space Owl]], the [[Harvest Whale]], the [[Arctic Beast]], [[Arctic Ice Hound|Ice Hound]] and some sort of [[eel-snake creature]] that has yet to be named.

These creatures have been cut from the game, as the only ambient life visible on any campaign or multiplayer maps are birds who do not visibly react to actions taken by the player.

Throughout the campaign and in Skirmishes, the player must advance their technology in order to increase their army's power. When technology is increased, more units, upgrades, and buildings become available. For instance, infantry units can receive additional members or stronger weaponry. Field Armories or Temples (and the upgrades within them) can become available with increased technology as well.

The tech tree is different for the two playable factions. When playing as the UNSC, the player advances by building and upgrading [[reactor]]s. The Covenant moves through the tech-tree in [[History of the Covenant|Ages]] by purchasing upgrades at the leader temple; players can advance to the [[Age of Doubt]] and the [[Age of Reclamation]] respectively. Players can also advance by capturing [[Forerunner Bonus Reactor]]s .

When a Reactor is built or an Age is researched, OR a Forerunner Bonus Reactor is claimed, the tech number on the top right of the screen goes up. If, say, a reactor is destroyed, the number goes down. Different buildings, units, and upgrades require higher numbers for use.  

Veterancy points increases a unit's statistics, such as attack, attack speed, defense, etc. This number can be calculated by counting how many stars a unit has above their health bar. This is the number of veterancy points said unit has. The stars, or ''Veterancy Points''. are acquired only after a unit or a group of units have defeated enemy structures, units, vehicles, or other combat related situations. They are also gained by upgrading the unit. A unit has a maximum of 3 stars, except a Spartan-Commandeered vehicle, which has a maximum of 14 "Veterancy Points" for Tanks/Grizzlies and Hornets/Hawks. All other Spartan-Commandeered vehicles have a maximum of 13 "Veterancy Points". Some special player units in campaign mode (example: [[ODST]]s in the level [[Anders' Signal (Level)|Anders' Signal]]) that have a maximum of 5 ''Veterancy Points''. A mist effect appears briefly over a unit when it gains a veterancy point, though this is hard to see unless closely watching the unit.

Certain characters belonging to both the Covenant and the UNSC have been confirmed to be "leader factions", which are sub-factions with unique units and bonuses. All of the Covenant leaders appear on the battlefield and have unique in-game abilities. The UNSC leaders on the other hand do not appear on the battlefield but instead have economic bonuses and "super units" (upgrades of normal units). Currently known leaders are [[James Cutter|Captain James Cutter]], [[John Forge|Sergeant John Forge]], [[Anders|Professor Ellen Anders]], [[Ripa 'Moramee]], an unknown [[Brute Army Commander]] and the [[Prophet of Regret]]. Each leader has a number of unique features, for the UNSC it's "super units", economic bonuses, unique units (Cutter's Elephant, Forge's Cyclops and Anders' Gremlin.) and leader powers ([[ODST]] Drop/MAC Blast, Carpet bomb and Cryo bomb, respectively to leaders stated previously) that can be called from the ''Spirit of Fire''. The Covenant on the other hand have a unique unit (two for the brute leader) and a "hero unit" (their leader) with their leader power attached to the "hero unit". The Prophet of Regret's ability is to glass enemy forces (known as the "Cleansing Beam" in ''Halo Wars''), which causes significant damage to both structures and units, however it also drains resources while active. His unique units are Sangheili [[Honor Guards]]. Ripa Moramee can go into a rage mode and wield two energy swords and can upgrade to infinitely cloak himself, but at the cost of draining resources for every second these modes are active.<ref>OXM January 2009 article</ref> Ripa Moramee will also have the ability to train [[Kamikaze Grunt|Suicidal Grunts]]. The Brute Chieftain can use his [[Gravity Hammer]] to create a vortex which sucks in infantry, then the player can press the A button to create a massive explosion. The Brute Chieftain's unique units are a pair of [[Brute Shot]] wielding Brutes (which can be upgraded to have jump packs) and the [[Chopper]].

Although Covenant leaders are limited to one unit at a time, they are some of the strongest units in the entire game and are immune to stun effects. They can also empower surrounding units.<ref name = "Hands On">2008-17-11, [http://www.videogamer.com/xbox360/halo_wars/preview-1380.html Halo Wars Hands-on Preview]. ''Videogamer''. Accessed on 2008-19-11</ref>

====UNSC Leader Powers====

*'''[[Transport]]''': Call a [[Pelican]] down to transport selected units (maximum of three vehicles and a number of infantry) to a selected area of the map.

*'''[[Disruption Bomb]]''': A bomb that deactivates any leader powers and prevents others being activated in a short radius during the effect.<ref name="gametrailers.com"/>

*'''[[Heal and Repair]]''': Heals all units and repairs all structures in a selected area.<ref name = "Gamereactor">2008-04-11, [http://www.gamereactor.no/grtv/?id=3396&sid=5bb9748a525446234980eb00694fb89a TGS08: Halo Wars Gameplay Presentation]. ''Gamereactor TV''. Accessed on 2008-17-12</ref>

*'''[[Magnetic Accelerator Cannon|MAC]] [[MAC Blast|Blast]]''': Calls down a MAC blast from ''Spirit of Fire''<nowiki>'</nowiki>s onboard MAC. Upgrades allow for more shots before the power has to recharge. This power can only be used by Captain Cutter.

*'''[[ODST]] Drop''': ODST pods, individually aimed by the user, are called down at 100 resources each. The pods will spawn a whole ODST squad. Note that it is much faster to drop them from their pods than producing them in a Barracks or via the Elephant, but beware; if your reactors are destroyed or a bonus reactor garrison squad is killed you won't be able to to drop more.<ref>http://e3.g4tv.com/e32008/videos/26921/Hands_On_Halo_Wars.html</ref> (Unique to [[Captain Cutter]])

*'''[[Cryo Bomb]]''': The Cryo Bomb freezes any units and buildings within the blast radius. Units are unable to move when frozen, and buildings halt all activity. When frozen, air units have a chance of falling to the ground, shattering instantly. The more the Cryo Bomb is upgraded, the freeze time and the chance to make air units fall increases. Note that this also has an effect on your team. (Unique to Professor Anders). Any units that are equipped with shields fare better against the cyro bomb and also have extra time escaping then other ground units.

*'''[[Carpet Bomb]]''': Calls in a bomber to wipe out a large area. Effective against mass infantry or ground vehicles. The more times it is upgraded, the stronger and larger the carpet bomb is. (Unique to Sergeant Forge)

===Black Boxes===

Black boxes are a new feature in the game. Black Boxes are collectibles in the ''Halo Wars'' campaign that when collected, they add new events in the [[Halo Wars Timeline]]. They look like black boxes with yellow stripes on them and can be picked up by any unit. When you collect one you can just resign straight away and you will still have it. The timeline covers many of the important events from the games and the novels. There is only one black box on each level in the game.

[[File:Mining.jpg|thumb|A concept of a Covenant mining facility cut from the final game.]]

Six units, the UNSC [[Cougar]], UNSC [[Fox Cannon]], [[Covenant Air Artillery]], Covenant [[Gorgon (Vehicle)|Gorgon]], the UNSC [[Falcon (Fighter)|Falcon]], and the UNSC [[Leviathan]] were under development early in the game along with the ability to actually construct individual buildings. The developers later announced that these units been cut, as they had decided to focus on more recognizable ''Halo'' units and simpler gameplay.

Before Ensemble conceived the idea for [[The Apex]], the storyline was supposed to feature a Covenant mining asteroid that was located at a [[Forerunner]] ore refining mechanism. This concept tries to show the scale of the large Forerunner machinery in place with machines that are still operational, although now controlled by the Covenant. In the end the mining aspect of the story was removed from the game.<ref>[http://www.halowars.com/default.aspx ''Halo Wars'' Update: On an Asteroid Far, far away...]</ref>

Another piece of deleted content is ambient life (i.e. Thorn Beasts, Harvest Whale, etc.) This may have been because the game already has some minor 'pathfinding issues' and the wildlife would have just been an obstacle.

[[File:1209090473 Screenshots 1280 003.jpg|thumb|200px|right|[[Covenant]] forces engage humans on the level [[Chasms]].]]

Just like ''[[Halo 2]]'' & ''[[Halo 3]]'', ''Halo Wars'' has strong characteristics of online gaming. ''Halo Wars''' live gaming characteristics include Direct voice communication & Online leader boards. Unlike any of the other ''Halo'' games, now your vehicles' and troops' armor will change to the teams color so you can get red Hunters, black Grunts, orange Hornets etc. There is no specific information regarding player ranking but players are able to achieve the ranks of Recruit, Lieutenant, Major, Commander, Colonel, Brigadier, and General. Multiplayer is up to 6 players at a time in a match. Two player online Co-op for the campaign story is available in the game.<ref name="xbox360fanboy.com"/><ref>http://carnage.bungie.org/haloforum/halo.forum.pl?read=874562</ref>

Each multiplayer map apparently takes place on a different "world", each with its own musical theme and playlist.<ref name="halowars.com">http://www.halowars.com/news/articles/archive/2008/04/28/Halo-Wars-Monthly-Update-4.28.08.aspx</ref> The Halo Rings won't be in the story, but may be included in future maps for multiplayer.

====Historic Battle Map Pack====

The [[Historic Battle DLC|Historic Battle Map Pack]] was released to Xbox LIVE Marketplace on July 21, 2009 and sells for 800 Microsoft Points. Along with 4 new maps, the DLC includes 4 new achievements as well. The maps included in this Map Pack are:

*[[Barrens]]

*[[Memorial Basin]]

*[[Blood River]]

*[[Glacial Ravine]]

''Halo Wars'' features a "[[Skirmish|Skirmish Mode]]", where the player can battle on multiplayer maps against an AI opponent in 1vs1, 2vs2 and 3vs3 match. There are 14 skirmish and [[multiplayer]] maps.<ref>[http://www.halowars.com/]</ref> There are two modes in Skirmish, [[Standard (Halo Wars)|Standard]] and [[Deathmatch (Halo Wars)|Deathmatch]]. Three more modes are available if you have the Strategic Options DLC (800 Microsoft Points): Keepaway, Tug of War, and Reinforcements.

In '''Standard''' mode, you start off with 0 tech level and 800 resources. All units must be upgraded including turrets and leader abilities. The population limit starts at 30 for the UNSC and 40 for the Covenant. In '''Deathmatch''', you start with 15,000 resources and a tech level of 4 for the UNSC, and 3 for the Covenant (Building a Temple increases your tech level to six, but more importantly give you your leader). All your units, buildings and leader abilities are already fully upgraded. Your population starts at 15 and you gain 10 population for taking over a base, up to 99. When you lose a base, the population limit goes down by 10. In '''Keepaway''' mode, you capture the flag from your opponent and bring it back to your base. In '''Tug of War''' mode, the objective is who can field and maintain the strongest army who wins. In '''Reinforcements''' mode, you have to adapt your tactics as you are granted waves of troops, much like an endurance battle.

Editors of ''OXM''s January 2009 ''Halo Wars'' article played on a multiplayer map called "Blood Gulch". It was stated that it is not the same map as that in ''Halo: Combat Evolved'', but some elements have clearly been used in the design for the map.<ref>''OXM'' January 2009 article</ref> It is also known that you have to win a Skirmish match on every playable map with all the different [[Hero Units|leaders]] in order to achieve the [[Playin' the Field]] and the [[Gallivant around the Galaxy|Gallivant Around The Galaxy]] achievements.
