'''Halo: Combat Evolved''' is a [[First Person Shooter|first person shooter]] science-fiction video game, created by [[Bungie Studios]], which was a subsidiary of [[Microsoft Game Studios]] at that time. It was released for the original [[Xbox]] game console on November 15, 2001, and is backwards compatible with the [[Xbox 360]] by downloading a free code patch on [[Xbox Live]]. It was also released for PC and Mac and it is one of the most popular video games for the Xbox with eight million copies sold. Its sales are rivaled only by its sequels, ''[[Halo 2]]'' and ''[[Halo 3]]''. This game is considered a classic even though it was released in 2001.  

''Halo: Combat Evolved'' has been made available as an Xbox Original game title for Xbox 360 since December 4, 2007 for download on [[Xbox Live|Xbox Live Marketplace]] for 1200 Microsoft Points.<ref>[http://marketplace.xbox.com/en-US/games/media/66acd000-77fe-1000-9115-d8024d53084c/ '''Xbox Marketplace''': ''Halo: Combat Evolved'']</ref>

[[File:Halo.gif|thumb|right|Halo Art (Installation 04).]]

''Halo''<nowiki>'</nowiki>s storyline is linear; there is a single ending in contrast to other first person shooters such as ''[[wikipedia:Deus Ex|Deus Ex]]'' that could have several different endings. It is presented to the player through an instruction manual, scripted events and conversations during the game, and a number of cut-scenes rendered using the game's graphics engine. This method of storyline delivery is common among modern video games. The Xbox version of ''Halo: Combat Evolved'' allows one player to play the campaign alone, as well as allow two players to play through the campaign in split screen. The [[Halo PC|PC version of ''Halo: Combat Evolved'']] allows only one player to play through the campaign.

#[[The Pillar of Autumn]] - "''Escape intact as Covenant forces board your ship.''"

#[[Halo (Halo: Combat Evolved Level)|Halo]] - "Seek out surviving Marines and help them fight the Covenant."

#[[The Truth and Reconciliation]] - "Board a Covenant ship in an attempt to rescue Captain Keyes."

#[[The Silent Cartographer]] - "Search for the map room that will lead you to the secrets of Halo."

#[[Assault on the Control Room]] - "Defend the Control Room against wave after wave of Covenant troops."

#[[343 Guilty Spark (level)|343 Guilty Spark]] - "Creep through a swamp to meet the only enemy the Covenant fear."

#[[Two Betrayals]] - "Re-activate the weapon at the heart of Halo... and learn the truth."

#[[Keyes]] - "''S''tage a one-cyborg assault on a Covenant ship and bring back the Captain."

#[[The Maw]] - "Destroy Halo before Halo destroys all life in the galaxy."

''Halo'', like Bungie's previous releases such as the ''[[Marathon]]'' series, has an intricate plot:

The {{UNSCship|Pillar of Autumn}} emerges out of [[Slipspace]] after barley escaping from planet [[reach]] to find a huge ring—a "halo" floating in space. The main character, [[Master Chief Petty Officer]] [[John-117]], is aboard the ''Autumn'' when the ship comes under attack by the [[Covenant Empire|Covenant]], an alliance of aliens and the arch-enemy of humanity. John-117 evacuates the doomed ship for the surface of Halo to protect the ''Autumn's'' artificial intelligence, [[Cortana]]. She carries highly sensitive military information, which would prove disastrous if she were captured by the Covenant. With the UNSC Marines by his side, Cortana providing direction, and his assault rifle ready and loaded, the Master Chief sets to finding out the mysteries of Halo and defeating the Covenant.

The first few levels of the game deal with an attempt to reach Halo's [[Control Room|Control Center]] to uncover its purpose. It is soon discovered that during an attempt to take control of a research facility, both human and Covenant forces have accidentally released something: [[The Flood]], as a result of the battle. The Flood is a parasitic race which received their name because of the way they swarm over all resistance. Free for the first time in thousands of years, the Flood sweeps across Halo, devastating Human and Covenant forces alike. The release of the Flood prompts [[343 Guilty Spark (Construct)|343 Guilty Spark]], the eccentric [[Forerunner]] artificial intelligence, to activate Halo's defense systems. Most obvious among these are the [[Sentinels]], flying robots equipped with beam projectors, but Halo's most powerful weapon is much more subtle and far more dangerous. Halo can fire a pulse that will wipe out all sentient life in the galaxy. As sentient life is the Flood's food, the Flood will not be able to survive, and will therefore perish. Technically the [[Installation 04|Installation]] only has a maximum effective radius of 25,000 light years, but the pulse would trigger other installations as well. This system is designed to stop the Flood from spreading through the universe if they escape confinement from Halo, by starving the Flood of any life source large enough to sustain them. This is the only possible solution to the destructive parasite.

 

 

 

==== Early Conflicts ====

{{Main|History of the United Nations Space Command}}

2160-2200: This is a period of brutal unrest in Human history in which [[National Governments]] and break-off factions fight for control of Earth and its colonies.

 

As overpopulation and unrest mounted on [[Earth]], a number of new political movements were formed including the neo-[[Communism|communist]] [[Koslovics]] led by Vladimir Koslov and the neo-[[Fascism|fascist]] [[Frieden]] based on the [[Jovian Moons]], which attacked the [[United Nations Colonial Advisers|UN Colonial Advisers]] on one of the moons, and UN-sponsored military forces began a pattern of massive build-ups which culminated in the [[Jovian Moons Campaign]], the [[Rain Forest Wars]] and the first [[Interplanetary War]]. After the successful [[Argyre Planitia Campaign|Marine attack on Mars]], recruitment drives and propaganda tactics strongly bolstered UNSC forces. They defeated the Koslovics and the Frieden on Earth and crushed their remnants throughout the Solar System. Both factions were defeated in the face of massive, unified UN military.

 

In the year 2291, the United Nations Space Command (UNSC) successfully developed humanity's first [[Slipspace]] drive, the [[Shaw-Fujikawa Translight Engine]]. For the first time in history, the rapid colonization of other worlds was made possible. By 2390, 210 worlds had been occupied by humans, and were being actively [[Terraforming|terraformed]] to suit man's needs. These worlds were to become known as the [[Inner Colonies]]. By 2490, the UNSC's fledgling interstellar empire had expanded to over 800 planets throughout the [[Orion Arm]] of the [[Milky Way Galaxy]]. During this period, the planet [[Reach]] became the headquarters of the UNSC military, and was destined to become the most heavily fortified world under human control.

 

{{Main|SPARTAN-II Program}}  

In 2517, several years before contact with the Covenant, the UNSC military embarked on a secret project to create a group of elite soldiers that would deal with occasional unrest in the Colonies. Codenamed SPARTANs, these [[Spartans#Augmentation_Procedures|genetically enhanced]] troops were trained from the age of 6 into a life of battle, and became a great asset against the Covenant. While humans suffered defeat after defeat in space, they could almost always prevail with the help of the SPARTANs in ground engagements. The main character of ''Halo''<nowiki>'</nowiki>s gameplay, the Master Chief, is a veteran SPARTAN of the SPARTAN II project after an unfortunate failure of the [[ORION Project|first SPARTAN program]]. All SPARTANS were given special armor designated [[MJOLNIR Powered Assault Armor|MJOLNIR]], which can increase their strength and speed. They were the only ones who could wear it as those without upgrades would not be able to withstand the reaction times of the armor and die.

{{main|Human-Covenant War}}

After [[First Battle of Harvest|first contact]] with the Covenant was made on the colony of [[Harvest]] in [[2525]], a series of brutal engagements followed. [[Admiral]] [[Preston Cole]]'s [[UNSC Battle Group X-Ray|fleet]] managed a [[Second Battle of Harvest|victory at Harvest]], but at a high cost - two thirds of his ships were destroyed. Despite significant tactical brilliance on the part of Human commanders, Covenant technology guaranteed a four to one kill/loss ratio in most space battles. One by one, the Outer Colonies fell below the onslaught, and by [[2535]], virtually all had been destroyed.

{{Main|Fall of Reach}}

By 2552, the Covenant had destroyed many of Humanity's Inner Colonies. In a move of desperation, UNSC orders a secret plan to capture a Covenant ship using a SPARTAN task force and find the coordinates of their home planet. All of the Spartans except three are chosen for this mission, and, led by the Master Chief, board a specially outfitted ship known as the ''Pillar of Autumn'' (under the command of Captain [[Jacob Keyes]]). This plan, however, is interrupted when the Covenant launch a surprise attack on the fortress world of Reach.

During this battle, Reach is overrun and the human fleet is obliterated. Worse still, the Master Chief thinks that all of the SPARTANs but himself are killed on the surface of the planet. The (supposedly) last remaining Spartan, the Master Chief, escapes with the ''Pillar of Autumn''. In accordance with the [[Cole Protocol]], the ''Autumn'' makes a blind Slipspace jump, and emerges in the vicinity of an unexplored and remarkable world.

The ''Pillar of Autumn'' exits Slipspace to find a mysterious ring shaped space station orbiting a [[Threshold|gas giant]]. The ring, quickly named "Halo", is obviously artificial. A Covenant [[Fleet of Particular Justice|fleet]], however, is also present, and a subsequent battle heavily damages the ''Autumn''. Captain Keyes initiates the Cole protocol 2 - all records of Earth's location are erased, the shipboard AI Cortana is given to the Master Chief to protect from the Covenant, and the ''Autumn ''is crash landed onto Halo. Cortana leaves the ''Autumn'' with John 117 in a [[Bumblebee]] escape pod which also crash lands on Halo.

Game play begins in earnest with the Master Chief's escape from the ''Autumn'', and continues upon landing. The player will soon discover the origins and purpose of this world - and uncover a threat that forces even the Covenant into retreat.

As a literary side note, the ring, "Halo", borrows heavily from the [[wikipedia:Ringworld|Ringworld]] of [[wikipedia:Larry Niven|Larry Niven]] and the [[wikipedia:Culture Orbital|Culture Orbitals]] of [[wikipedia:Iain M. Banks|Iain M. Banks]].

==Features==

[[File:1220238670 Menu.png|thumb|right|[[Halo PC]] main menu.]]

''Halo'''s gameplay was characterized by several features which set it apart from less acclaimed first-person shooter games of its time.

* '''Storyline Execution:'' '''Halo'''s gameplay and storyline are tightly interwoven, delivering in a convincing manner being consistent with the flow of the game.

* '''Vehicular Incorporation:''' ''Halo'' includes the option for players to control multiple land and air based [[Vehicles]] in third-person view. This Third-Person vantage brings a welcomed sense of immersion and enhances the specific points of gameplay, again setting Halo apart from contemporary first person shooters.

* '''Weapons System:'' '''Halo'''s new weapons system is unique in two major respects. The first is allowing players to carry only two [[Weapons]] at a time, thus forcing the player to make trade-offs as they progress throughout the game. The second change is a separate button for throwing [[Type-1 Antipersonnel Grenade|Grenades]].

* '''Artificial Intelligence:'' '''Halo'''s AI is quite sophisticated for its era. With a brand new advanced AI system, actions performed by the AI such as panicking after the death of a superior, diving out of the way of an oncoming [[Vehicle]], or taking cover from explosives and suppressive fire, helped ''Halo'' stand out from the rest of the first-person shooters being released at the time.

Movement in ''Halo'' is similar to other first-person shooters, allowing the player to move forwards, backwards, and strafe left and right independently of their aim. On the Xbox, moving and aiming are normally separated between the two analogue sticks; and on the [[Halo PC|PC]], between the mouse and the keyboard. ''Halo'' also allows the player to crouch and jump, although jumping from a high ledge will often result in death, or at least major fall damage. Damage from falling can be reduced or negated entirely with a well-timed crouch right as one lands. Additionally, if the player crouches at the peak of his jump he will be able to land on something slightly taller than if he were to jump without crouching. Also, if the player is jumping from a cliff he can make sure he is touching the wall periodically while he is falling. This will count as if he is touching floor, and every time the player touches the wall, the damage counter goes to zero. However, there is no visible damage counter during gameplay.

There are short summaries that describe the difficulties in Halo: Combat Evolved.

* '''[[Heroic]]:''' Your enemies are as numerous as they are ferocious; their attacks are devastating. Survival is not guaranteed.

* '''[[Legendary]]:''' You face opponents who have never known defeat, who laugh in alien tongues at your efforts to survive. This is suicide.

=== Enemies ===

The A.I. in ''Halo'' was superior to many other games at the time because the A.I. was sophisticated enough to attack other enemies in the vicinity, not just the Master Chief. If there is another faction in the area, the A.I. will engage it in the same way as they would fight the Master Chief.

* '''[[Covenant Empire|The Covenant]]:''' The Covenant, whose Fleet of Particular Justice was led by the [[Supreme Commander]], [[Thel Vadam]], is an alliance of different species. This includes the cowardly [[Grunt]]s, the [[Jackals]] with their portable [[Jackal Personal Arm Shield|Energy Shields]], the [[Elites]], master tacticians with their body covering [[Elite Personal Energy Shield|Energy Shields]], and the huge, metal [[Hunters]] with remarkably strong armor composed of some unknown alloy. The Covenant troops mostly carry plasma weapons of various power. They also make extensive use of vehicles such as Ghosts, Wraiths, Shades, and Banshees.

* '''[[The Flood]]:''' The parasitic Flood are encountered in three forms. The [[Infection Forms]] themselves, which usually die from a single shot or the Master Chief's energy shield. Exploding [[Carrier Form]]s, which cause major splash damage and release [[Infection Forms]]. Not forgetting the [[Combat Form]]s of former Humans or Sangheili whose nervous systems have been taken over by the parasite. Combat forms are the main and toughest of the three types. They often carry a Human or Covenant weapon.

* '''[[Sentinels]]''': These ancient robotic constructs are controlled by the Forerunner AI Monitor of Installation 04, 343 Guilty Spark. He is tasked with the defense of the ring against possible threats and to control the Flood infestations. Sentinels fire an orange colored beam that can strip hostiles of their [[Energy Shields]]. This weapon is designed to burn the Flood and has proven effective against many other enemies.

=== Allies ===

* '''[[Marine|UNSC Marines]]: '''The''''' '''Pillar of Autumn's ''complement of Marines assists the player often in the game. They are helpful, but on higher difficulties they are easily killed by enemies. They wield a variety of weapons. These include the [[MA5B ICWS Assault Rifle|Assault Rifle]], [[SRS99C-S2 AM Sniper Rifle|Sniper Rifle]], [[M90 Shotgun|Shotgun]], [[Needler]], and [[Plasma Rifle]]. Marines armed with Assault Rifles will occasionally throw [[M9 HE-DP Grenade|Fragmentation Grenades]]. The Marines will willingly ride in [[Scorpion]]s and [[Warthog]]s with the player and use the [[M41 Light Anti-Aircraft Gun|Chaingun]] on the Warthog while the player is driving. Unfortunately they are incapable of actually driving either vehicle. The only vehicle that Marines can drive is the [[Type-32 Rapid Assault Vehicle|Ghost]], which they pilot only briefly, though ironic. They appear in every level until the Library. When Marines are near death they will go into a berserk state, attacking every visible enemy.

*'''UNSC Crewmen:''' The crewmen of the ''Pillar of Autumn'' appear briefly as allies in the game. They are armed with [[M6D Pistol|Pistols]], but occasionally appear in combat unarmed. They have lower health than Marines and are prone to retreating and cowering in battle. They only appear in the levels ''Pillar of Autumn'' and ''Halo''. One melee is often enough to kill them and their habit of cowering tend to make them an obstacle to their comrades.

* '''[[Sentinels]]:''' Part of Halo's defense system, the Forerunner Sentinels, led by the Monitor 343 Guilty Spark, are hovering robotic drones. They attack the Flood, Covenant, and eventually the Master Chief. Although possessing a powerful [[Sentinel Beam|Beam Weapon]], they are not particularly resistant to damage (Their shields are especially vulnerable to Covenant weaponry, especially overcharged [[Plasma Pistol]]s and explosives.) They are seen as Normal and Shielded variants although both can be destroyed relatively easily. They help the player in the levels ''343 Guilty Spark'' and ''The Library'', but are enemies from the level ''Two Betrayals'' until the end of the game, acting as a Fourth Faction that attacks the Flood, Covenant, and the player when encountered.

All usable weapons in Halo: Combat Evolved belong to either the [[Covenant Empire|Covenant]] or the [[UNSC]]. The player can carry two weapons and up to 8 grenades (Four Fragmentation Grenades and Four Plasma Grenades).

Covenant weapons are better suited for reducing shields and typically fire slower than human weapons. With the exception of the Needler, they do not require ammunition or reloading. Instead, each weapon comes with its own battery. Once the battery is depleted the weapon must be discarded. Covenant weapons can also overheat (except the Needler) if fired for too long, after which they must be given time to cool down before they can be used again. There are a total of five Covenant weapons in the Campaign, three of which are usable by the player: the [[Plasma Pistol]], [[Plasma Rifle]], and the [[Needler]]. The two weapons the player can't use are the [[Energy Sword]], which disappears after you kill the Elite using it, and the [[Fuel Rod Gun]], which explodes after you kill the enemy using it. There are two additional weapons in the multiplayer mode of the PC version only, the Fuel Rod Gun and [[M7057 Defoliant Projector|Flamethrower]]. A plasma based weapon of the same type but with greater charge than the player's current one will appear as a swappable weapon. If the weapon has lesser charge, it is not swappable until the player's current charge falls low enough. Needlers automatically collect any ammunition from other needlers the player moves over. Needlers can also use some very rare individual packs of projectiles.

Human weapons, on the other hand, require ammunition and constant reloading. They are better suited for reducing health and do not overheat. However, on the Easy and Normal difficulty settings the difference is often negligible. There are five human weapons (not counting Fragmentation Grenades) usable in the Campaign and six in the [[Multiplayer]] of the Halo PC.

*[[M6D Personal Defense Weapon System|Pistol]] - The M6D is a powerful, accurate weapon that can be used up to 124 meters. It has good clip capacity (12 rounds), a 2X zoom scope for semi-sniping, and its bullets create a very small explosion on impact. The M6D Pistol is semi-automatic and recoil operated. If used correctly it can be the best back up weapon in the game, especially when you are sniping and don't have a Sniper Rifle. It can kill another player with three shots to the head and can dispatch a [[Hunter]] with one shot if you accurately hit their exposed flesh. It has been said to be one of the most effective weapons in the game, as it is fast, accurate, and deadly in the hands of a professional. In fact, the only level it does not appear in, "Truth and Reconciliation", is made difficult without this weapon, so the Sniper Rifle with more ammo capacity is used instead. Incidentally, this is also the only weapon that does not have a revival in Halo 3, though a similar weapon is used in ODST.

*[[MA5B ICWS Assault Rifle|Assault Rifle]] - The MA5B Assault Rifle is an automatic gas operated rifle that fires 7.62mm armor-piercing rounds. It has low damage per hit, and low accuracy at medium to long ranges. This weapon is good for close and medium ranges. The player will start off with one in most levels. It is a decent all around weapon, with a fast melee and good maneuverability. It is one of the best weapons against infection forms, grunts, invisible Elites, and sometimes Hunters. An interesting note is that no matter what weapons you're wielding, all of the cutscenes in ''Halo: Combat Evolved'' have the Master Chief holding an Assault Rifle - even in ''Two Betrayals'', where your starting weapons are the M90 Shotgun and the Plasma Pistol.

*[[Shotgun]] - the M90 Shotgun is practically the best weapon for picking off Flood Combat Forms and Carrier Forms, killing them with one hit if you are close enough. It is highly effective against Elites also. The shotgun fires a burst of 15 pellets, causing enemies in close range to be completely decimated in less than a second. Medium range is not so effective, and long range is useless altogether. Its close range capabilities are unmatched and are what makes it so effective against the flood.

*[[SRS99C-S2 AM Sniper Rifle|Sniper Rifle]] - The S2 variant of the Sniper Rifle features a night vision enhancement to the scope, which plays an essential part at the start of [[Truth and Reconciliation (Level)|Truth and Reconciliation]]. Its devastating power and range make it a formidable part of your arsenal. It carries four bullets per magazine and can pick off most enemies instantly, depending on their rank and the difficulty the player is playing. The Flood are barely affected by this weapon, sometimes taking 12 sniper shots to kill one. Thus, it is not worth the ammunition, which is often hard to come by on levels featuring flood.

*[[M19 SSM Rocket Launcher|Rocket Launcher]] - The Rocket Launcher is a devastating piece of equipment when used correctly. The Rocket Launcher will kill anything with one direct hit except Hunters and higher-ranking Elites on Legendary difficulty. It is the player's best choice against vehicles and groups of infantry.

*[[M9 HE-DP Grenade|Fragmentation Grenade]] - The technically named M9 HE-DP grenade, more commonly known as a Frag Grenade, will easily kill anything without a shield. Its bounciness gives it the edge in distance over the Plasma Grenade and it also packs a lot of force and splash damage. This means it is useful for [[Explosive Jumping|Grenade Jumps.]]

*[[M41 LAAG|Warthog Chaingun Turret]] - The LRV Light Anti Aircraft Turret is always equipped on the back of a Warthog, serving its purpose of eliminating enemies and vehicles quickly and effectively. Prolonged fire degrades accuracy.

*[[M7057 Defoliant Projector Flamethrower|Flamethrower]] - Usable only in multiplayer in Halo PC and the Custom Mapping Team level "343 Guilty Spark." It launches a stream of burning fuel over a relatively short distance, causing damage to enemies in front of the weapon and hurting them after they have been hit. It also has a very limited ability to set a surface on fire for a very short period of time. It fires from a unit mounted fuel tank that counts down from 100 to 0 units of fuel.

==== Covenant Weapons ====

*[[Energy Sword]] - A deadly weapon used by Zealot Elites and Field Master Elites. It can kill the player in one hit (although not on Easy difficulty where it takes three). It is advisable to dispatch the wielder quickly. The player cannot use the Energy Sword due to a built in fail safe.

*[[Plasma Rifle]] - It is a common light weapon in the Covenant army, primarily wielded by Elites. The Plasma Rifle has a high rate of fire and deals out a moderate amount of damage. A Plasma Rifle with a shotgun makes a good combo, Plasma Rifle for medium range and shotgun for close range. On Legendary, the Plasma Rifle is the most effective mid to close range weapon, best paired with an M90 Shotgun. It is also very useful for depleting Elite shields.

*[[Plasma Pistol]] - The Plasma Pistol, like the Plasma Rifle, is a directed energy weapon that fires bolts of superheated ionized gas otherwise known as plasma. Dumping energy into the firing mechanism will allow a build up of plasma that, when fired, will instantly and completely deplete shields regardless of strength. This overcharging makes it a valuable weapon in Multiplayer and against Elites, Jackals, and Sentinels in Campaign, usually when paired with an M6D Pistol.

*[[Needler]] - The Needler fires semi-homing crystal shards that explode approximately ten seconds after being launched and ignore most forms of personal energy shielding. While one explosion produces fairly light damage, several crystals exploding in succession can multiply the damage to fatal levels, and even more crystals in the same enemy will produce a large explosion. It is strange that independent ammunition that isn't already in another Needler is exceedingly rare.

*[[Fuel Rod Gun]] - The Fuel Rod Gun is used by the strongest and weakest of the Covenant species. It is carried on the shoulders of many [[SpecOps Grunts|Special Operation Grunts]], and a modified version is directly attached on the right arm of Hunters. In Campaign mode the gun explodes like a green Plasma Grenade when its Covenant wielder is killed. It is wieldable in Halo PC on most multiplayer maps. It has a limited battery when used by a player.

*[[Plasma Grenade]] - The Covenant Plasma Grenade is one of the most ingenious weapons in the game. Once activated, its outer layer converts to plasma, enabling it to fuse/stick to whatever it impacts (except for most walls and Hunter armor). It generates an electro-magnetic pulse that drains instantly any kind of shielding, no matter how strong it is, making it deadly even to enemies who survive the initial explosion. It is also handy for sticking enemies themselves, especially Grunts, who tend to run toward their comrades when panicking, as well as Elite Zealots.

*[[Shade]] - A stationary gun turret manned in third-person like a vehicle. It consists of a stand and a floating 360 degree rotating turret-like seat with control systems to its gun. It has a strong anti-tank ability, but the Covenant use it mainly against infantry. It can be manned by Elites and Grunts, and is similar to the turret mounted on ''Spirit''-class drop ships.

[[File:Halo 1 scorpion tank.jpg|200px|thumb|Halo CE Scorpion Tank on one of Halo's most celebrated Multiplayer maps, Blood Gulch]]

[[File:4wiki.jpg|200px|thumb|This image shows vehicle-on-vehicle combat a tactic that is repeated throughout the game.]]

The vehicles available to the player in this game are listed below:

*[[M12A1 Warthog LAAV|Warthog LAAV]] - A UNSC Light Anti-Armor Vehicle. The M12A1 is another variant of the Warthog with a triple barreled 102mm Rocket Launcher. It only shoots three rockets before reloading. Available only in Multiplayer on the PC version of Halo: Combat Evolved.

*[[M808B Scorpion MBT|Scorpion]] - A UNSC Main Battle Tank. It has a powerful 90&nbsp;mm cannon mounted on a turret, affixed to the rear of the chassis. It also features a machine gun aside the main cannon. It should be noted that both the main cannon and machine gun are inaccurate at medium to long range distances.

*[[Type-32 Rapid Assault Vehicle|Ghost]] - A Covenant Reconnaissance and Rapid Attack Vehicle. Its twin Plasma Cannons complement its high speed and agility, Allowing the user to blast enemies with the guns and run them into the ground. It is destructible in Campaign. It also has a feature that increases anti-gravity power in the front, causing the Ghost to nose up. This can be used to stabilize the Ghost after gliding over a cliff or hill, or to splatter opposition. Unlike Halo 2 and 3, this model has no boost but fires faster than its later models.

*[[Banshee]] - A Covenant Aerial Assault Aircraft. Very maneuverable. Armed with two plasma cannons and a fuel rod cannon. The Banshee's armor is strongest in front and very weak on the sides and back. It is destructible in Campaign but is, like all vehicles, impervious to permanent destruction in Halo PC's multiplayer. Unlike Halo 2 and 3, this model has no boost, and fires slower, making it an earlier, less effective model. The Banshee is unavailable in Multiplayer in the Xbox version. It is probably the lightest vehicle as it can take less than a M6D clip before it blows.

Several vehicles are not controllable by the player, like the UNSC [[D77-TC Pelican Dropship|Pelican Dropship]], the Covenant [[Spirit]] dropship, and the Covenant [[Type-25 Assault Gun Carriage|Wraith Mortar Tank]]. The Wraith requires ballistic aiming, firing large Plasma Bombs in arcs towards its enemies, similar to artillery. These bombs, if they score a direct hit, will often destroy vehicles or kill a Spartan if he/she is not equipped with an [[Overshield]]. Wraiths can be destroyed with explosive weapons such as the [[Scorpion Tank|Scorpion]]'s Main Cannon and the [[M19 SSM Rocket Launcher|Rocket Launcher]]. Note: both the Pelican and Wraith can be controllable via modding; the Wraith can be fired by the player, and features the M41 Rocket Launcher's targeting reticule. The Pelican can be flown, and if any Marines are alive and nearby, they may decide to hop in the player's Pelican.

Also, it is very easy to splatter enemies in Halo: Combat Evolved because the game's physics engine cannot discern between a fast and slow-moving vehicle, thus making it so that a slight touch, even by accident, will kill it. This is especially frustrating on the level "The Silent Cartographer"'s LZ, as Marines tend to dive underneath the level's many Warthogs, and in multiplayer, since the player can easily be killed by unoccupied vehicles.

=== Environments ===

''Halo'' features a wide variety of environments including human and Covenant star ships, ancient buildings on [[Installation 04|Halo]] itself, and expansive outdoor climates. The first level, ''Pillar of Autumn'', is fought entirely on the human star ship of the same name. The next level, ''Halo'', takes place in a temperate highland climate with open-air Forerunner structures scattered about. This level also contains the famous "Blue Beam Towers". ''Truth and Reconciliation'' begins in a rocky desert, but the setting changes to the titular Covenant cruiser about one-third of the way through. ''The Silent Cartographer'' occurs on a tropical island, with substantial combat both outdoors and inside futuristic Forerunner installations. ''Assault on the Control Room'' takes place in a snowy, icy area of towering cliffs and underground tunnels as well as high-tech suspension bridges and oft-repeated Forerunner structures built into and through cliff walls.

''343 Guilty Spark'' is a significant departure from these majestic environments, with combat in gloomy, exotic swamps and equally gloomy underground complexes that host the player's introduction to the Flood. The player is then teleported to the second of three entirely indoor levels, ''The Library'', encountering repetitive, forbidding hallways and massive elevators. Master Chief returns to the snowy climate of Assault on the Control Room for ''Two Betrayals'', visiting almost no new areas but, interestingly, traveling in the opposite direction. ''Keyes'' occurs in the same rocky deserts and the same Covenant ship from Truth and Reconciliation, albeit now heavily damaged, but this time the Flood are present in huge numbers. Finally, ''The Maw'' is set on the Pillar of Autumn with three major differences: the presence of the Flood, the heavy structural damage, and access to the Engineering section and service corridors of the ship, which were previously off-limits. In total, six of the ten levels feature a substantial amount of combat outdoors.

== Multiplayer ==

Up to four players can play together using the same-console split screen mode. It is also possible for up to 16 players to play together in one ''Halo'' game over a [[wikipedia:LAN|local area network]], using Xbox and/or Xbox 360 consoles that have been connected through an [[wikipedia:ethernet|Ethernet]] hub, or via Xbox Connect, which is a way of tunneling a connection via a PC. The game's seamless support for this type of play, and a few large maps that can accommodate up to 16 combatants, is a first for console games. Since the game was released before the launch of Xbox Live, mainstream online play was not available for this title. The Halo PC|PC version of ''Halo: Combat Evolved'' officially adds online play, also new vehicles ([[Banshee]] and [[M12A1 Warthog LAAV|Rocket Warthog]]), weapons ([[Fuel Rod Gun]] and [[Flamethrower]]) and maps (see list below) for multiplayer. The PC version of ''Halo: Combat Evolved'' does not support split screen multiplayer.

Multiplayer maps in ''Halo: Combat Evolved'' include:

*[[Blood Gulch (Halo: Combat Evolved level)|Blood Gulch]]

===Exclusive Multiplayer Maps (PC/Mac)===

*[[Death Island]]

*[[Danger Canyon]]

*[[Infinity]]

*[[Timberland]]

*[[Ice Fields]]

*[[Gephyrophobia]]

* '''[[Health]]:''' The player in ''Halo'' has limited, non-regenerating health, which can be fully restored by picking up health-packs. This aspect of the game was changed in ''Halo 2''. Running completely out of health will result in death, but having lower health does not impede player actions. A player's health can be reduced only if his shields have been depleted. If the player's health is at minimal levels they will faintly hear John 117's heartbeat. When the non-regenerative health idea was abandoned in ''Halo 2'' the medic packs disappeared completely.

* '''[[Shields]]:''' Master Chief's [[MJOLNIR]] Mk. V armor has a built-in shield, which protects all parts of his body from damage. The shield will decrease in strength every time it is hit by a weapon and will fail after taking too many hits. The amount of shield drain depends on the attacker's weapon but will quickly regenerate if it is not hit for a brief period of time. The shield represents a marked departure from most first-person shooters, in which one's health bar is basically augmented by picking up "armor". It is possible, in the single-player campaign at least, to have insufficient health points to survive the next section of game-play. ''Halo'' players, on the other hand, have a more-or-less permanent buffer of health at their disposal (assuming they manage to find time to regenerate the shield), making it less of a disaster to take hits in combat.

=== Power Ups ===

There are three power ups available in ''Halo'':

* '''[[Health Pack]]:''' (White octagon with red cross) Fully restores the player's [[health]].

* '''[[Active Camouflage]]:''' Drastically reduces the player's visibility for approximately 45 seconds, making all but a faint outline of him transparent. This effect is reduced or void if the player is holding a skull (in multiplayer), hit by weapons fire, fires their weapon, or when time runs out.

* '''[[Overshield]]:''' An enhanced, non-regenerating shield which is two times, (three times on enemies) the strength of the normal one. The overshield functions on top of the regular shield; when it is active, the normal shield does not take damage. In the single player game, the overshield is reduced only when the player is hit, while in the multiplayer game, it weakens gradually over time. One fully charged Plasma Pistol shot can take out the overshield and regular shield entirely. Additionally, while the over shield is charging, the player is completely invincible against almost every type of damage. The player can still be killed by [[assassination]], however.

===Reception===

''Halo'' was the main launch title for Xbox and is said to be the game that made the Xbox what it is today. It is widely renowned for saving the fledgling Xbox platform, as the Xbox lacked any titles to compete with Sony's PlayStation 2 or Nintendo's GameCube. ''Halo'' became an overnight success and managed to drive the platform from the brink of an early death. It went on to sell 8 million copies, in other words, 33% of all Xbox owners also owned ''Halo''. It was also critically acclaimed. IGN gave the game a 9.7 out of 10 and stated it to be the best Xbox game of all time. X-Play gave it a perfect 5 out of 5. The game got a perfect ten from EGM, and was 2002 Game of the Year for IGN, EGM, OXM, and AIAS. It also got a 9.5 out of 10 from Game Informer, and an average meta-score of 97 out of 100, making it the most highly rated Xbox game of all time. It was also called the game that reinvented a genre. OXM rated ''Halo: CE'' Number 1 in a list of the 100 best games of recent memory, saying "''The Xbox did not create Halo, Halo made the Xbox''".

== Trivia ==

*''Halo'' was originally being developed for the Mac and PC as a third person shooter, before Microsoft took interest in its development and purchased Bungie Studios, thereby owning a promising video game to use exclusively with Xbox.

*There are 8,087 lines of dialog, most of them randomly triggered during combat.<ref>[http://nikon.bungie.org/news.html?item=20971 Halo Dialogue Statistics, from the source] - HBO, November 12, 2007</ref>

*The ''Halo: Combat Evolved'' box art shows the Banshees in the background in their pilotless stance, yet they are still flying. Similarly, they are shown firing thin laser beams, rather than the plasma orbs that they actually fire in-game.

*Bungie mentioned that none of the characters in the E3 video for ''Halo: Combat Evolved'' had AI. In fact, all of the movement was actually scripted. This, however, was proven to be partly false. The AI will move to what are called "firing positions", which are not only places that the AI fire from, but places which the AI will not stop moving unless already in one, save for scripted command lists, although the AI will usually attempt to move to a firing position.

*In the ''Halo: Combat Evolved'' handbook, the [[Plasma Rifle]]'s "blueprint" is an overlap of a [[Needler]] underneath and the rifle on top.

*''Halo: Combat Evolved'' was originally planned to have a changing weather system which was mentioned in the August 2000 issue of ''PC Gamer'' magazine.<ref>[http://halo.bungie.org/pressscans/display.html?scan=pcgamer.0800 '''halo.bungie.org''': ''PC Gamer August 2000'']</ref>
