During the development of Halo Wars, a number of units were concepted, prototyped and cut from the game.

UNSC

Cougar

"The Cougar is a heavily armored anti-infantry support unit used on the battlefield, specifically rough terrain. Equipped with dual M68 gauss cannons and an automated gun with computer targeting. Capable of long range travel and speeds of up to 90MPH."

— Concept art description

The Cougar was designed as a UNSC AFV, equipped with two M68 Gauss cannons. Although anti-heavy armor fire would blow the Cougar away quite easily, this vehicle was highly effective in holding off enemy armored vehicles until slower armored units could arrive at the battlefield. The Cougar had gained infamy in several urban tactical situations prior to the deployments in the war against the Covenant.

It appeared as a somewhat standard armored fighting vehicle with two wheels up front and two pairs in the rear. It bore a small mounted turret armed with two M68 Gauss cannons, as well as a machine gun or grenade launcher on other concept art. There was a windscreen on its forward body, with two side windows to provide a fairly high amount of visibility for the driver, which would have proved useful. It would have been able to reach a top speed of 90mph.

The Cougar was ultimately cut from the game in favor of other vehicle ideas. Its shape may have proved the inspiration of the SP42 Cobra, as its role in Halo Wars was originally an anti-vehicle unit. The Cougar bears a striking resemblance to the World War II armored car, the M8 Greyhound. Another version of the Cougar is cut content in Halo Infinite, having a very similar appearance to its Halo Wars concept.

Falcon

"The UNSC Falcon is the primary air attack unit of the UNSC Army. With swift attacks and exceptional maneuverability a small squad of Falcons can be devastating to enemy vessels. Armed with sidewinder missiles and heavy armor piercing guns."

— Concept art description

Not to be confused with a cut vehicle of the same name from Halo 2 or the tiltrotor helicopter that appeared in Halo: Reach, the Falcon was a UNSC aircraft that got so far as having a 3D model made. The Falcon was a twin seater fighter aircraft planned to be used by the UNSC Army. Originally intended to be a usable unit, stored in the UNSC airpad, it filled the role of strike fighter, packing enough firepower to destroy enemy vehicles and infantry with "Sidewinder" missiles and heavy armor-piercing guns. Like several other units, it was cut from the final game before it shipped.

In terms of design, the Falcon uses forward-swept wings (giving it an appearance similar to the 20th Century Sukhoi Su-47), which are used to provide stability during steep dives, indicating an emphasis in air-to-ground combat. Another, smaller set of wing flaps are attached to the ventral hull, possibly to improve stability. It also possesses two inward-angled vertical stabilizers at the rear, and missile pods attached to the base of the wing and the ventral hull. At the rear of the craft are twin jet thrusters, capable of tilting to allow VTOL capability. Retractable landing gear appears to be located at the wing tips.

Fox Cannon

"The UNSC Fox Cannon is a mobil log[sic] range artillery cannon firing rounds to ranges exceeding 50KM (52.8 maximum). Capable of firing five rounds per minute with satellite targeting. Firing 175mm M197 projectiles with destructive results."

— Concept art description

The Fox Cannon was a UNSC vehicle cut from Halo Wars. It was to be a self-propelled artillery vehicle, capable of firing five shells per minute, and with great accuracy due to satellite targeting over a distance greater than 50 kilometers. The Fox was equipped with a 175mm cannon that shot the M179 projectile. Given its role, it was likely replaced by the SP42 Cobra.

Leviathan Mobile Firebase

The Leviathan Mobile Firebase is a UNSC vehicle concepted during the development of Halo Wars, but evidently never implemented. The vehicle is similar in size to the Mammoth, being many times the size of an M12 Warthog and serving as a mobile Firebase. The vehicle is seen to have several different configurations such as a "Suicide assault" variant with nose-mounted saw blades and a "Paris gun" variant equipped with a massive artillery cannon. However, the primary variant appears to be a vehicle that would fill a role similar to that fulfilled by the M312 Elephant in the final game, sporting numerous machine gun turrets, a mobile barracks and the ability to tow a Shaw-Fujikawa Translight Engine, like that seen in the mission Reactor.

Mongoose

Early on in the development of Halo Wars, the M274 Mongoose was intended to be included. The vehicle got as far as having a model created and implemented in game, though by the time of the "Sway" alpha, all that remained in the files was a handful of text strings referencing test_pj_mongoose.

To create this Mongoose model, Ensemble 3D artist Jenell Jaquays had to rely on observing screenshots of the Mongoose as seen in Halo 3, as Bungie were unwilling to share the original model file with Ensemble.

Prototype infantry

This prototype infantry unit was created by artist Gene Kohler. Little is known of it or its purpose in-game.

• 

Tiger Tank

The Tiger Tank is a unit referenced in the game files. Little is known of it, except for the below icon.

• 

Covenant

Air Artillery

"Recently sighted behind several front line battles, it seems that the Covenant have developed an air based artillery unit. With no on board defenses, it can be very vulnerable if dealt with promptly. However, its heavy plasma mortar cannons can lay waste to an entire UNSC base quickly and it is therefore critical that we gain more field information on this vehicle."

— Official description.

The Covenant Air Artillery was a unit cut from Halo Wars some time prior to January 2008. The vehicle was to boast three plasma mortars, and was intended for use in a ground attack role - noted to be especially effective against static bases.

Brute Tank

The "Brute Tank" is a vehicle cut from the game, notable for its high similarity to the existing Wraith. However, the Brute Tank instead comes equipped with a turret like those found on the Scorpion tank. Text strings in the "Sway" alpha build reference brutetank_power_hack_obstruction, possibly meaning the tank was to have some form of hacking ability. Presumably, this vehicle was intended to be used by the Jiralhanae and their Chieftain.

Although the Brute Tank icon found in the final release of Halo Wars depicts a Wraith with a Scorpion turret, some models seen in earlier builds have a more distinctive appearance of a Wraith with a more Covenant-style turret; these vehicles bear some resemblance to certain Halo: Combat Evolved concept art, shown below. Another piece of concept art uploaded to ArtStation by Nathan Stefan shows a vehicle very similar to the Brute Tank, though the image itself is named gorgon-005 - this vehicle bears little resemblance to the Gorgon, so the art's status is unclear.

Another icon depicts this vehicle with a dome shield-like ability.

Chimera

The Chimera was a Covenant unit cut from Halo Wars. It was a four-legged walker bearing slight resemblance to the Protos-pattern Scarab, though with a more hunched appearance.

Elite Rangers

Found in some screenshots and an animation reel uploaded by animator Charles Tinney, the Elite Ranger was evidently to be a flying infantry unit. Their design is that of the Elite Rangers found in Halo 2.

Gargoyle

Named only in game files, the Gargoyle was intended to be a Covenant bomber aircraft. In the final game, a menu icon is still present in the files to represent the unit.

Gorgon

"When we originally spec'd out the Covenant, we gave them a ground-based, antiair unit called the Gorgon (above left) -- a bulbous, biped walker that used heavy Needlers to rip apart thin-skinned aircraft. Once it was in the game, though, we realized that we'd created a recognition problem: was the Gorgon a vehicle or infantry unit? We intended for it to be a vehicle, but the legs were causing problems, since we also said that "anything with two legs that walks is a dude." The final nail in the Gorgon coffin? The Covenant already had too many ground vehicles; we needed more air units."

— Dave Pottinger on the Gorgon.

The Gorgon was a vehicle created for the Covenant and intended for use in the anti-air role. The vehicle was envisioned as a walker equipped with a heavy needle cannon, used to attack air targets. The vehicle's mech-based nature conflicted with Ensemble's philosophy that anything with legs was considered infantry, and the overwhelming abundance of Covenant ground vehicles - combined with the relative lack of aircraft - ultimately led to the Gorgon being scrapped and replaced with the Bkowe'nei-pattern Vampire. A very similar vehicle; the Reaver, was later implemented in Halo Wars 2.

Interestingly, a later Artstation upload by Nathan Stefan titled gorgon-005.jpg depicts a vehicle more similar in nature to the Wraith or similarly-cut Brute Tank.

Recon Drone

Present in the "Sway" alpha, the Recon Drone appears on an early version of the map Repository as a unit buildable in the map's central Sentinel factory alongside Aggressor Sentinels. Despite this Forerunner construction and neutral placement, the Recon Drone takes the form of a Yanme'e. The Drone has a complete model and animations, and is able to fly at high speeds around the map. True to its name, the Drone has no attacks, and is instead only intended for scouting.

Scarab (Protos variant)

"The Scarab has an anti-everything gun, and I'm losing."

— Graeme Devine's remark upon encountering the Scarab in the E3 demo.

Seen in the E3 2007 build and on the box art for Halo Wars, among other promotional screenshots, is the Type-47A "Protos" Scarab - the Scarab variant notably found in the Halo 2 campaign levels Outskirts, Metropolis and The Great Journey. In the final Halo Wars game, the Type-47B Scarab design notably used in Halo 3, Halo 3: ODST and Halo: Reach is used.

In the E3 2007 demo, the Scarab appears near the end in a short viginette, climbing out of a Forerunner underground shaft. The Scarab proceeds to rampage across the battlefield, destroying several tanks and other units, and must ultimately be destroyed via MAC orbital bombardment.

Forerunner

Cut Sentinel boss

While the Sentinels do appear on many maps and levels of the final Halo Wars game, this Sentinel design in particular does not. While superficially similar to the final game's Super Sentinel in design and proportion, it has a number of very notable differences; predominantly the massive size it has compared to most other units in the game. The unit was intended to appear on the campaign level Cleansing as a boss enemy, though was ultimately cut. The model for the Sentinel remains in the game files, unused. An image of the Sentinel in-game appears to show it emitting plasma mortar-like projectiles firing at the Flood forces below.

Interestingly, this design was later brought back almost unchanged in Halo Wars 2 as the Protector Sentinel.

Ambient AI

Creep

A number of maps in Halo Wars feature neutral AI factions such as rebels, Sentinels and Flood. These factions will typically be hostile to both the UNSC and Covenant. A number of additional factions were intended to be implemented in the game. These factions were developed under the codename of "creep", and include the following.

Heretics

One possible creep faction intended to be included in Halo Wars were the Covenant heretics - those who sought fit to defy the Covenant religion. Concept art reveals that Sangheili were intended to be soldiers in this faction, while unused files within the releases of Halo Wars and Halo Wars: Definitive Edition showcase additional Heretic Grunts. An additional texture file known as creep_heretic_ghost_01 indicates the Heretics would have access to the Ghost vehicle; piloted by a Sangheili.

Jackal pirates

Another cut creep faction that would have been included are the Kig-Yar pirates. Files for the Jackals are still available within Halo Wars, allowing the units to be spawned in via modding. The Jackals were to spawn in squads of four, armed with plasma pistols or needlers. The pirates would also have access to Kig-Yar Snipers armed with beam rifles.

Rebels

While an unidentified insurrectionist group does appear in the final Halo Wars game on maps set on Harvest and Arcadia, released concept art indicates the rebels were intended to be much-more fleshed out. Released concept art showcases a rebel "sci-trooper" wielding an EMP gun and an insurrectionist-branded Gauss Warthog.

Animals

Alongside the neutral factions, Halo Wars was intended to feature fauna as ambient AI in the game world. Some of these creatures were only concepted, while others were even modelled and textured for in-game implementation. For a list of other ambient life cut from other Halo games, see this page.

Arctic beast

The arctic beast was a creature concepted, modelled and textured for inclusion in Halo Wars, likely intended to spawn on maps set in the polar regions of Harvest. This creature was later canonised in 2015's Halo: Hunters in the Dark as the Chaefka; a species of life indexed by the Forerunners and present on The Ark. The following year's Halo Mythos saw a scene from the book visualised with a new illustration, using the arctic beast's design almost entirely unaltered.

Arctic ice hound

"I remember back in 2006 watching a show on Discovery channel called “Alien Planet”, it was based on a book called “Expedition: Being an Account in Words and Artwork of the 2358 A.D. Voyage to Darwin IV” by Wayne Douglas Barlowe (sadly out of print). Anyway, it’s a fascinating program and worth picking up the DVD. At the time we were beginning to concept Harvest and I remember coming in the next day talking about this show on Discovery and then running out and getting the DVD for the team so we could watch. I felt that the cycle presented on the show, which is as real on Earth as it is anywhere, was really well represented here (herd, hunter, scavenger) and that I wanted to see this in the worlds and environments in our game. So when you look at our concepts you’ll see that we have herd animals, hunters, and scavengers."

— Grame Devine, discussing the arctic ice hound.

This creature was one of a number of concepts developed during the discussions of the wildlife of Harvest. It was concepted and even modelled and textured, though cut from release.

Thorn beast

The thorn beasts are another cut creature seen fully modelled, textured and animated; they are present in the Halo Wars E3 2008 build and can be seen walking around the map around thirteen minutes into the demo. They do not appear to attack UNSC forces. Thorn beasts remain canon in the Halo setting; with the Chieftain character said to particularly enjoy eating them; they were later featured in the novel Halo: Contact Harvest as a delicacy enjoyed by the crew of Rapid Conversion.

Interestingly, Halo Wars is not the first time the thorn beasts were developed to appear in a Halo game; they were originally designed by Paul Russel during the development of Halo: Combat Evolved, where they were modelled with an identical design and similarly cut.

Space owl

"When Ensemble looks at making worlds come alive we look at more than trees, hills and cool water. We look at something we call "ambient life" which means things like cool space owls flying around (like this one) and creating a look and feel of a natural balance in the world. If these creatures react to the players interaction in the world (firing weapons for example) then that goes a long way to making the player feel that the world is actually someplace believable rather than an empty sandbox with an AI."

— Graeme Devine, discussing the "Space Owl".

The so-called "space owl" is another ambient creature concepted but ultimately never implemented in Halo Wars. The creature was described as having a wingspan of six feet.

• 

  Concept art for the creature.

Harvest whale

"After Harvest was attacked things didn’t go well for the population (Just read Joseph Staten’s excellent Contact Harvest!) but the wildlife fared even worse. As seas boiled, turned toxic and the ecosystem turned poisonous life on Harvest became impossible for creatures great and small. Our concept artists here have created one such scene of a beached alien whale being picked over by the last surviving wildlife on Harvest, the scavengers."

— Grame Devine, discussing the Harvest whale.

The Harvest whale was designed as part of the exploration for the wildlife of Harvest. This creature would likely not be seen as an ambient AI on the map, but instead a dead body appearing in the environment.

  Concept art for the whale.

Oxyaena

The oxyaena is another creature fully modelled and textured for inclusion in Halo Wars. The creature was present in the game's E3 2008 demo, and can be seen wandering the map at around one minute into the demo.
