Video Game / Halo: Combat Evolved

"I think we're just getting started."
The Master Chief, Halo: Combat Evolved

Halo: Combat Evolved (released on November 15, 2001) introduced the Halo series from relatively Humble Beginnings. Humanity has been losing a war against the Covenant for the last 27 years, with the game taking place right after humanity has just suffered a devastating defeat at their most important colony, Reach. The story begins In Medias Res as the human warship the Pillar of Autumn, which had just escaped Reach, comes under attack by Covenant pursuers and is forced to make a crash landing on a mysterious ring-shaped mega-structure worshiped by the Covenant, known as Halo.

The player controls the Master Chief, one of the last of a group of specially raised and trained cyborg Super Soldiers: the Spartan-IIs. He is taken out of stasis during the attack on the ship, and his mission is to protect the survivors, find out what Halo is and what the Covenant want with it. Master Chief is the quiet type, but the AI program "Cortana" linked into his battle suit does most of the talking and provides plenty of tech support. Together they eventually uncover an ancient threat aboard the Halo which makes the Covenant look like a church picnic. The Halo itself has a much more malevolent purpose...

This First-Person Shooter developed by Bungie was the big title used to launch the Xbox console. Its superior graphics, interesting story and engaging gameplay made it a hit with critics and gamers alike, and it was hugely influential in bringing the concept of LAN parties, which was later expanded upon with Halo 2 being the Killer App for online gaming for the Xbox. The seamless integration of vehicles, the very expansive levels and the constant rotation of weapon types gave it a unique experience.

A port to Windows and Mac OS was released several years later courtesy of Gearbox Software, which added native online multiplayer without tunneling utilities, the Fuel Rod Gun (strangely treated as an energy weapon) and Flamethrower weapons for multiplayer, as well as the Banshee and a new Warthog with a rocket turret as multiplayer vehicles, along with the usual computer gaming features (enhanced graphics, mods, and so forth). The original release was not particularly designed for modification, however, and so they released a separate Halo: Custom Edition with some engine optimizations, exclusively used for multiplayer. It has its own separate download and installer, but requires a CD key from the retail version as well as having a CD check.

After many rumours of a remake for its tenth anniversary, Halo: Combat Evolved Anniversary was released by 343 Industries on November 15, 2011. The intended goal of the remake was to update the graphics, but otherwise replicate the gameplay and story exactly: the campaign mode uses the original Halo engine for gameplay, with a new, togglable graphics layer on top. The remake's multiplayer is run out of Halo: Reach, using a set of playlists that have been balanced to replicate the feel of Combat Evolved. The disc also comes with access to the Anniversary Map Pack, a new set of Reach maps that includes fan favorites from Halo 2 and Halo PC in addition to most of the maps from Combat Evolved. There is also a fan-made mod for the Custom Edition of the PC that overhauls graphics, level layout, and adds in the weapons and enemies of the more modern Halo games.

Three years later, the Anniversary version would see a rerelease on the Xbox One as part of Halo: The Master Chief Collection. The single player version is the same as the Xbox 360 version from 2011 (complete with the switchable graphics), but the original game's multiplayer mode has also been restored, meaning the original game's multiplayer is playable on Xbox LIVE for the first time.

Halo: Combat Evolved contains examples of:

  • Abandon Ship: The first level, featuring the crew doing a staged evacuation of the Pillar of Autumn while holding back Covenant boarders. Of course, after evacuating the only location to land on is the Halo ring itself, setting the stage for the rest of the game.
  • Affably Evil: 343 Guilty Spark.
  • A.I. Is a Crapshoot: Cortana is on your side. 343 Guilty Spark, on the other hand...
  • Alien Sky: anytime you have a decent view of the sky, you will find the gas giant planet, Threshold. Also the ring itself curves up and away in opposite directions. Oddly enough, if you look closely at the ring in the distance, you will see an obvious lighting error.
  • All There in the Manual: The events of Reach and many other elements of the war with the Covenant were explained in the Expanded Universe novels. Halo: Reach is a direct prequel to this game.
  • Alternate Reality Game: The Cortana Letters, while not a true ARG, served as a foreshadowing of things to come in the promotion of subsequent installments. These were a series of e-mails sent from Bungie-controlled addresses (and a couple of hidden messages on the discs of other Bungie games) to notable Marathon fandom people, authored, apparently, by an AI entity named Cortana, intent on warning humanity about an impending alien invasion. Over the course of the letters, she shared details about "the humorless war machine" she has to share processing space with, and the religious zealots "whose main form of worship takes place at the altar of orbital bombardment", as well as the "unbroken ring" whose creators have simply vanished. While many of the details revealed in this way back in 1998-1999 have since changed significantly (particularly in terms of Cortana's own characterization), the Letters gave away quite a good chunk of the game's plot.
  • Ancient Keeper: 343 Guilty Spark.
  • Apocalyptic Log: The Flood gets introduced through a video recording from the helmet cam of a (deceased) Marine named Jenkins. If you read the novelisation, though, you find out that the marine whose video the Chief watched wasn't dead at all he'd been turned into a combat form, but had somehow retained his consciousness, turning it into an And I Must Scream scenario.
  • Artistic License Nuclear Physics: Nuclear reactors are not bombs.
  • Artificial Brilliance: The unit A.I. in Halo: Combat Evolved was quite a step up from its contemporaries, and was praised by critics as one of its best technical points. Much of the player base likewise found the challenge of "smart" enemies to be a huge appeal of the game's combat.
  • Bash Brothers: Hunters are always encountered in pairs.
  • Better to Die than Be Killed: Basically what the Halo rings were designed to do.
  • BFG: The Fuel Rod Cannon, especially when wielded by tiny Grunts. The weapon is unusable by the player in the Xbox version.
  • Bleak Level: 343 Guilty Spark, which features few enemies and lots of wrecked equipment to drive home the creepiness factor. Most of the level is designed to confuse the hell out of players, playing initially more like a Horror game with guns than an FPS.
  • Body Horror: All victims of the flood suffer this, especially Captain Keys.
  • Book Ends:
    • The game begins and ends on the Pillar of Autumn.
    • In a more general example, the last three levels of the game consist of most of the entire first half revisited in the opposite order than when you first came through.
  • Boring but Practical: As you may learn from Jackals on Legendary, the plasma pistol is extremely useful when paired with a fast trigger finger. Semiauto fire + very short overheat + good against health AND shields = murder machine. The only gun that can compete with it for sheer damage output is the shotgun at close range. Plus you don't have to worry about chewing through batteries because it's the most common gun in the game!
  • Boss in Mook Clothing: Elite Zealots.
  • Big Bad: 343 Guilty Spark.
  • Bittersweet Ending: The threat of The Flood and Halo is destroyed by the destruction of the ring. As a result, everyone on the ring was killed and Master Chief and Cortana are stuck in space, and the Covenant are still out there, headed for Earth.
  • Captain Obvious: Cortana.
  • Cannon Fodder: The Grunts.
  • The Captain: Captain Keyes is running the show.
  • Car Fu: "Roadkill!"
    • Almost to Exaggerated levels, given that even the slightest nudge from a vehicle is an instant death. This was a result of the limited physics engine at the time which had difficulty translating collision forces into damage, hence any hit was made lethal.
  • Casual Danger Dialogue: Behold, the following:
    Cortana: "This thing is falling apart!"
    Master Chief: "It'll hold."
    Cortana: "We're not going to make it!"
    Master Chief: "We'll make it."
    Cortana: "Pull up! Pull up!"
    Cortana: "... You did that on purpose."
  • Co-Op Multiplayer: If Master Chief is the lone protagonist hero of the game, who is the carbon copy Player 2 is running around as? In the Expanded Universe Novel of the Events Master Chief's fellow Blue Team member Linda is fatally injured but placed into Stasis with him.
    • Fanon has this as an alternate reality where Noble Six didn't stay behind on Reach, or (more likely, considering the identical armor) where Linda didn't receive the fatal injury..
    • Sadly, this mode has been removed in the PC port, presumably because it was split-screen-only and no split-screen mode was present at all.
    • In the Pillar of Autumn there was a terminal in the cryo bay that shows the vital signs of the Master Chief in his cryotube. In Anniversary's co-op mode there are now two terminals. The second? It identifies Linda as the inhabitant of the cryotube that the second player emerged from.
  • Copy And Paste Environments: The game series is based on a psuedo sandbox-style level design, with you having to traverse many locations that are basically identical in appearance. It is most noticeable in this game, which takes place entirely on Halo and you travel through several identical areas and some levels are prior levels done backwards.
  • Deflector Shields: Master Chief, Elites, and the more powerful Sentinels are protected by these.
  • Disc One Final Dungeon: The Control Room.
  • Disney Death: Sergent Johnson gets Retconned into getting one. Even though, despite his fairly low screen time, Bungie did everything but show his actual death.
    • The Legendary ending shows him to be on the ring when it explodes. While this is non-canon, it would be very odd for a humorous non-canon ending to randomly kill off one of the few characters in the game for no apparent reason.
      • It was stated to be his twin brother
  • The Dog Bites Back: Marines do not tolerate treason - kill more than a couple of them and the rest will mutiny. And they're pretty formidable opponents, so keep them on your side.
  • Drives Like Crazy: "Oooh, a Warthog! That turret looks sweet, I call it!" Yeah, you'll regret that decision pretty quickly.
  • Early Installment Weirdness: No Brutes or Drones, you can't pick up energy swords, you can't pick up fuel rod guns (in the Xbox version), no one can hijack enemy vehicles - in fact the vehicles are indestructible - except for when the Covenant ones are occupied, and the pistol is incredibly powerful.
  • Earth-Shattering Kaboom: Granted, Halo is an artificial world but the last few levels have you trying to engineer one.
  • Elite Mooks: The Elites, obviously. In the level "Keyes" you begin fighting tougher, black-armored, Special Operation variants of them.
  • Elites Are More Glamorous: The Elites come in more varieties than any other enemy.
  • Enemy Chatter: "Wake up! Bad guys!" "He's here!" "Look out!" "Run away!" "Shoot you!" "Die Devil!" "HE'S UNSTOPPABLE!" "LEADER DEAD! RUN AWAY!" "GET IT OFF! GET IT OFF!" "OOH, AAH, GET IT OFF OF ME!!" "NO-HO-HO-HOOOOOO!!!"
  • Enemy-Detecting Radar: Foes appear as red dots on your motion tracker, and friendlies appear as yellow dots.
  • Escort Mission: The last part of "The Truth and Reconciliation."
  • Exact Time to Failure: The last Warthog run through the Pillar of Autumn takes place whilst a number of nuclear reactors are in the process of undergoing a massive meltdown, followed by a huge explosion. Cortana helpfully places a very exact timer onto your HUD to show when the meltdown will occur.
    • Interestingly, the time can actually halt and change throughout the section as the situation changes. This tends to suggest that the time displayed is actually Cortana's prediction of how much longer they have before they can leave in time to Outrun the Fireball rather than when the final detonation will occur.
  • Failsafe Failure
  • Failure Is the Only Option: The level Keyes. You'll never reach him in time to save him no matter how quickly you clear the level. Made all the worse due to Insurmountable Waist-Height Fence below.
  • Fan Remake: The Halo: Custom Edition for PC allows a number of mods to be made to the single-player campaign. A CMT (custom map team) campaign has already been released with Halo 2 and Halo 3 weapons and enemies added to the game, and the CMT is currently working on a new version incorporating modern-quality graphics.
  • First-Person Ghost: Played straight in this game, and averted in the sequels.
  • Foreshadowing: For the entire series. In the Control Room, you can see the ring that you're on (Installation 04 or Alpha Halo), but you can also clearly see six other rings in the hologram.
    • Sgt. Johnson's pre-battle speech on the Pillar of Autumn on Legendary difficulty yields this:
    Sgt. Johnson: Well, I don't care if it's God's own anti-son-of-a-bitch-machine or a giant hula hoop; we're not going to let them have it!
  • Frickin' Laser Beams: Most of the Covenant weapons.
  • Godzilla Threshold: Since the Flood is so dangerous, Halo is meant to wipe out absolutely all life in the galaxy in order to stop them.
  • Hanging Separately: The Humans and the Covenant, despite both being attacked by the Flood, are unwilling to help each other. In fact the Covenant will even prioritize Master Chief, even when being attacked at that moment by the Flood. Justified in that the Covenant are waging a holy war against humanity, and the Chief is seen as their version of the Anti-Christ; some new aliens aren't going to stop them from killing some more soldiers.
  • Harder Than Hard: The Legendary difficulty setting. As it says ingame: "This is suicide".
  • Heavily Armored Mook: Hunters are nearly invincible unless you can shoot them in their orange weak spots, you hit them with enough grenades, or happen to have a rocket launcher. Or a tank.
  • Insurmountable Waist-Height Fence: The level Keyes has the character start literally in the hallway right next to the end point, but is inaccessible due to locked doors. You can actually see into the room through a metal grating.
    • Likewise, just down the hall is a hole in the ship which you must jump down to continue through the level, but is easily small enough a gap for someone like the Master Chief to make.
  • Invisible Monsters: Elites with active camouflage.
  • Justified Tutorial: You're taught how to control your character under the pretext of a post-hypersleep examination. This is skipped entirely in co-op or on higher difficulties.
  • Laser Blade: Gold-armored Elites use these, and can waste you with one hit.
  • Law of Chromatic Superiority: Higher ranks of each enemy type are distinguished by the color of their armor. For example, red Grunts are better than orange grunts. In later games, this was modified so that higher ranking enemy types had very different-looking armor altogether.
  • Left the Background Music On: In one of the cut-scenes, some Marines are heading into battle while generic Heavy Metal plays. One of them asks "Why do we always have to listen to the old stuff?" and their sergeant replies that it is part of Earth's culture.
    • Word of God says that Bungie originally planned to license Steppenwolf's 'Magic Carpet Ride' or Rolling Stones' 'Paint It Black' for this scene, but was vetoed, resulting in the generic electric guitar.
  • Level in Reverse: Half the game is you moving into areas to fight the Covenant, the other half is you pulling back to escape the Flood.
  • Limited Loadout: Trope Codifier for the modern First-Person Shooter. Master Chief can wield any two of the game's eight weapons and four of each of the two types of grenades at once. Melee attacks are always an option, too.
  • Marathon Level: "Assault on the Control Room." "The Library" can also feel like this.
  • Mecha-Mooks: The Sentinels.
  • Mle Trois: The later missions feature a four-way conflict between the humans, the Covenant, Halo's sentinels, and the Flood.
  • Missing Mission Control: At the end of "Assault on the Control Room", Master Chief leaves Cortana behind to go and rescue Keyes, only returning two levels later. This is done so that the Chief's one constant companion is missing for your first encounter with the Flood.
  • Mooks but No Bosses: Not counting the Reactor Boss mentioned below, this trope is played straight.
  • No Name Given: The player character is never referred to by name, only by his rank.
  • Non-Combatant Immunity: Until you get a weapon in "The Pillar of Autumn," you never directly engage Covenant soldiers.
  • Nothing Is Scarier: You fight virtually no enemies during the beginning of "343 Guilty Spark," in order to build suspense.
  • One-Word Title: Bungie intended for the game's title to be just "Halo" alone, but as explained below, a Publisher Chosen Subtitle was added.
  • Our Zombies Are Different: The Flood count as Type PS.
  • Outrun the Fireball: Master Chief has to race through the Pillar of Autumn, while it's exploding.
  • Overheating: Covenant plasma weapons will overheat if fired continuously.
  • Plot Coupon: The Index.
  • Powered Armor: Master Chief's Mjolnir Mark V suit.
  • Precursor Killers: The Flood. More accurately, the Forerunner killed themselves and almost all other life in the galaxy in order to stop the Flood.
  • Psycho Strings / Drone of Dread: Typically used in music associated with the Flood, such as Shadows (Between Beams), Suite Autumn (Suite Fall), What Once was Lost (Unfortunate Discovery), Lament for Pvt. Jenkins (Private Service), Trace Amounts (Bad Dream), Library Suite (Dewey Decimate), and Alien Corridors (Xenoarcheology). The Anniversary remastered tracks especially turn up the horror factor.
  • Reactor Boss / Unplanned Manual Detonation: Cortana sets a counter to detonate the Pillar of Autumn's engines... and 343 Guilty Spark stops it. Master Chief then does it with rockets and grenades.
  • Redshirt: The ship crewmen from the first couple of levels. They have less health than even a Grunt, and are armed with pistols (if at all). They even wear red (and yellow, and orange, and blue, and on the bridge, even black) uniforms.
  • Redshirt Army: The UNSC Marines. Useless for almost everything except manning your Warthog's gun.
    • Unless they have sniper rifles. This was toned down in the sequels where you could switch weapons with them at will, to prevent players from handing NPCs the weapon and breezing through the levels.
  • The Reveal: We have two regarding Halo's purpose. The first was that it's a containment facility designed to prevent the Flood from escaping. The second is that Halo itself is a weapon that can and has killed all sentient life within 25,000 light years.
  • Scary Dogmatic Aliens: The Covenant.
  • Sci-Fi Writers Have No Sense of Scale: In the final mission, Cortana states that the Pillar of Autumn's self destruction will produce an explosion with a temperature of almost 100 million degrees (presumably Fahrenheit); this would be nearly 4 times as hot as the core of the sun.
  • Sealed Cast in a Multipack: If you play co-op, this is how both players begin the game. Otherwise it is simply Sealed Badass in a Can.
  • Sequel Hook: Master Chief muses at the end that this is only the beginning of something bigger. After the credits you can see Guilty Spark humming to himself, flying through space.
  • Shield-Bearing Mook: Jackals.
  • Shout-Out: Many to Bungie's older First-Person Shooter series Marathon, to which Halo is a Spiritual Successor. As Matt Seoll (who ran Bungie PR from the Marathon era up through the first Halo title) said, "Anyone will be able to enjoy Halo, but the ones who will enjoy it the most will be the old-school fans."
    • Also, the "Bandanna" skull in the Anniversary release is a shout out to Metal Gear Solid, where Snake can get a bandanna that gives infinite ammo.
    • The opening scene is also very reminiscent of Aliens.
  • Sniper Pistol: The human pistol. It's the single most practical weapon in the game, with a much higher accuracy and stopping-power than the so-called "assault rifle".
  • Sniping Mission: The first part of "The Truth and Reconciliation."
  • Sole Survivor: You are the only human left alive who was on Halo by the end of the game. This is retconned in the novels.
  • Spiritual Successor: To the Marathon trilogy. Pretty much every single bit of human tech, signage or terminology (as well as the related gameplay mechanics) except for the appearance and gameplay functionality of the MJOLNIR armour was lifted wholesale from Marathon and into Halo.
  • Standard FPS Guns: This game features a fairly standard lineup.
  • Sticky Bomb: Plasma grenades. Most enemies panic when stuck with one of these.
    Covenant Grunt: "OOH, AAH, GET IT OFF OF ME!!" (BOOM!) "GET IT OFF!! GET IT OFF!!" (BOOM!)
  • Stock Footage: Due to a coding error, Sgt. Johnson drives a Warthog behind Sgt. Johnson in his introductory speech. Anniversary, built on the same code, kept it.
    • The Legendary ending is supposed to feature his twin brother, so it was probably him we saw.
  • Tank Goodness: The Scorpion tank is an unstoppable force.
  • Theory of Narrative Causality: After concluding they need to self-destruct the Autumn to prevent Halo from being fired, Cortana states they need to retrieve the activation code from Captain Keyes' neural implant. Yet, when the self-destruct sequence is cancelled by Guilty Spark in the final level, the Chief just asks if they could destroy the engine manually. Getting Keyes' neural implant was never necessary to begin with, and the entire Keyes level (along with the first half of the last) could have just been skipped if they decided to do it that way from the start. To be fair (and this is brought up in the novels), from "343 Guilty Spark'' on, the player is operating completely outside his chain of command, answering only to Cortana. Going to find Keyes may have been a matter of reporting on the current state of affairs, as well as potentially warning the Marines about the far greater threat the Flood pose.
  • The Unfought: Guilty Spark again.
  • Timed Mission: The final level, "The Maw."
  • Tractor Beam: The Gravity Lift that allows passage in and out of the Truth and Reconciliation.
  • Unique Enemy:
    • In "343 Guilty Spark", there is the Paranoid Marine, a Marine driven crazy by the (so far un-encountered) Flood and will slowly shoot at the player when approached.
    • There is only one group of Flood Combat Forms that use active camouflage in the game, encountered if you stay too long inside the armoury in "The Maw".
  • Villain Decay: Starting with the events following The Reveal, the Covenant gets hit with this hard.
  • Well-Intentioned Extremist: Guilty Spark.
  • Wham Episode: 343 Guilty Spark. The Flood appears, as an Outside-Context Problem.
  • What the Hell, Hero?: Just as Chief is about to activate Halo, Cortana finally manages to free herself and angrily demand, "Do you know what he almost made you DO?!"note 
    • A more literal example: if the player betrays his teammates, they will tolerate one death before turning on him, often times yelling some version of this ("What the hell, dumbass?". However, if he kills Captain Keyees during "The Pillar of Autumn" Cortana will rather hilariously yell "What the hell?" before calling marine security teams to kill you.
  • You Just Had to Say It: After you first enter the titular Covenant ship in "Truth and Reconciliation," a marine comments that there might not be any Covenant on board. Immediately after, enemy contacts show up on the motion tracker. A second marine chides the first for tempting fate.
    UNSC Marine: "What? There's no Covenant? Think maybe nobody's home."
    (Covenant attack in large groups)
    Second UNSC Marine: "Contact! LOTS OF CONTACT!! 'No Covenant.' YA HAD TO OPEN YOUR MOUTH!!"
  • Your Size May Vary: The Pillar of Autumn is at least three times bigger in the final set-piece then it should be, with you explicitly driving at least 3 km to reach the Longsword space fighter. This happened due to the fact that the interior layout of the levels which take place on the Autumn were done before the exterior had been decided on and finalized.
    • It's quite funny because in every other aspect of the game Bungie went to excruciating detail in creating the scale of the game.

Tropes relating specifically to the remake, Halo: Combat Evolved Anniversary:

  • Arc Number: Guilty Spark mentions offhand that the original plan was to build twelve Halo installations instead of seven...
  • Battle in the Center of the Mind: One terminal has Captain Keyes struggling to remember who he is and fighting off the Flood infection. By the end, the voice of the Gravemind can be heard.
  • Bottomless Magazines: The purpose of the Bandanna Skull. Remember all that time you kept running out of ammo during "The Library"? Now, you never lose ammo when that skull is on. And you can still get achievements with it.
  • Call Forward: The terminals in Anniversary details video logs kept by Guilty Spark. One in particular has him talking about how he hasn't heard from his counterpart on Installation 05 for some time, wondering if containment was breached...
  • Canon Welding: The terminals interconnect a lot of the other games and EU together as the series has evolved significantly since the original game. Guilty Spark narrates most of them, with references to the other Monitors and things that showed up in later games.
  • Continuity Nod: The terminal videos have several, including to the expanded universe.
    • The Keyes terminal showing Keyes and his mental struggle with Gravemind is an expanded version of a scene that was in Halo: the Flood, the novelization of the first game. A young Dr. Halsey also appears in flashbacks from Keyes' memories, and her appearance is similar to what she looks like in the Halo: Legends anime, with elements of her Reach design. Their daughter also appears in this.
    • Linda-058 can be seen on the cryo bay status monitor next to the Chief, a nod to Halo: The Fall of Reach and Halo: First Strike.
  • Crucified Hero Shot: Keyes is shown in this as John finds him absorbed by the Flood.
  • Go Mad from the Isolation: The terminals show Guilty Spark going crazy over time. Can't blame the guy, though. I mean, if you had to stay inside a giant space ring for over 100,000 years, wouldn't you go a bit... insane?
  • Shot-for-Shot Remake: Halo: Combat Evolved Anniversary is identical in nearly every respects to the first game, the original game engine is used with a modern texturing engine overlapping it to give it new high-definition graphics and framerate. That means the game plays exactly the same (complete with a feature to toggle between the old and new graphics on the fly) and the cutscenes are similarly remastered (although, on close observation, it can be noticed that the cutscenes have been slightly modified from the original, primarily in character animation - most noticeable on the secret Legendary ending). Because of that, it isn't quite up to par with contemporary next-generation graphics, it's about on par with Halo 3 from 2007.
    • The only actual changes is the inclusion of terminals hidden within the original levels containing videos that ties the franchise more closely together as well as potentially hinting towards the story of Halo 4, as well as unlockable skulls that can be used to modify gameplay when replaying the levels.
  • Shout-Out: The marine that Master Chief rescues at the life pod looks almost exactly like Marcus Fenix, the hero of Gears of War, the Xbox 360's other major exclusive shooter franchise (he's noticeably missing if you examine the bodies at the crash site in the next level).
  • Updated Re-release / Video Game Remake: Halo: Combat Evolved Anniversary is a bit of both. The single-player mode actually runs on the original Halo: Combat Evolved engine, but with updated graphics using resources taken from Halo: Reach. The multi-player mode, on the other hand, has been rebuilt from the ground up using the Reach engine.

Alternative Title(s): Halo 1
