Doom 3 is a 2004 First-Person Shooter in the Doom franchise, released for both the PC and Xbox. Despite its name, it's not a sequel to the original Doom games, as much as a reboot. It has a darker tone then the rest of the series, with aspects of Survival Horror.
Just like in the original game, you're a nameless, silent, badass Space Marine, who has just been assigned to the Union Aerospace Corporation's base on Mars. Upon arriving and reporting to your sergeant, you are given your first task: find a scientist who has gone missing in the old communications facility. At first glance, the place and assignment seem as dull as dirt, but as you speak to other marines and workers during your search, the creepier things start to seem. Many employees seem frightened and paranoid, and then there's the fact that the whole reason you were assigned here in the first place was to replace another Marine who died during an operation. You also overhear some rather suspicious conversations held by a high-ranking UAC lawyer and his lackey, and shadiest of all, the creepy and mysterious scientist Dr. Malcolm Betruger, who promises that "amazing things will happen". By the time you find the scientist, things are already creepy enough, but then Hell literally breaks loose, and you find yourself as one of the few people left alive in a base rapidly being overrun with grotesque monsters, reanimated and murderous former humans, and otherwordly, demonic imagery. It's up to you find and stop the source of the invasion, locate and aid any fellow survivors, and fight to stay alive.
An Expansion Pack called Resurrection of Evil was released in 2005, and takes place two years after the original story. In 2012, id Software released the BFG Edition, which includes a remastered and slightly retooled version of the original Doom 3 game (with an armor-mounted flashlight replacing the original's controversial flashlight system, and more ammo), Resurrection of Evil, an all-new mini-campaign called The Lost Mission (consisting mostly of cut content), plus The Ultimate Doom and Doom II, as well as the No Rest for the Living expansion that was developed for Doom II's Xbox Live Arcade release, making for a very packed Doom experience.
The game was adapted into two novels by Matthew J. Costello.
In 2008, id Software began work on Doom 4 to follow on from this game; the result came out in 2016 and is, once again a reboot.
Doom 3 contains examples of:
- Achievement System: Implemented into the BFG Edition, which features 50 achievements on the Xbox 360 version, 65 achievements on the PC version, and 66 trophies on the PlayStation 3 version. These achievements range from "clear Doom 3 under X difficulty", "find a particular item in the game", and "killing players in a specific way in multiplayer".
- Adaptation Expansion: The novelizations either benefited or suffered from this depending on your personal taste. They include a lot more information about the UAC, character backstories, and the state of Earth, but almost the entire first book can be skipped and not miss any parts of the game.
- Adaptational Wimp: Elliot Swann in the novelizations. Game!Swann is a hardass who willingly walks into the face of death, while book!Swann plays like an expy of Donald Gennaro.
- A.K.A.-47: The assault rifle is a modified FN P90, with an Aliens-style digital readout for remaining ammo.
- Ancient Astronauts: Earth had been colonized by ancient Martians — who seems to be humanoid creatures with the same size and width as Humans — who teleported there to escape a demonic invasion. Some scientists ask themselves if the Martians are ancestors of Mankind.
- Anti-Frustration Features: If your health is lower than 10 and you go into the next level, the game will bump your health up to 25 percent to give you a fair chance.
- Artifact of Doom: The Artifact in Resurrection of Evil.
- Artificial Brilliance: The enemy's combat AI is very simple, but their path-finding AI is actually remarkably well-done; if you use an elevator or ladder to escape from a charging enemy, they can actually circle around the entire map to make their way to your new location. This is only noticeable if you go out of your way to toy with the AI, however.
- Awesome, but Impractical: The laser sight that replaces the crosshair in Doom 3: BFG Edition if you're playing in 3D mode. It's a lazy, cheap hack that does not actually point at where your weapon actually fires, and also sways with your gun for further confusion. This is most noticeable in the first few levels, where you'll find it extremely difficult to get pistol headshots on zombies, or kill imps with one shotgun blast. Once you start getting automatic weapons it becomes tolerable, as you can just blast your way through the rest of the game without worrying too much about precise aim thanks to the increased ammo availability of the BFG Edition.
- Badass Boast:Swann: This is the last time. I'm tired of running damage control every time he makes a mess.
Campbell: Right. You're the control, and if that fails, I'm the damage.
- Big Bad: Dr. Malcolm Betruger, a Mad Scientist and Evil Sorcerer who turns out to be in league with Hell, and wants to bring that Hell to Earth.
- Bittersweet Ending: The unnamed marine succeeds in sealing off Hell and survives, and is found by the subsequent reinforcements, but innumerable lives were lost beforehand.
- Blackout Basement: The entire game is dark, but some areas are even more so.
- The Coolant Control Junction area of the Alpha Labs 2 level is completely dark, thanks to EMP surges as explained by a scientist (who's carrying a lantern himself), and escorting him to the exit is an option to avoid having to juggle your own light.
- The Hell level is really dark, and to make it worse, you lose all weapons at the start and don't get a flashlight until you return to Mars City. It's not as bad in the BFG Edition, where the armor-mounted light works as usual, and in Resurrection of Evil, where there's no inventory loss.
- Body Horror:
- Happens to Sergeant Kelly, who gets fused into a tank, and Dr. Betruger, who gets partially consumed by a demonic dragon.
- The first encounter with a Lost Soul sees it burst out of the head of a female character. Many players mistook what was happening for that character's head and spinal column detaching from her body to attack you, which if anything is more horrifying.
- Boss Arena Idiocy: The Cyberdemon can only be harmed by the Soul Cube. The Soul Cube can only be "charged" for its attacks by killing enemies, so if you fought the Cyberdemon one-on-one, he'd be unstoppable. Luckily, he has weak minions constantly attack you, enabling you to charge up your Soul Cube again and again.note
- Broad Strokes: Official descriptions for the spin-off Doom RPG imply this game is a prequel to the original Doom games, and that Doomguy in Doom and Doom II, and the Marine in Doom 3 are both the same character. However, Doom 3 takes place in 2145, while the original Doom took place in 2022. The Marine also looks considerably different from Doomguy, and many of the visuals and storytelling elements don't mesh between games.
- Chain Letter: You can find one by checking the emails from some of the PDAs you find. The Littlest Cancer Patient is dying in six months, and for each time the message is forwarded, the UAC will donate 3 credits per name to her treatment and recovery plan. According to the date stamps in the e-mails, the letter was sent out the day hell broke loose, so the UAC won't be making a large donation any time soon.
- Continue Your Mission, Dammit!: At various points, Kelly will tell you to continue. There may be a situation update in the announcement, or it could sometimes be general squaking (e.g. after the airlock in Communications Transfer).
- Damn You, Muscle Memory!: Doom 3: BFG Edition maps sprinting to the left thumbstick button like most contemporary shooters. But while those shooters only require you to tap the button once, in this game you have to hold it down to sustain the sprint. This can also be confusing for those that have played the original Xbox version where the sprint button is mapped to the left trigger. On the PC version of BFG Edition at least, players can remap their controls.
- Darker and Edgier: Definitely darker (har har), but it includes a storyline and several PDAs one can find to expand on how Hellish (har har) UAC became. It also introduces a lot more Survival Horror elements and contains jump scares, and makes combat a bit slower.
- Data Pad: The standard issue PDAs of UAC personnel. Their design is more or less like a modern day tablet, but thicker and with a slight curve at the bottom separating the screen from what looks like an analog pad; there's also a port at the top to insert video disks. They serve the role of mobile work stations, e-mail and video playback platforms, audio recorders and electronic keys with specific clearances. They can also download the data from other PDAs, including clearance status, and indeed in most Lock and Key Puzzle sections your task is to find the PDA of one of the people with clearance to the area you need to go to (which is always helpfully listed in the interactive panel beside the Locked Door when you try to unlock it).
- Death by Transceiver: Mars City Underground, the first level with combat, has the player character listening to people fight, panic and die over his radio every ten seconds after the hell invasion begins. There is even a console video depicting a scientist having his neck snapped by a zombie before cutting to static, and a marine being possessed on another screen.
- Deconstruction: The game goes at lengths to show just how terrifying it would be being a lone marine, trapped on Mars, with monsters teleporting from nightmare world.
- Destructible Projectiles: How can you evade the homing missiles of the Revenant without diving for cover? Throw up a flak wall with the Plasma Gun. If it's a straight line between you and the attacking Revenant, then it'll gets showered in the remaining plasma bolts and die before too long. This is also how you deal with Sabaoth's BFG blasts. This also works for the Mancubus fireball barrages, as well as the fireballs lobbed by Imps and Hell Knights, though in the latter case it's better to just strafe out of the way.
- Diegetic Interface: When the player is wielding a machinegun, plasma gun, chaingun, or BFG-9000, the ammo counter disappears from the HUD and is replaced by a number displayed on the weapon itself. BFG Edition changed this so the HUD ammo counter always shows regardless.
- Embedded Precursor: The Limited Collector's Edition of Doom 3 and Resurrection of Evil on the original Xbox includes the original Doom and Doom II. The latter also includes the Master Levels of Doom II. The BFG Edition also includes the first two Doom games.
- Everything Fades: Dead demons disappear in a fizzly animation. This was probably to lighten the load on the game's engine and RAM usage by cutting down on rendered objects. After being surprised one time too many by what you thought was just a corpse rising up and attacking you, you may just find yourself in the habit of destroying every corpse you come across.
- Evil Is Not Well-Lit: The Hell level is dark enough to count as a Blackout Basement, and in the original edition, you have no flashlight while you're there.
- Exploding Barrels: Has a variant on these with the yellow toxic barrels. Once you shoot them, they simmer for a couple seconds before exploding (though they will explode automatically if caught in the splash of another explosive).
- Feelies: Reprints of the Xbox 360 version of BFG Edition with a Xbox One compatible label includes a fold-out poster of the original Doom cover art.
- Fire and Brimstone Hell: Hell is this, mixed with pulsating flesh and rivers of blood.
- First Day from Hell: The marine has just arrived at Mars and is doing his first assignment only to have the planet being attacked by creatures from Hell within a few hours.
- Game Mod:
- Aside from stuff like the Duct Tape Mod, there are a total conversion or two. One of the most well-known, The Dark Mod, uses the game's engine to modernize Thief: The Dark Project (until the mod became a standalone fangame).
- Doom 3 Redux improves on the game's visuals, restores some cut features from original game, remasters the game's audio logs, and adds lots of modern tweaks thanks to a custom build of Sikkmod that allows for more advanced options while maintaining the original Doom 3 gameplay. Sadly it's only available for the base game and not Resurrection of Evil.
- Killatomate's Realistic Weapons mod tweaks how weapons handles in the original Doom 3 and Resurrection of Evil and making them feel, well, realistic. For example, the pistol becomes semi-automatic with proper recoil and spread between shots, the shotguns have been rebalanced spread and damage output with readjusted reloading, and the chaingun now has a retuned recoil, spread, velocity, and reloading animation. The sound effects also have been replaced with sounds from real-life guns for many of the weapons of the game.
- The UltimateHD mod for the BFG Edition, which not only improves some of the game's visuals and effects, it also readjusts some gameplay elements, gives enemies new AI behaviors (e.g. Imps will leap away from the player's line of sight), and retools the game's weapons and how they handle.
- Classic Doom for Doom 3 does pretty what it says on the tin, which is recreate the first episode of Ultimate Doom, Knee-Deep in The Dead, in Doom 3's engine. Also What Could Have Been, as Episodes 2 and 3 were planned, but scrapped during development. On the plus side, it has some awesome remixes of the first episode's soundtrack.
- Hell on Earth: Dr. Betruger's ultimate plan is to bring the demons to Earth.
- Helmets Are Hardly Heroic: Unlike the Marine in the classic games, both the Marine in 3 and the Engineer in Resurrection of Evil go bare-headed. That makes it a little jarring whenever you go out on the surface of Mars: you're told that your suit should have enough oxygen to get you by, which makes no sense as you're never seen putting on a helmet or even a mask.
- Hyperspace Is a Scary Place: Teleporting will result in you seeing a terrifying blood-tunnel filled with screams.
- Infinite Flashlight: The only upside of the torch is that it'll never run out of juice.
- Idiosyncratic Difficulty Levels
- Recruit: damage taken reduced to 60%, less enemies;
- Marine: normal damage taken, normal enemy rate;
- Veteran: damage taken increased to 170%; slightly higher enemy rate;
- Nightmare: damage taken increased to three hundred percent, more enemies, and your health constantly decreases to 25 points no matter what. Know that shiny Soul Cube you got at the start of the game? You will need it.
- Jump Scare: Happens often — in particular, Imps love to crouch down behind doors and around corners, just waiting for you to come by so they can lunge at you.
- Laughably Evil: Believe it or not, the demons are this in an Easter egg. In an easily-overlooked data terminal near the end of the game, you can download an e-mail where the demons try to instruct their fellows in how to invade:"Virgin blood is best."
"Goat blood must be no older than 3 days."
"Entrails must be removed and apportioned either before death, or no later than 30 min."
"Candles must be sorted by tallest in back to shortest in front - never the other way around!"
"Most important - pentagrams must be drawn from the center to the outside and left to right."
- Life Drain: When the Soul Cube's flung, it kills the demon and transfers all of its remaining life energy to you. Goes well with the lack of medkits late in the game.
- MacGuffin: The Artifact in Resurrection of Evil.
- Mad Scientist: Dr. Malcolm Betruger, to literally diabolic levels.
- Meaningful Name: The name of Dr. Betruger means something along the lines of "scammer" in German. They probably intended it to be more like "traitor", but that would be "Verräter".
- Meat Moss: Some areas are covered with, for lack of a better word, flesh masses that look like turds or tentacles or minced meat. If you shoot them, they sound like you're hitting steel; whether it's intentional or not, nobody knows. Sergeant Kelly mentions them over the radio before you first see them, and
- Modern Stasis / Schizo Tech: It's 2145, humanity has an established base on Mars, has mastered plasma technology, and is foraying into the science behind atomic structure (the MFS Compactor comes to mind) and teleportation... and yet:
- The most commonly found storage medium is a square-foot disk with capacity for only a few minutes of video and/or audio.
- Security forces lack any kind of enhanced vision, being forced to rely on big Mag-Lite style handheld flashlightsnote (armor-mounted with horrible battery life in BFG Edition) with very bad quality reflectors full of artifacts and dark spots.
- All projectile-based weapons seem to use black powder given just how much smoke they produce per shot. The grenade smokes out so much, it seems to have a burning fuse despite the apparent electronic activation.
- You'll occasionally come across what appear to be iPods in docking stations.
- All UAC workers must use a standard issue PDA that is clunkier and less versatile than most of the cheapest tablets you could find as far back as 2012 in reality. It could be stretched as them being made bulky to prevent damagenote , while the UAC would've had their IT department lock them down to a business-use feature set.
- Minimalistic Cover Art: While the standard cover as seen above depicts a Hell Knight, the Limited Edition for the Xbox release came in a steelbook that simply depicted the game's logo against a grey background with a satanic image, some scratches, and nothing else. The cover art for the BFG Edition is even simpler, with the logo against a nearly black background resembling a wall.
- Monster Closet: Demons have a bad habit of popping out of them. Gets ridiculous when they're literally hiding in the walls; you'll walk past a section of wall, hear a door that you couldn't see pop open, then get smacked in the back of the head with a fireball.
- Mook Debut Cutscene: Many of the demons get this, with the exception of a handful.
- Morton's Fork: Combined with But Thou Must! when at the planetary communications array. For half the game, your entire goal (according to Sergeant Kelly — who may or may not be acting honestly) has been to send a distress call to Earth. When you arrive, you are presented with two options; obey your orders and send the distress call or obey Swann (who technically outranks everyone) and shut down the array to keep the invasion isolated to Mars. Either choice results in the same end - if you obey Sergeant Kelly, then the distress call is sent but you're later told that this just means the demons have a free ride to Earth. Cancel the message and Swann congratulates you for seeing the bigger picture... only to be interrupted by Betruger, who overrides your control and sends the message anyway.
- Mythology Gag:
- When the player teleports to Hell late in the game, they lose all of their weapons and ammo and need to scavenge replacements. Said replacements just happen to be the Doom 3 equivalents of the original lineupnote .
- The ancient tablets depicting the battle between the Martians and demons is the cover art of the original Doom, except Doomguy is carrying the Soul Cube rather than a submachine gun.
- The mini-boss fight against the first two Hell Knights at the end of Delta Labs is a throwback to the fight against the "bruiser brothers" Barons of Hell that served as the bosses of the first episode of the original Doom.
- No Celebrities Were Harmed: Dr. Betruger bears a striking resemblance (both physically and in voice) to Sir Anthony Hopkins. In particular, to Hopkins playing Hannibal Lecter.
- Nothing Is Scarier: The first part of Delta Labs 1 has no combat at all, instead involving monsters passing by and appearing and disappearing just outside your view.
- Omnicidal Maniac: Betruger is essentially selling out the entirety of humanity to a gruesome end for a taste of power, from what can be gathered from his motivation.
- Obviously Evil: Come on, just take one look at Doctor Malcolm Betruger.
- Only Six Faces: Only has a handful of faces for the various human NPCs, which are re-used frequently. This is most noticeable in the opening Scenic Tour Level, where you can find two guys with the exact same head standing in the same room.
- One-Winged Angel: By the end of Doom 3, Betruger is transformed into a demonic dragon. In Resurrection of Evil, he puts up a hell of a fight with his new powers.
- Regenerating Health: Inverted in Nightmare difficulty, where your health constantly decreases by five points every five seconds until it hits 25.
- Ridiculous Future Sequelisation: A PDA message says "The new Quake-43 game blows my mind."
- Scenery Gorn: Considering that the game combines then-stunning graphics with horrific and grotesque imagery, set in dark and run-down research facilities and the bowels of Hell itself, this is a given.
- Scenic Tour Level: Unlike most examples, they give you a gun and even allow you to murder your co-workers even before things go to hell.
- Sean Connery Is About to Shoot You: Or rather, a Hell Knight is about to devour you on the game's standard cover.
- Sequence Breaking: Memorizing some of the security codes can do anything from unlocking powerful weapons early to circumventing an entire PDA hunt.
- Set a Mook to Kill a Mook: It doesn't happen as often as this game's predecessors, but it's possible to get enemies accidentally hit each other which will cause them to in-fight one another. There's an achievement in BFG Edition for pulling this off.
- The logo for the "Super Turbo Turkey Puncher 3" arcade machine is a nod to the logo for Street Fighter Alpha 3 and the game's developer, "Nabcon", is likewise to Street Fighter developer Capcom. The button layout on the arcade cabinet is also an allusion to Street Fighter, albeit with two extra buttons to the right of the six colored buttons.
- Although it's a magazine-fed, semi-auto handgun rather than a revolver like other series to reference it, the basic pistol in the game is clearly influenced by the blaster from Blade Runner.
- Several parts of the architecture and atmosphere, most evidently the sections involving monorail rides to certain locations where one can observe the environment and background events, are clearly made in tribute to the original Half-Life.
- The Smurfette Principle: There is one female employee that you meet in the entire game, and she dies as quickly as she's introduced.
- The Stoic: The marine. Never shows any form of emotion on his face, even fear, just frowns when new sorts of monsters appear. The only time he shows fear is when he meets the Cyberdemon.
- Stupid Evil: Dr. Malcolm Betruger, who apparently has no actual motive for attempting to transform Earth into Hell and its people into screaming demon-fodder. It is implied, however, that he has been possessed or is in some way controlled by the demons. The novels indicate he was an ordinary scientist who was subject to More Than Mind Control; alternatively The Lost Mission campaign indicates he always had an obsession with the occult and was offered ultimate power by the demons in exchange for Earth. Resurrection of Evil shows that the demons turned Betruger into a powerful demon in exchange for his aid, so that was probably part of his motivation.
- Teleporter Accident: A PDA audio log details how an electrical short led a lab chimpanzee being split in half. Literally. Her torso ended up on the destination marker, and her lower half stayed behind.
- Unique Enemy: In the second level you encounter a "fast zombie" in the infirmary. It can jog almost as fast as you can when not sprinting, and would have made a pretty challenging enemy if encountered in large numbers. The one you see in the infirmary is the only one in the entire game, with all other zombies being the standard "slow shambling" type or the average speed "Bernie".
- Only four riot shield Z-Secs appear in the base game, all of them in the same level. They do not appear in the original Xbox version.
- Updated Re-release: The BFG Edition features remastered versions of Doom 3, the Resurrection of Evil expansion pack, and a new set of levels cut from the original game in the form of The Lost Mission, all with improved lighting and rendering, support for 3D TV displays, a new (though optional) checkpoint system, re-tooled gameplay elements (e.g. more enemies to battle, shoulder-mounted flashlight, more plentiful ammo), and achievement/trophy support. This also bundles the HD ports of The Ultimate Doom and Doom II: Hell on Earth, which also gives PC players the ability to play the previously console-exclusive No Rest for the Living episode for Doom II.
- Video Game Cruelty Potential: All of the survivors you meet can be straight up murdered either for giggles or to charge the nightmare mode item; you can even do this before the demonic invasion begins. In fact, this is actually a smart thing to do, as many of the civilians in the intro sequence become zombies. One of the cruelest is activating a machine that will strip or melt the flesh off a scientist's bones, complete with a few seconds of horror and terror as the scientist realizes what is about to happen to him. In the BFG Edition, this one gets you an achievement.
- Villain-Beating Artifact: The original version requires that the player use the Soul Cube to take care of the Cyberdemon. This was changed both in later patches of single-player mode and in co-op mode.
- Wrong Genre Savvy: Sergeant Kelly seems to think that the invasion needs to be treated like any other enemy force, and commands Doomguy to send a transmission for reinforcements. Too bad that that is exactly what Dr. Betruger wants, so as to use those ships to have the demons invade Earth. It ultimately doesn't matter because he would have sent the transmission anyway if you hadn't.
Doom 3: Resurrection of Evil contains examples of:
- Absurdly Spacious Sewer: About two-thirds into the fifth Erebus level, players must make their way through the a series of waste tunnels containing toxic waste which requires the player to equip a special helmet to proceed through the tunnels and pick up tanks to keep the power on the helmet running. The helment mechanic however was completely removed in BFG Edition, however.
- The Berserker: What the Artifact turns the Marine into with the appropriately named "Berserk" upgrade garnered from defeating the Berserk Hunter.
- Bullet Time: After defeating the first boss of the game, the Helltime Hunter, the Artifact absorbs its ability and allows the Engineer Marine to enter bullet (hell) time.
- Catch and Return: The Grabber other use is being able to pick up enemies' projectiles (e.g. an Imp's fireball) and fire it back at them, which is demonstrated early on by a fatally wounded marine before dying and passing on it to you. Killing enemies in this fashion may save some ammo.
- Earn Your Happy Ending: A common interpretation of the vague ending of Resurrection of Evil. By the climax, every single person besides the Engineer Marine and Dr. McNeil is dead. McNeil orders the marine to shut down all the core systems in Phobos Labs, including the life support system, to power up the old teleporter so he can reach the old Delta Labs and eventually Hell itself to return the artifact and stop the invasion. After battling his way through the demons, the Engineer Marine reaches Betruger/Maledict and is mortally wounded in the battle, but manages to destroy him with the artifact using his last ounce of strength. As the screen fades to white, McNeil's voice can be heard saying "Marine, welcome home", implying that the two are in a better place for their sacrifice.
- The Hero Dies: Possibly. See Earn Your Happy Ending above.
- The Internet Is for Porn: A worker named James Owens in the Phobos labs was having problems with his computer running poorly and e-mailed a technician to find out what was wrong with it. He gets a reply from the technician who found on about Owens browsing through porn sites and may have attracted a virus from there.
- Lightning Bruiser: The Engineer Marine is this is spades once he has the fully upgraded Artifact. So fast that everything else is in bullet time, can punch hard enough to kill a Hell Knight in 1 hit, and is completely immune to any form of damage.
- Nice Job Breaking It, Hero!: The Engineer Marine's first action upon seeing the Artifact is to just walk up and grab it. This causes the Artifact to instantly vaporize his entire team, reopen portals to Hell, and start another invasion attempt.
- Nigh Invulnerable: The Engineer Marine becomes this through the Artifact once it absorbs the power of the Invulnerability Hunter.
- Sawed-Off Shotgun: The Super Shotgun you find in Sergeant Kelly's office has a noticeably short barrel for what is supposed to be a hunting shotgun.
- Short-Range Shotgun: The shotgun and Super Shotgun. Though still short ranged, the Super Shotgun is actually a bit more accurate than the regular shotgun since there's a larger central grouping of shot.
- Shout-Out: One of the PDAs you can find belonged to Nathan Reynolds.
Doom 3: The Lost Mission contains examples of:
- Cut-and-Paste Environments: Many areas of the mission pack are simply made up of rooms from vanilla Doom 3 copy and pasted together. Justified as these were levels cut from Doom 3 with some of sections being rebuilt or repurposed for the final game.
- Downer Beginning: The Lost Mission starts where Bravo Team was ambushed by demons from the main campaign, followed by a marine's lifeless body being dragged through a blood-soaked duct.
- Hero of Another Story: Dr. Meyers and the Bravo Marine manage to destroy a long-range teleporter before the Doom 3 marine even completes his mission.
