A board game by GamesWorkshop, currently in its third edition.

In the ''TabletopGame/{{Warhammer 40000}}'' universe, [[SpaceIsAnOcean space is very much an ocean]], complete with {{ghost ship}}s drifting silently through the void. These ships, known as Space Hulks, are both prized and feared by the [[TheEmpire Imperium of Mankind]]: prized, because their ancient holds often contain artifacts of lost technology and relics of the long-forgotten past; and feared, for their dark and twisting corridors often hide unseen threats and lurking horrors. Among the greatest of these horrors are the Genestealers, the vanguard organisms for the [[HordeOfAlienLocusts Tyranid Hive Fleets]]. While each Genestealer is an alien killing machine with claws that can [[AbsurdlySharpBlade shred the toughest of personal armor like it was tissue paper]], their true threat lies in their [[FaceFullOfAlienWingWong reproductive cycle]], which [[TheVirus transforms the victim]] into [[MindRape a willing pawn of the Genestealer]] as well as [[BodyHorror turning all their future children into Genestealer hybrids]]; suffice to say that even a single Genestealer, if left unchecked, can spell the doom of an entire world. Thus it falls to the {{Space Marine}}s, [[SuperSoldier humanity's greatest warriors]], to board any Space Hulk that drifts into an inhabited system and cleanse it with blade, shell, and fire -- or die trying.

The game draws heavy influence from the movie ''Film/{{Aliens}}'', with a small team of heavily-armed specialists attempting to accomplish their objectives while under attack from [[ZergRush endless waves of killer alien bugs]]. Three editions of the game have been released; the most recent (a limited edition released in 2009) focuses on the Blood Angels chapter of Space Marines and their efforts to cleanse the Space Hulk ''Sin of Damnation''.

For The Chief Characters who appear in the ''Deathwing'' Expansion, refer to the Deathwing Section of The Characters/DarkAngels Character Sheet.

In 2010, FantasyFlightGames released a [[CardGames card game]] remake of it called DeathAngel.

Has three official video game adaptations released to date, one simply named ''Space Hulk'' that focuses on the Dark Angels, and ''Space Hulk: Vengeance of the Blood Angels'' which focuses on the eponymous space marine chapter, they differ from the board game by being in RealTimeWithPause. The third one, [[RecycledTitle also entitled]] ''Space Hulk'' was released on PC/MAC/iOS in 2013. [[http://www.spacehulk-game.com/index.html Official Website Here.]]

The new adaptation called ''[[http://spacehulk-deathwing.com/ Space Hulk: Deathwing]]'', an FPS, is in development by [[VideoGame/EYEDivineCybermancy Streum On Studio]].

There is also a free game ''Alien Assault'', which was previously a fan-made ''Space Hulk'' adaptation which was more faithful to the tabletop game, but the copyright conflict with Creator/GamesWorkshop forced the creator to change the setting. But the game is mod-friendly, and the fans very quickly converted it back into the ''Space Hulk'' game.

[[IThoughtItMeant Has nothing to do with]] The ComicBook/IncredibleHulk ''[[RecycledInSpace In space!]]''. For that, see ''PlanetHulk''.

!!The tabletop game contains examples of the following tropes:

* ActuallyFourMooks: Genestealers start out as "blip" counters that are actually between one and three individual genestealers.
* AffectionateParody: [[http://www.newgrounds.com/portal/view/527363 Whimsical Tales of the Royally F%#ked]] and [[http://www.newgrounds.com/portal/view/611098 its sequel]].
* ArmorIsUseless: The Space Marines' huge, bulky, and ridiculously resilient PoweredArmor does absolutely diddly squat for them against [[AbsurdlySharpClaws Genestealer rending talons]].
* TheAtoner: Part of the Blood Angels' reason for trying to cleanse the ''Sin of Damnation'' is to regain the honor they lost when they spectacularly failed to cleanse another Space Hulk six hundred years ago.
* {{BFS}}: Sergeant Lorenzo's power sword, which appears to be approximately six feet long.
* TheCaptain: Sergeant Lorenzo and Sergeant Gideon. The Blood Angels' actual Captain, Raphael, serves as MissionControl.
* CaptureTheFlag: A few missions have the Space Marines trying to recover some sort of device or artifact. Played with somewhat in that the Genestealers can't pick up the "flag," and so must resort to killing all the Space Marines.
* ChainsawGood: Brother Valencio has a chainsaw ''[[PowerFist fist]]''. It's very useful for carving through bulkheads.
* ContinuityNod: The most recent Blood Angels codex has revealed that the original name of Mephiston, the chapter's Chief Librarian and all-around [[OurVampiresAreDifferent vampiric]] {{badass}}, was Calistarius. Hmm.... [[spoiler:Notably, Calistarius canonically survives the assault on the ''Sin of Damnation'', so they could definitely be the same person.]]
* CriticalFailure: A Space Marine's storm bolter has the potential to jam when fired on Overwatch. Brother Leon's assault cannon doesn't, as it's designed for sustained rapid fire; however, if he fires it for too long (IE, after having to reload it once already), there's a chance it will fail catastrophically and ''explode''.
* DoNotRunWithAGun: [[AvertedTrope Averted]] for Terminators armed with storm bolters, who may fire and move as a single action. Their armor is designed to absorb recoil from small arms and stabilize weapons during motion, allowing them to maintain accuracy while displacing.
* DropTheHammer: Sergeant Gideon carries a massive thunder hammer. Combined with his storm shield, this makes him one of the handful of Space Marine characters able to match a Genestealer in close combat.
* DungeonCrawling: Essentially a far-future equivalent of such fantasy adventures.
* EscortMission: There are several missions where only one Space Marine (usually Brother Zael, who carries the heavy flamer) is capable of completing the mission objectives, so the other Marines have to ensure that he survives and makes it to the target. Thankfully, Escort Missions are a lot less difficult when the VIP is a) completely under your control, b) a [[SuperSoldier Space Marine]] and sometimes c) equipped with a [[KillItWithFire heavy flamer]].
* GatlingGood: Brother Leon's assault cannon, capable of absolutely shredding incoming Genestealers.
* HoldTheLine: A few missions involve the Space Marines either surviving or keeping Genestealers out of a specific room for a certain amount of time: either until a specific number of turns have passed, or until the Space Marines have depleted the Genestealers' [[WeHaveReserves reserves]].
* HonorBeforeReason: This is a SpaceMarine saga, after all.
** The campaign backstory is a shining example; Honor is literally the only reason the Blood Angels set foot on the ''Sin of Damnation'' the second time. The entire Blood Angels chapter had been deployed to cleanse a space hulk, and their crushing defeat pushed them to the brink of extinction. [[CharacterizationMarchesOn Later fluff makes it clear]] that Astartes protocol demands that they avoid full-strength deployments, for that very reason, unless a chapter's existence happens to be at stake.
* KillItWithFire: Brother Zael's heavy flamer, which is critical for completing certain mission objectives.
* KingMook: The Genestealer Broodlord.
* LuckBasedMission: Frequently in older editions it could boil down to getting lucky with what was hiding under the Blip counters, especially in the frequently ''hideously'' difficult missions where the Marines had to shut bulkhead doors right in front of the board's spawn points.
* MoreDakka: A Marine on Overwatch can fire any time a Genestealer moves or performs an action in his line of sight, which can add up to dozens of times a turn if he's guarding a critical choke point. The drawback to this is that such rapid fire can cause his weapon to [[CriticalFailure jam]].
* OneHitPointWonder: Everyone, for simplicity's sake, though some characters have ways of making that one hit point harder to remove.
* PoweredArmor: The Space Marines' Tactical Dreadnought Armor ([[ArmorIsUseless for all the good it does them]]).
* PowerFist: The majority of the Space Marines are armed with these. Unfortunately for them, a [[MightyGlacier huge, cumbersome armored gauntlet capable of punching a hole in a tank]] really isn't the best weapon for swatting a [[FragileSpeedster fragile, fast-moving space bug]] that can rip your helmeted head clean-off your shoulders [[LightningBruiser faster than you can blink]].
* PsychicPowers: Lexicanium Calistarius, the Blood Angels' Librarian.
* PsychicRadar: The original edition of ''Space Hulk'' had expansion packs which introduced Librarians; {{Space Marine}}s with PsychicPowers. One of these powers was the handy 'Scan,' which allowed the Terminator player to reveal a blip of his choice, representing the Librarian using his telepathy to detect the presence of Genestealers.
* RandomNumberGod
* RespawningEnemies: Genestealer Blips.
* SchrodingersCat: Sergeant Lorenzo lives in the novella, but dies in the mission logs found in the Mission Book. The weird part? The mission logs are otherwise ''excerpts'' from the novella.
* SensorSuspense: This is a game mechanic, being heavily inspired by the ''Franchise/{{Alien}}'' series. Genestealers initially appear to the Space Marine player only as scanner "blips", each of which can conceal a variable number of the aliens (or possibly none at all). The number is only revealed when within sight of a Marine or when the Genestealer player decides to do so, whichever occurs first.
* {{Tagline}}: '''MAN VERSUS ALIEN IN DEADLY STRUGGLE'''
* {{Tearjerker}}: The ''Deathwing'' Novella included in the First Edition Expansion Rulebook of the same name.
* TimedMission: First Edition ''Space Hulk'' gave the Space Marine player a time limit of two minutes per turn, in an attempt to simulate the stressful and frantic nature of trying to clear out a bug-infested ghost ship; having a surviving Sergeant on the board upped this to three minutes, in addition to his other abilities. Second Edition dropped the mechanic, while Third Edition sort of plays it both ways: the timer is back, but it doesn't directly affect and is not affected by any other game mechanic, so it can easily be dropped if the players agree.
** Incidentally, because of the timer, "Overwatch" and "On Guard", it's generally accepted that a Space Marine player is going to make most (if not all) of their die rolls in the Genestealer player's turn.
* WeHaveReserves: The Blood Angels force on the ''Sin of Damnation'' numbers approximately 80 marines. Conservative estimates place the Genestealer population of the Hulk at around forty ''thousand''.
** Mechanically speaking, this is often ''necessary'' for the Genestealer player to win. A single Space Marine in a tight corridor can easily HoldTheLine... right up until [[CriticalFailure his bolter jams]] from being used to cut down [[ZergRush too many targets thrown at him in a single turn]] and the Genestealers overwhelm him before he can clear it. All the other Genestealers throwing themselves at him just serve to over strain his firearm.
* ZergRush: The Genestealers' primary tactic.

!!The videogames contain examples of the following tropes:

* AntiFrustrationFeatures: In ''Alien Assault'' the moves you ''really'' don't want to activate by misclicking (Thunder Hammer[=/=]Heavy Flamer self-destruct, Autocannon half-of-ammo consuming full-auto) are activated by holding their icon for a few seconds.
** Back when it still carried the ''Space Hulk'' name, it was an "Are you sure? Yes/No" dialogue box.
* CompetitiveBalance: With the arrival of Space Wolves as DLC and the announcement of at least one more future chapter, each chapter is being given tweaked stats to keep them from all being simple [[PaletteSwap reskins]]:
** JackOfAllStats: The default Blood Angels.
** CloseRangeCombatant: Space Wolves add +1 to their melee rolls (which stacks with any other bonuses) but only roll a d5 for command points instead of a d6.
** LongRangeFighter: One as-of-yet unnamed chapter[[hottip:*:though we're pretty sure it will be the Deathwing detachment of the Dark Angels]] is scheduled to bring special combi-weapons to the game. For those unfamiliar, these are special versions of boltguns with another, specialist ranged weapon glued to the top.
** Special biomorphs for the Genestealers were also announced, but we have yet to see how these will affect their playstyles.
* MonsterCloset: The first video game adaptation sometimes features Genestealers popping out of the walls - usually right ''behind'' one of your Marines. No sooner do you hear "Ambush!" then you hear the [[HellIsThatNoise death scream]] of the unfortunate Marine.
* POVCam: The first ''Space Hulk'' has five screens in the first person mode: a large, primary one for the Marine currently under your direct control, and four smaller ones for the rest of your team. You have to switch between the two sets when there are two teams present. The 2013 game plays from overhead view like the tabletop, but puts a grainy point of view frame in one corner of the screen, capturing the image from the pict-recorder mounted over each Terminator's over-built collar.
* [[RandomNumberGod Random Number God-Emperor]]: The 2013 game is a very strict adaptation of the tabletop rules, right down to rolling digital "dice" to determine results of actions and command points. Like the tabletop, this can make the game ''brutally'' NintendoHard, often to LuckBasedMission degrees.
* RecycledSoundtrack: ''Alien Assault'' reused some tracks from ''VideoGame/{{Battlefield}} 1942''.
* RealTimeWithPause: The first ''Space Hulk'' and ''Vengeance''.
* VideoGameFlamethrowersSuck: Completely [[AvertedTrope averted]] by the Heavy Flamer in the 2013 game: the only "standard" weapon capable of striking multiple foes with a single shot, it can spread down side halls/around corners/throughout rooms, and has the highest hit-chance of any Space Marine ability by virtue of flooding the entire area. It also continues to burn throughout the following turn for the Genestealers, allowing for a tactical withdrawal (or, preferably, the arrival of reinforcements). The only downsides are relatively short range (a "mere" five to six squares, and then spreading an additional five squares past that), it can't be used to Overwatch, and the fact that you can only fire six shots in a mission. Then again, few missions where you have the Heavy Flamer are designed to last more than six rounds, and filling a tunnel with fire is usually better than overwatch.
