'''''Dead Space: Downfall''''' is a Direct-to-Video {{Prequel}} to ''VideoGame/DeadSpace'' set in the ''Franchise/DeadSpace'' universe. It goes into detail about what happend onboard the ''USG Ishimura'' and the state it is in when Isaac Clarke and the player reach it at the beginning of ''VideoGame/DeadSpace''.

The Red Marker is brought onboard the ''Ishimura''. Meanwhile the colony on Aegis VII is attack by Necromorphs. One of the colonists escapes with the corpse of his dead wife and heads to the ''Ishimura'', unaware that [[ZombieInfectee his wife is turning into a Necromorph]]. Onboard the ''Ishimura'', the Unitologists want to worship the Marker, and start to otherwise go insane.

The colonists ship crashes into the ''Ishimura'' and the Necromorph escapes, eventually making its way down to the morgue and inficting all the bodies down there. A team of crew members, led by chief of security Alissa Vincent, try to fight their way from the morgue to the top of the ship.

!!''Dead Space: Downfall'' provides examples of the following tropes:

* AccidentalMurder: Dr. Kyne's attempt to sedate Captain Mathius goes ''horribly'' wrong, ending with the Captain dying. The crew members (who had been restraining Mathius after agreeing with Kyne's assertion he was unfit for duty) wonder aloud whether or not it really was an accident; Kyne flees the bridge before he can be detained.
* ApocalypticLog: The log Vincent records explaining what happened on the ship.
* AscendedExtra
** Dr. Kyne played a fairly small part in the first game, but here he's treated more like a main character.
** Captain Mathius also gets a pretty decent amount of screen time before his death.
* AxCrazy: Everyone gets this from the Marker eventually, though some take longer to covert than others, and that assumes they live long enough to do so at all.
* BigDamnHeroes: Irons in the mess hall.
* BlackDudeDiesFirst: Averted. Pendleton may be black, and he may have gotten killed relatively quickly, but he's still not the first person of the FiveManBand to bite it. Hell, he's not even the first person in the ''movie'' to die on-screen.
* CallBack: At the very beginning of the movie, the first thing you see is the back of an engineer wearing the same suit as Isaac. It looks almost like a shot from the original game, complete with camera angle.
* TheCameo: Nicole has a non-speaking appearance, being rescued by Vincent with some other civilians.
* ClusterFBomb
* ChainsawGood: Irons uses a plasma chainsaw in a big damn heroes moment. As it's far more effective than their pistols, the security team trades up in kind.
* ConspicuousCG: The spaceships and some backgrounds.
* ContinuitySnarl: The movie timeline runs much faster than is implied to have happened in the game; the game's audio logs suggest the SanitySlippage took days to manifest alongside the Necromorphs. Other differences include the Marker being much larger and the Necromorphs being unable to approach it. [[spoiler: Though that may be because it has use for Vincent.]]
* ContinuousDecompression: How Vincent deals with the Necromorphs between her and the shuttle's emergency beacon.
* DownerEnding: Everyone is killed and the ''Ishimura'' is a death trap.
* EyeScream: In the games, you only saw a video log of it; in the movie, you get to watch Mathius get stabbed in the eye up close. Then it goes ''further'' into this when after he gets impaled in the eye, he falls onto the floor, driving it into his brain.
* FanDisservice: A young woman wearing only a towel is seen being stabbed and killed [[NippleAndDimed without the towel so much as coming undone]] (though we do get a brief PantyShot). What we do get to see is a fat man's fully uncensored penis.
** And before that, we get to see one of the Aegis VII colonists in her underwear. [[{{Squick}} While walking across broken glass, complete with a close-up on the shards digging into her bare feet]]. And that's not counting the bloody lacerations across her arms, legs, and torso. Or the way that she claws at her own flesh. Or her DissonantSerenity the ''whole damn time''. [[DrivenToSuicide Oh, and then she slashes her own throat with a laser pick.]]
* FiveManBand
** TheHero -- Vincent.
** TheLancer -- Hanson in terms of rank, though Ramirez fits the role too.
** TheSmartGuy -- Ramirez.
** TheBigGuy -- Pendleton.
** TheChick -- Shen.
** TheSixthRanger -- Dobbs.
* FaceDeathWithDignity: Samuel Irons. As the Necromorphs advance on him, with his plasma chainsaw no longer functional and his strength depleted, he simply takes his Unitologist pendant and recites a prayer before being hacked to death.
* FlippingTheBird: Vincent gives Mathius a salute with her middle finger, though his back is turned at the time.
* ForegoneConclusion: Even when the movie takes a few liberties with the plot, anyone who has knowledge of the game knows how this will end. Everyone dies and the ship is lost to the monster infestation. Even the opening scene lays it all out by showing Vincent's final recording declaring her the only remaining survivor.
* {{Gorn}}: Prerequisite for a ''Dead Space'' tie-in.
* GunsAreUseless: The security team's sidearms do precisely jack against the Necromorphs. [[JustifiedTrope Justified]]; the games establish that you need to cut limbs off to kill Necromorphs, which the security team doesn't know. Even then, their standard issue sidearms are woefully underpowered compared to the weapons you carry around as Isaac.
* HalfTheManHeUsedToBe: [[spoiler: Half the]] ''[[spoiler:woman,]]'' [[spoiler:technically. With a plasma chainsaw. Lengthways. Poor Shen...]]
* HeroicSacrifice: Both Irons and Ramirez know they're going crazy, so they go out fighting instead. Vincent gets sucked into space when she opens the docking bay so she can launch the emergency beacon on the shuttle.
* HighPressureBlood: Why don't the plasma saws cauterize wounds instead of this happening?
* HonorBeforeReason: Vincent's attempts to stop Kyne are intended to save the crew, who are ''rapidly'' being butchered by Necromorphs. Hell, by the time she gets to him, there can charitably be said to be ''maybe'' a dozen left.
* HowWeGotHere: The movie starts as Vincent is recording her log, then flashes back to how everything started.
* IdiotBall:
** Captain Mathius holds onto it pretty tightly. Then again, he ''is'' a Unitologist, and [[SanitySlippage going crazy]] on top of that.
** Vincent, too, who holds onto the hope that the crew can be saved long after it's obvious Kyne's got the right idea.
* IDontPayYouToThink: This is the response to one character pointing out that the Marker was obviously dumped on an otherwise worthless rock intentionally.
* IronicNurseryTune: "Twinkle, Twinkle, Little Star" comes up at the end.
* ItHasBeenAnHonor: Ramirez to Vincent.
* KillEmAll: Almost. Only Kyne makes it to the main game. Everyone else, including the protagonist, is dead by the end.
* LimitedAnimation: One of the common complaints about the film.
* MadeOfPlasticine: And that's not counting the instances where future weapons/tools are used.
* MaleFrontalNudity: The fat guy in the shower.
* ObligatorySwearing: The characters in the movie are a lot more swear-happy than the characters in the video game.
* OffModel: The health bars on everyone's [=RIGs=] are almost never consistent, let alone move down. Mathius' is a notable aversion to this, since we see his health meter quickly drop after the event listed under EyeScream.
* OhCrap: The patient from the mining colony gets one when he finds out the monsters from the colony have ended up on the ship.
* OnlySaneMan: Kyne (for a given definition of "sane"), and to a lesser extent Vincent. Both are the only two characters to remain completely rational throughout the film. Vincent gets a lower rank because she's a bit too GenreBlind for her own good (or that of others). She only comes to her senses after having sabotaged Kyne's first attempt, and by then it's too late.
* SanitySlippage: Affects some ''[[AxCrazy waaay]]'' more than others.
* ShamingTheMob: Samuel Irons breaks up an angry protest by the Unitologists on the ''Ishimura'' who're clamoring to see the Red Marker. One reasonable speech later, he's convinced them to improve the public perception of Unitology by not rebelling against the captain's orders and leave the Marker alone until they get permission to view it.
* TemptingFate: Lampshaded when Vincent remarks on Hydroponics seeming to be clear.
-->'''Ramirez:''' FamousLastWords.
* UnwittingPawn: Vincent ends up napping against the Marker, so it manipulates her into making sure more people come looking for the ''Ishimura''.
* VomitIndiscretionShot: Shen gets one after seeing the blood-covered mess hall and the dismembered corpses within.
* WeNeedADistraction: When they find a group of trapped civilians, Vincent brings this up since Slashers are blocking the door. Irons volunteers since he's starting to go crazy.
* WhatHappenedToTheMouse: Though anyone who played the game knows they're dead, the trapped civilians are never mentioned again after being rescued.
* YouGottaHaveBlueHair: Shen's hair is cyan, probably thanks to dye.
