* ThePlague: [[spoiler:Rundown 7 has a log describing that the NAM-V virus has wiped out one third of the population of the United States and is still raging, with the host of State of Truth encouraging people to abandon cities and hide in the wilderness]]. Its relationship to the sleepers is currently unclear. Further logs reveal that [[spoiler: NAM-V and a parasite called Parasitidae Garganta have evolved together as a symbiotic pair, and are responsible for creating the sleepers as well as the creatures seen in the other dimension. The parasites incubate NAM-V and NAM-V gives the parasites the ability to mutate their hosts into assorted monsters to further spread the infection. NAM-V by itself can also act as a more conventional virus even without the parasites.]]

** In [=R6D1=]: Nemesis [[spoiler:the Nemesis monster can only be hurt by shooting glowing tumors on its enormous surface. The monster is so tall the players have to climb to different elevations to get clear shots.]]

* ArtificialHuman: The mysterious "strangers" mentioned in some of the audio logs are indicated to be [[spoiler: vat-grown artificial humans (not copies[=/=]clones, more like a new species) created by Kovac as a replacement for its current brainwashed BoxedCrook program, due to being able to be manufactured much more quickly. Once you learn this, they end up playing no additional role in the plot despite the build-up they were given in prior logs.]]

* AlternateUniverse: [[spoiler: the Alt rundowns are heavily implied to be occurring in a parallel universe from the original rundowns. The Alt version of one of the final rundowns has your characters stumbling upon the corpses of alternate versions of two of your team members from yet another alternate universe.]]

* BolivianArmyEnding: [[spoiler: The Valiant ending in Rundown 8.0, which concludes with Schaeffer sending your team to the Valiant Chamber excavation and [=KDS=] Deep, only for you to discover it's a bombed out hole. Your team is then swarmed by endless waves of sleepers, including multiple Tanks if you somehow manage to hold out long enough. Death is inevitable, which leads to a unique game over screen that remarks on the futility of your efforts and then rolls the credits.]]

* BolivianArmyEnding: [[spoiler: Rundown 8.0's Valiant ending, which shows Schaeffer sending your team to the Valiant Chamber excavation and [=KDS=] Deep, only for you to discover it's a bombed out hole. Your team is then swarmed by endless waves of sleepers, including multiple Tanks if you somehow manage to hold out long enough. Death is inevitable, which leads to a unique game over screen that remarks on the futility of your efforts and then rolls the credits.]]

* BolivianArmyEnding: [[spoiler: One of Rundown 8.0's endings, which concludes the game's story, ends with Schaeffer sending your team to the Valiant Chamber excavation and [=KDS=] Deep, only for you to discover it's a bombed out hole. Your team is then swarmed by endless waves of sleepers, including multiple Tanks if you somehow manage to hold out long enough.

The ending fits with the game's overall theme of being a big middle finger to players and being intended for masochists.]]

''GTFO'' is a first-person co-op horror shooter developed by 10 Chambers Collective, a small 10 developer indie company founded by Ulf Andersson, who previously founded Overkill Software of ''VideoGame/PAYDAYTheHeist'' and ''VideoGame/PAYDAY2'' fame. Players control a group of prisoners sent down into a deep underground facility of unknown origin, by a mysterious entity called The Warden, to fulfill various tasks (such as recovering ID cards or starting a reactor). Complicating matters are the "Sleepers," strange humanoid monsters who are agitated by light and noise.

* CosmicHorrorStory: Latter chapters gradually push the story into this territory, [[spoiler: as the extradimensional nature of the NAM-V contamination (Sleeper infection) begins to show itself, and how in every single dimension it's present inside it becomes the dominant force over all life, with no known way to meaningfully fight back.]]

* CutAndPasteEnvironments: Much of the complex looks samey. Likely a deliberate choice to make unaware players get lost easier.

** The Titan enemies will continue attacking even after their heads are removed and their chests destroyed, much to the surprise of new players.

* SuspiciousVideoGameGenerosity: In general, whenever players get to a room that has a lot of resource lockers and resources, expect a gimmick where the player has to survive hordes and hordes of enemies while the player has to complete a different type of objective.

* SpeedRun: While the game is all about stealth, this hasn't stopped players from achieving this feat. In fact, the hardest level of the first Rundown for four people, can be done in only ''[[https://www.youtube.com/watch?v=Rkxsq7YobYA 13 minutes!]]''

* PermanentlyMissableContent: Once a particular Rundown event ends, its special weapons and level gimmicks are inaccessible for good.

* GuideDangIt: At no point are the game's many unique mechanics explained in any way in the game itself (which is pretty important, since beating a level is virtually impossible without knowing what's expected of you from the game itself). The only way to know how to play the game is to watch multiple videos on youtube explaining how to play.

* MeanBrit: Bishop.

* ArmorPiercingAttack: The HEL Revolver primary weapon and the HEL Gun special weapon can target groups of enemies if they're all lined up for a shot.

* BoxedCrook: Players are condemned prisoners who are being used as cannon fodder by the Warden to accomplish objectives inside the infested complex. [[spoiler:Logs the players can find describe that the Hydrostasis pods that store the prisoners also erase long-term memories, so it's unclear if the player characters actually committed any crimes...]]

* DugTooDeep: As revealed in some of the logs, [[spoiler:the complex is apparently located in a huge mining installation that stretches down 1.5km into the earth. Whatever caused the sleepers may have originated from deep underground.]]

* HellIsThatNoise: The rapid, throbbing heartbeat a Sleeper lets out if it detects movement. You have to stay completely still until it calms down or you risk waking up the entire room, so hearing it will definitely spike your blood pressure.

** Later logs and lore imply some are not made from human bodies, instead growing in cocoons or [[spoiler:walking in from another dimensions]].

* TheVirus: Revealed in the logs [[spoiler:the sleepers might be the result of a virus that was released after digging down into the earth past the 1.5km mark. Logs from Rundown 5 hint that the virus has already exploded into a global pandemic.]]
