GTFO is a 4-player hardcore co-op action horror FPS. You and your friends will explore hostile and terrifying environments where, in an instant, you are thrown from edge-of-your-seat suspense to frantic action. It's a large-scale experience, testing players in their ability to gear up and adapt to an endless string of unknown and ever-changing challenges.

Every expedition in GTFO is unique and the game lets you make informed decisions on what equipment and weapons to bring - but even then survival is not guaranteed.

GTFO throws so many curveballs and unknown factors at you that you and your team always have to stay on your toes - and the atmosphere is suffocatingly tense. It's nerve wracking to play even for us developers! If you're easily scared, wear your brown pants.

GTFO was released for early access on December 9, 2019, before being officially released exactly two years later, on December 9, 2021.


GTFO is about a team of four people trapped in an underground Complex, kept there against their will, forced down into the depths to carry out different objectives for this unknown entity called the Warden. The underground Complex has been abandoned for many years and it's been overrun by flesh-eating, grotesque monsters, and you want to get out of there.

As you progress deeper into the Complex, the story will be told not only by the characters themselves, but by clues and hints found in the environment.

There are 4 playable characters in GTFO:

  • Hackett: An Irish native described as cynical and comical but reliable.
  • Bishop: A distrustful and pragmatic Englishman who is interested in getting the job done.
  • Woods: A thoughtful American who believes in deeper meaning.
  • Dauda: A determined and cunning but secretive Nigerian.

The dialogue system in GTFO is fluid and dynamic. Depending on what type of action and atmosphere players are experiencing, the banter between the characters will change reflexively.

GTFO players form a team of four scavengers who are forced to explore the vast underground complex while searching for valuable artifacts. Complicating the process is the presence of hideous monsters, who have overrun the whole area. The players must gather resources to survive, and work to unearth the answers about the past and how to escape.

GTFO requires teamwork to solve puzzles, and for finding items.

  • Hacking: Some lockers and doors can be hacked opened/to retrieve whatever is inside, like keycards, ammo packs, medpacks, etc.
  • Bioscan: Some doors require a bioscan for entry. All players present in the current play session must stand in the highlighted area.
  • Stealth: Although some of us might prefer to just barge in and slay the horrors rambo-style, it can be a tremendous waste of resources and there is no reward for this approach. If we assume ammo and health are limited, then triggering too many hordes will result in running dry and leaving us with only melee and low health. Therefore, quiet creeping might be the preferred method of moving through the Complex.
  • Engaging combat: Monsters will impede player progress to the next objective, but players should only engage them because they stand in the way or pose a threat to your ability to scavenge or complete the objective, not because the act of killing them in itself is rewarding in any way. Therefore, players should kill enemies in the most controlled way you can, such as a crouched approach with sledgehammer.
  • Progression: GTFO has no leveling system.

  • 4 player co-op: Invite friends or join a random group to face the nightmare plunge into the unknown depths of the Complex together.
  • Terrifying monsters: From split-faced mutant minions that eject tentacles to giants mutants, you won't be able to relax until it's all over.
  • Visceral gore: Popping heads of monsters with well-aimed shots can be bloody, but so is smashing mutant skulls with a sledgehammer.
  • Unique weapons and tools: A fast-firing smg with a large magazine is good for laying waste to the lesser minions, and for tougher, special monsters you can use the high-powered machine-gun. For the real fireworks though, set up a sentry gun or even trip mines to do the job for you.
  • Evolving storyline: Instead of a campaign mode to tell the story of the Complex and the Warden, the truth is revealed through a series of free post-release updates.
  • Teamwork and puzzles: More than focusing fire to slay the Horde, GTFO requires teamwork to progress through the Complex. Locked gates need keys or passcodes that can be acquired through coordination among the players to find and use.
  • Challenging encounters: The developers are focused on putting a lot of layered challenges in GTFO, and by mixing and matching these challenges (different enemies combined with different environmental hazards combined with different expedition objectives) they create interesting but difficult gameplay experiences.
  • Absolutely no P2W (pay-to-win) or loot boxes: Skill and teammates are all that is needed in GTFO, and there will never be pay-to-win microtransactions or overpowered weapons to buy.

10 Chambers released a screenshot showing a dark room with low fog. Spread around the room are approximately 25 enemy nest eggs or pods. Very similar to the movie "Alien". Some objects read "caution", possibly explosive fuel tanks to be used to clear hordes.

  • Ladders are easily climbable. Simply walk into it (or away from it) and the animation begins (or ends).
  • Enemies can breach doors with force.
  • Resource boxes contain various ammos and medpacks. Ammo packs can include standard ammo for primary weapons, special ammo for secondary weapons, and/or class ammo for tools.
  • Maps: The developers have created tools in order to to create levels more effectively, which then they personally touch up to make sure it's perfect for what they have had in mind.

  • Music Cues: Dynamic system that reflects what is currently happening. In stealth, the music is eerie and somber, but for a Horde onslaught, the music escalates to hectic and intense.
  • Enemy Cues: Atmospheric sound in games not only provide ambience in the environment for immersion, but offer clues as to what is happening and about to happen. The Horde rallying cry is well known, the Shadow scream is unmistakable, the squishy sound is a Scout's floating feelers, and the slithering crawler will hiss at your feet.


  • The replayability of the missions will be high, as enemy and loot spawns are randomized.
