GTFO, a cooperative survival horror FPS developed by 10 Chambers Collective, is currently on discount at Steam. In GTFO, you and three of your friends play as prisoners forced to explore the undergrounds around the Chicxulub crater, a place hit by the asteroid rain that wiped out dinosaurs 66 million years ago. You and your teammates must go in search of precious objects to respond to requests from a mysterious entity known as The Warden, while avoiding the hordes of monsters that have invaded the area. It’s up to you to find the weapons, tools, and resources to survive and hope to find a way to escape from this macabre prison. Navigate through the procedurally generated maps, work together to solve puzzles, and take part in high-intensity battles against the creatures that haunt the dungeons in this ghastly FPS.
