GTFO is a terrifying multiplayer co-op hardcore shooter in which good teamwork makes the difference between life and death. The survival of a team of four players, composed of prisoners held against their will by a mysterious entity called "The Warden", depends on the team's ability to communicate, coordinate and manage their ammunition. In the trailer we see how the prisoners descend into the depths of the underground, with intense firefights and the sighting of a terrifying monster lurking in the darkness.
So far this year, we’ve released three major free updates for GTFO, adding new content and developing the story of the underground world of GTFO. With this Rundown update, prisoners will be sent deeper into the Complex and will have the opportunity to find out who they are and the story behind their character. says Robin Björkell, communications director at 10 Chambers. 'The search to discover who you are and why you’re here continues.'

GTFO uses a concept called Rundown, which consists of regular game updates that add new expeditions (maps, scenarios, enemies, etc.). These updates are free for all GTFO owners.
"Usually I say there’s never been a better time to buy GTFO thanks to all the new content added, and that the game is bigger than ever" says Robin Björkell. "But the fact is I’m advising everyone who still doesn’t own GTFO to wait until June 19. We’ve got a surprise in store for you!".
Rundown 5.0 Rebirth is now available free of charge to all GTFO owners.
