GTFO is a 4 player action/horror cooperative first-person shooter for hardcore gamers looking for a real challenge. Players get to play as a team of prisoners, forced to explore and extract valuable artifacts from a vast underground complex that has been overrun by terrifying creatures. Gather weapons, tools, and resources to help you survive - and work to unearth the answers about your past and how to escape.
