GTFO, the new shooter from Payday lead designer Ul Andersson and his team at 10 Chambers Collective, has a release date. The game will release on December 9 at 12 PM PT through Early Access on Steam.

On Early Access, players will be able to get a taste of the first-person shooter that also features survival horror elements and team-based gameplay. You play as a prisoner trapped in a horrible world filled with nasty creatures trying to kill you.

The conceit with GTFO is a system called "The Rundown." This includes timed-based challenges that reset with new game updates, so players only have a limited window to take part. This sounds similar in nature to how Hitman's Elusive contracts work. Some missions, called Expeditions in GTFO, might be available for 1-2 weeks, while others may be available for months.

Take a look at the video below to learn more about how The Rundown works.

The Early Access period is expected to run for one year, during which time 10 Chambers will gather feedback and further tune and refine the game. For more on GTFO, head to the game's Steam page. You can also watch GameSpot's preview above, in which we describe the game as a fear-filled Left 4 Dead.
