Get psyched!

The world’s funkiest FPS is finally coming to Steam!

Open Fortress is a fully custom mod that builds on Team Fortress 2’s world-famous gunplay to create a smooth, stylish experience inspired by old-school FPS games. The Open Fortress experience is lovingly hand-crafted to ensure the best possible vibes, remaining true to the essence of TF2’s mid-century aesthetic while taking earnest inspiration from seventies action flicks. Featuring all new maps, all new guns, and an original soundtrack inspired by the funky tunes of the era.

Set several years after the Gravel War, Open Fortress envisions a new age in the Team Fortress universe. In the futuristic world of 1979, the heart of mercenary gunfighting has shifted from covert war in the Badlands of New Mexico to a worldwide free-for-all! Battle it out on a level playing field to seize weapons, power-ups, and a place on the podium from your foes!
