Open Fortress is a free and open-source Team Fortress 2 mod that aims to introduce new game modes, characters, story, and more to the existing TF2 universe. These additions, lovingly crafted by nearly a hundred contributors, build upon the iconic aesthetic of TF2, the gameplay features of other multiplayer FPS games, and the creativity and innovation of the Source engine modding community, with ideals of fun gameplay and maximum customisability at the fore.

Please note that the OF game and website are still under active development, with the game currently in an open alpha stage. However, you are welcome to play OF during its development using our current SVN-based installation method:
