Blood Frontier

Blood Frontier is a Free and Open Source game, using SDL and OpenGL which allows it to be ported to many platforms; you can download it for both PC (Windows, Linux, BSD) and Mac. You can also obtain it through our subversion repository and live on the bleeding edge of development. The game is a single-player and multi-player first-person shooter, built as a total conversion of Cube Engine 2, which lends itself toward a balanced gameplay, completely at the control of map makers, while maintaining a general theme of tactics and low gravity. In a true open source by the people for the people nature, it tries to work closely with the gaming and open source communities to provide a better overall experience, taking all sorts of feedback from your average player, to your seasoned developer, aiming to create a story-driven game environment that is flexible, fun, easy to use, and pleasing to the eye.
