Current Version: v0.80 (Beta 1) released 24th February 2009

Blood Frontier is a Free and Open Source game (see our License), using SDL and OpenGL which allows it to be ported to many platforms; you can download a package for Windows, Linux/BSD or Mac OSX, or grab a development copy from our Subversion repository and live on the bleeding edge.
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. For more information, please see our Wiki.
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.
