Mars Massacre is a free and open-source first person shooter. This is a total conversion of Sauerbraten with Tesseract Engine, including dynamic lighting, HDR and SSAO. Mars Massacre contains high-quality textures and soundtracks, realistic particle effects and new animated 3D models, therefore taking full advantage of this new version of Cube Engine.
PS: An English translation will be released with the next beta version (coming in a few weeks). So, don't worry English people ! I hope not to make too many mistakes. ;p
