This game is a 1995 Destruction Derby clone. The main goal is to crush into opponents cars and make them spinning to earn points. Or you can simply destroy the cars or try to survive in the arena ! Like in the original game, cars deform and there is smoke and tire tracks everywhere !
Everything is pure C and OpenGL (all below OpenGL 2.0, mostly vertex arrays). Physics interactions are self made using a lot of dot products and squared distances. Car models are homemade using blender and textures using Gimp.
