Battelle game engine is an open source project made on Blender 2.45 by Guillaume Coeur and Bertrand Lapraz in order to complete their bachelor degrees at the University of Geneva (CH). This project is supervized by Laurent Moccozet, teacher and researcher at the University. It uses "Bullet" physic engine (which is the blender game engine) for direct rendering.
"I am working on a project for my Bachelor degree at the university. It's one of our university's building in Blender Game engine.Â The project has to be finished in August (so i will put the .blend files around this date.)"
