Warzone 2100

The game is fully 3D. The game world is mapped by a grid; vehicles tilt to meet hilly terrain, and projectiles can be realistically blocked by steep mountains. The camera is free-moving and can zoom in and out, rotate, and pan up or down while navigating. Units can all be customized according to: chassis (which, takes weight and power into account); drive system (such as wheels); and mounted object (such as a weapon). Units can earn experience.
