3-D Cannon
3-D Cannon is a shareware game that uses 3-D polygon graphics with
texture mapping. Two players command stationary tank-like weapons that
sit on a fractal mountain and take turns shooting at each other. When
players shoot at each other the camera follows the bullet as it flies
through the air.
