Altercation is a game based on some elements of Combat and Asteroids. The player controls a tank that when hit splits into smaller tanks, all controlled by the same input. Smaller tanks of the same size can merge again. Tiny tanks are fast and harder to hit, and better for stealth maneuvers, but more challenging to control. Large tanks are slower and an easier target, but merging reduces your total number of simultaneous bullets but raises your total HP.
