Inspired by the arcade game Centipede, Bug Blaster is a single screen shooter where you must destroy a Centipede that moves from the top of the screen. The Centipede moves across the screen and when it reaches the other side it moves down one place and moves back across the screen. You control a spacecraft at the bottom of the screen shooting the Centipede whilst moving left or right, as well being able to move forwards and backwards a short distance. Shooting the Centipede a number of times splits it into two and the other parts split into two when shot a number of times.
