Zoom in Space is a simple arcade-style shooting game whose pseudo-3D perspective and ship designs are both modeled after Buck Rogers: Planet of Zoom. Armed with simple twin-shot cannons, you move your ship vertically and side-to-side while enemies approach from up ahead to ram you. Only one enemy sprite can appear at a time, so the next attacker will only appear once the current ship has been successfully dodged or shot. Three types of enemy ships attack in a never-ending loop, and the game's only goal is to attain a high score by shooting down as many as possible before losing all three of your lives.
