A game similar to Moon Patrol, but instead of being set on The Moon, players control a time-traveling vehicle that transports them to various battlefields throughout history. Unlike Moon Patrol, every level has a different set of enemies with slightly different behaviors, and a different musical track to fit the current era.
Otherwise, the mechanics are similar to Moon Patrol, with firing both up and forward, jumping, and controlling the pace of the vehicle, with the vehicle moving quicker and gaining more points toward the right end of the screen, but driving more safely toward the left end. Enemies attack from both the sky and on the ground, which players must either avoid or shoot.
At the end of the level progression, a boss has to be defeated before the game loops.
