Basic Play
Advance your character towards the top of the screen. Shoot and destroy the enemies, while avoiding their shots. Destroy the flashing prisons along the way to free the prisoner inside. When a power-up item appears, run over it to collect it.

The game consists of several rounds, and at the end of each is a wall barricade. Defeat the enemies that defend the barricade, then destroy the entrance when it starts flashing to clear the round and receive an additional Life.
