The player is set in the role of an anonymous ninja, tasked with getting into a warehouse to steal a floppy disk which has the names of rebel leaders on it. The player must navigate through the complex of rooms (consisting of the warehouse, dark tunnels and the secret command centre) to find the disk and escape. The player has an energy bar which is depleted by falling too far, crouching under water or being attacked. If the energy bar is completely depleted or if time runs out, the game ends. The bar can be replenished by standing still and resting in a safe area.
