The player controls a man who has penetrated the electrified Cybertron Fortress, in order to retrieve the priceless treasures within: golden keys, rings and bars.

Spinners (appearing on all levels) move blindly towards the player, but cannot harm him even when touching, unless he walks into them.

Cyberdroids (appearing from level 3 onwards) move in straight lines for a period.

The fourth enemy type is Spook, the ghost of a previous entrant to the fortress.
