Willis is a diver that is trapped inside a water tank. The player has to free him before Willis’ oxygen runs out. The only way to free him is by pushing the red buttons placed inside the tank, and to do so the player must fire a cannon to cut the wires that hold these heavy wrecking balls. The wrecking balls are the only objects that are heavy enough to push those red buttons. Once all of the red buttons are pushed, Willis heads to the next water tank until he is finally free and safe.
