Penetrator

You are about to be sent on a mission through treacherous enemy territory. As commander of the Penetrator, one of the most powerful and advanced ships yet developed, you will travel through torturous landscapes and tunnels on your hazardous expedition. To complete your trek and accomplish your mission, destroy the enemy neutron bomb installation or face certain death against the impassable canyon walls beyond. Once you are able to destroy the installation, return the way you came for yet another (and more deadly) mission.
