User Summary In Chromium, you play as the captain of the cargo ship Chromium E.S., responsible for delivering supplies to your troops on the front line. Your ship has a small fleet of robotic fighters which you control from the relative safety of the Chromium vessel. The game plays as a classic arcade game like R-type. You keep flying ever onward, while you shoot at everything that moves, in order to destroy them before they reach your mothership.
