  • You are captain of the cargo ship Chromium B.S.U., responsible for delivering supplies to our troops on the front line. Your ship has a small fleet of robotic fighters which you control from the relative safety of the Chromium B.S.U. vessel.

  • Do not let ANY enemy ships get past your fighters! Each enemy ship that makes it past the bottom of the screen will attack the Chromium B.S.U., and you lose a fighter.
  • Use your fighters as weapons! Crash into enemies to destroy them before they can get past you. 
  • Strategic suicide is a powerful tactic! When the Chromium B.S.U. launches a new fighter, it releases a high energy burst which destroys all enemies in range. 
  • Self-destruct to preserve your ammunition! A double-right-click will cause your current fighter to self-destruct. Before the ship blows up, it ejects its ammunition so that the next fighter can pick it up.
