Note that I've never had the opportunity to lay hands on this obscure coin-op terror, so most of this information is second-hand. The player controls Sonic as he chases Eggman through the stars in a red spaceship. A flight stick on the left side of the control panel maneuvers the shuttle in any of the four cardinal directions, while firing and weapon toggling are handled by a pair of adjacent action buttons. A lever on the right side of the terminal can be used for a burst of speed, which also tilts the entire cabinet for some added immersion. At the end of each stage, Sonic must defeat Eggman in a giant boss ship. Succeed and a new weapon of celestial destruction will be added to your arsenal.
