|Atari 5200 Super System|
∑ 2 versions exist! Parker Brothers originally agreed to have Roklan Corp do this port, but at the last minute decided not to use their version, instead programming it themselves (picture #2). However, they used a screen shot from Roklanís version on the box (picture #1)!
∑ BUG: If the last enemy destroyed is one of the three ships/satellites that you kill to receive your double-shot power-up, sometimes you wonít warp to the next level. The only way to warp is to let your ship be destroyed by a meteor.
∑ BUG: A rare glitch may appear in which 1 or more ships will remain on the screen (after shooting them) and youíll warp to the next stage. If you pass through the ship(s) while warping, nothing will happen.
