Super Zaxxon is extremely similar to the original Zaxxon, running on identical hardware and having almost identical gameplay. Like its predecessor the game uses isometric projection, where the player can not only control the ship's left and right movements, but also adjust its height. Primarily Super Zaxxon offers slightly faster gameplay, a different set of graphics, different stage layouts and a few more enemies (including the "Mine Layer" in level 2, and indestructible turrets in level 1). The game is otherwise structured very similarly and has similar goals, but is considered to be the harder game of the two.
In the original Zaxxon, the player is confronted at the end by a large walking machine (called Zaxxon). In Super Zaxxon, it is three robot dragons, with Zaxxon not appearing in the game at all. There are also no space battles in Super Zaxxon, with all action taking place on an asteroid base.
Super Zaxxon is a much rarer game than its predecessor, and saw fewer ports to home systems. The game was brought to Apple II, Atari 8-bit Family, Commodore 64 and IBM PC (as a PC booter), and like the previous game, each version makes cutbacks due to the weaker hardware.
Many arcade Super Zaxxon cabinets exist as converted Zaxxon cabinets, and can be identified by a different cabinet design.
