Similar in premise to the arcade classic Defender, each level in Orbitron takes place in a single looping sector. In Countdown Mode, players must fight off increasingly difficult waves of enemies, as in Defender. The game also includes a defense-oriented Guardian Mode, along with the survival-based Extra Mode.
Orbitron: Revolution earned a semi-finalist spot in this year's Dream Build Play competition alongside other XBLIG standouts like Oozi: Earth Adventure and ENGO. Orbitron is priced at 240 Microsoft points ($3).
