Sparkster is finally returning to the gaming scene with Rocket Knight on May 12th on XBLA and Steam and May 18th on PSN.
Rocket Knight is the first release of the series since 1994. The adventure and visuals are all new, but it features the same classic gameplay from the original thanks to the 2.5D style.
Oddly enough, the SNES and Genesis titles have yet to hit the Virtual Console, XBLA, or PSN yet. Maybe we will see them soon to help promote Rocket Knight.
