For a game that had awesome as one of its defining traits, Konami's Rocket Knight Adventures isn't exactly one of the Genesis' most well-remembered games. Shame. Maybe you'll remember this modern-day successor in its stead.
The retro revival streak at Konami has already spawned a handful of new downloadable releases: Gradius, Contra and (soon) Castlevania have all been given the "ReBirth" treatment. Konami will also be revisiting Rocket Knight Adventures, but in a different fashion.
