Josh Knowles of Gaming Irresponsibly just found the game that Metroidvania fans have been waiting for on XBLIGs
"Do you enjoy retro gaming? Perhaps you like to call it legacy gaming, perhaps you simply call it the system that has lasted twenty years as you glare angrily at the third Xbox 360 console to have graced your TV stand. Whatever verbage you choose to employ the basic principle is that there is just “something” about the classic games of the NES and SNES days; something that has allowed them to have a longer shelf life than many more modern releases. Well the people at Heart Attack Machine Games clearly feel the same way, as is evident in their XBLIG title Parasitus: Ninja Zero."

"Parasitus: Ninja Zero (Developer: Heart Attack Machine) is a side-scrolling action game in which you battle zombie-like corpses, angry wolf/hyena type deals, and other interestingly perverse and difficult-to-identify creatures who are trying to make you dead. You’ll work your way through stages (which take place in different settings – castle, mountain top, etc.), and each stage has various levels. You’ll need to scale walls, wade through rivers, and dodge fireball booby traps as you face each stage and its peculiar inhabitants and bosses.
