Just weeks before the release of Punch-Out!! for the Wii comes the unofficial release of the original NES game's Nintendo-aborted sequel, Mike Tyson's Intergalactic Power Punch. It's Punch-Out!! plus aliens, minus quality.

According to GameSetWatch's quick primer on the Mike Tyson's Intergalactic Power Punch, the game was originally planned to be a proper Punch-Out!! sequel, developed by Beam Software and published by Nintendo.

The game was not just a demonstration of Tyson's outer space boxing prowess, but also a showcase of the amazing ineptitude of publishers to generate capable follow ups to hit games at the time. The sequel removes both Little Mac and Doc Louis, replacing them with Tyson and manager Don King.

While the game was ultimately released without Tyson's likeness under the name Power Punch II, the original working prototype ROM for Mike Tyson's Intergalactic Power Punch has been released by a collector and no small investment from the community.

The ROM can be downloaded for free, thanks to their efforts. It can also be purchased in NES cart format, for extra authenticity/masochism. You can also learn much more about the game and its journey from prototype to product at GameSetWatch.
