Mike Tyson’s Punch-Out!! In Space Released 17 Years Later

By Alex Johnson | October 12, 2025

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 U31 Gaming 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.

Some games take a while to load on mobile, but once they start, the gameplay is smooth and exciting. I hope future updates improve mobile performance, but I still enjoy playing several hours a day.
