From the back of the box:
Munchkins in Space!
The Munchkins are back--and they're in space! Now they're Mutants, Cyborgs, and Cat People... grabbing Lasers, Vibroswords, and Nova Grenades... fighting Fanged Fuzzballs, Bionic Bimbos, and the fiendish Brain In A Jar.
This is a complete, stand-alone game using the best-selling Munchkin rules (with a few new twists like Sidekicks). Yes, it CAN be combined with Munchkin! And, of course, it features the twisted humor of Steve Jackson and the wacky cartoons of John Kovalic. For 3-6 players (2 can play, but more is better). Playing time: about an hour.
Includes 168 Full-Color Cards!
