From the update:
New release from Frontline Games - One-eyed, one-horned, flying PURPLE PEOPLE EATERS!
Look out for the Purple People Eaters! These hungry aliens will gobble you up and spit you out...literally. If you’re looking for a free one-way trip to the alien space ship, you can hitch a ride inside one of these creature’s bellies, but we wouldn’t recommend it.
Genetically modified and mind-controlled by “The Grays” to hunt down the "flesh bags" and be live human transporters, the Purple People Eaters are definitely to be avoided at all costs...good luck!
"Purple People Eaters" is an expansion set for "Alien Attack!" A copy of the "Alien Attack" rules is required to play the expansion.
