From publisher blurb:
What's better than a free online generator? A generator that you can take with you wherever you go, with or without internet. A generator that lets you edit results, save them to a file, or print them directly. A generator that makes HORDES of ZOMBIES!
The Zombie Generator is a standalone version of the zombie generator at Chaotic Shiny, plus an all-new zombie image generator. Create hordes of ravening undead with the click of a button.
The generator is written in .NET, so it should work on all recent versions of Windows and quite a few *nix boxes and Macs as well (assuming you have an emulator).
