I could never bring myself to purchase these rules because I hate the cover artwork so much... reminds me of South Park!

The cover art, and the rest of the art contained in the book are my only gripe, however the rules are solid, and the game play is fluid.
Character creation is fully customize-able, from a poor lackey caught out in the mix, to a super hero zombie killer, complete with followers (which must survive the game)
The scenarios are what drive the game, Always remember your mission objective! killing zombies if fun, but you can still lose the game by not fulfilling objectives.
In one game, all of our characters were dead at the end of the game, but we won because we met all of our objectives, it had a real bad movie ending feel to it!
Adversely we have slaughtered almost everything on the table, and still lost because we were an inch (or less) short of our objective!
If you have the opportunity, give it a try.
