Running around chopping up zombies without a care can be fun. On those days when you don't want to think about what's happening in a game and just want to slash stuff up this can be the answer.
Unfortunately this game has some annoying flaws (a fairly useless map coupled with a maze-like second stage for eaxample).
Fortunately a remake is available called .Zombie Hunters
. The same game but with improved map, extra characters and extra costumes. Buy that one instead.
