FUN!
I originaly saw this game on a show on G4 (Attack of the show) or a copy of this game but this game is much better then i thought i was when i watched that show.
I love the graphics and how the background color changes every another level.
And i really like how it's not how about how many times you shoot them but where you shoot them (even know pumping 10 bullets in a zombie will kill it quite fast :P) I wish that how zombies shot them up games were as good as this.
