Maybe the best defense game I've ever played.
This game is just awesome. The zombie survival concept, though overused, was very well done in this defense game, and I like the uniqueness of the different zombies, with their speed and body armor and HP (fat = more health, haha), and the weapons were unique, too. However, I think more survivors would have been nice, as well as a greater variety of weapons. I would also say different locations, but since the story is that you're holed up behind your barricades that's not really important.
Anyway, great game. Looking forward to your next work.
