Dang, there were a lot of these kinds of games around! While I'm not a fan of the music genre, I do love zombie games! I thought it was really cool how this game was designed. Granted, I'm not that good at it, but still. It's interesting to see how everything comes together. The music is also pretty awesome by itself.
I found it weird how there was such a long prologue. Even the title is cool. Explosions are always good. I am really starting to recognize your animation. This is just a very fun game.
