Awesome and addictive.
Overall a fun game, no glitches that I've seen except that I have trouble saving it (meaning that it won't save at all)
Graphics: The blood makes it harder to see the later enemies in the game.
Style: This has been done many times before but it seems to have a different feel than the other games.
Sound: Really monotonous, I just play music over it, but I guess it can't be helped.
Violence: Zombie game + Shooting+ Blood = Violence. :P
Interactivity: The experience system was well adjusted for the strength of the guns and powerups.
Humor: Hey, I think killing zombies is humorous.
Overall: Good game if you like violence, and who doesn't?
