By all accounts this was a pretty fun shooter game...fusing the arcade and fps feel pretty well...my only real criticism is that sometimes it can get glitchy...like you keep walking when you've stopped pushing the button, or you keep firing, or the shield doesn't work etc...also I was annoyed by the fact there was no real PAUSE button on this one...oh and it was quite easy but never mind...still a fun experience, although I can't get over the idea of zombies using guns -.- i guess it's interesting but whatever
