Not bad
I really like where this series is going. I preferred the first two installments- the progression from handguns to shotguns made it a little more exciting, and the only real addition to the gameplay I saw this time around was the fact that the player had an objective besides indefinite survival, and that there were NPCs. As much as I always wanted some final destination in the earlier versions, I think the desperation of knowing that it was a suicide mission, and the isolation of being trapped in one area against an endless wave of zombies, really added a lot of emotion to the experience. This just seemed like a really long level that I could basically just run right through.
I wish I knew a way to fix that, but if you can figure out some way to bring back that feeling, you'd really have a hit on your hands. (Obviously, it would have to come from the gameplay- the graphics are already top notch.)
I'll give it a nine, only because I'd give the last installment a ten.
