Great!
What a great game! I do admit the survivors were kind of pathetic.. once in awhile they pulled off a decent headshot. Just add more zombies for each survivor, and make the survivors shoot better.
The main thing I didnt like though was if I'm aiming at the head of a zombie at the bottom of the screen, many times it would just shoot a zombie a little higher in the legs. So I'd end up killing the zombies from top to bottom, or using shotguns at lower enemies. Otherwise, great game! Hope there's a second. Where zombies can maybe swipe at you if you are too close to the gate because I noticed you can back up, but no point in backing up.
