I agree with most of the comments on here. Great concept, enjoyable for a short time. With more features and some better playability, this would be a great game.
On the farmhouse level I keep getting a bug while using the sawn-off shotgun. I can fire about 6 times, then it locks up. The game goes on, but I can't reload, switch guns, nothing. I can move around and aim, but no bullets! :D
Very fun game. I like to added survival aspects of this edition. Maybe in the next one you could make it so that ammunition is limited and needs to be searched for in addition to supplies and survivors. It would be hard, but more realistic. Heh. Realistic.
