Good game 5/5, i liked graphics, music and sound, and weapon balance, but it need some improvements, at first game survivors searching mechanic is too random, you need add chance (in percentages) to find something and risk, second zombies should attack your barricade or something, because idea that they just disappearing when they pass and do nothing is stupid, It will be cool if you can see survivors actually standing near by and shooting zombies. Overall good work, looking forward to your next games. :)
Well first game was very good, and second is even better. I think this will be first game on kongregate with 5 star rating. Rock music from bonus shop is awesome :)
