Okay, a few complaints...
1. The bullets don't go very far, which makes it kind of hard to turn the zombies into people.
2. You should be immune to your own landmines, snince people are smart enough to walk over them. I'm just saying, a zomb-dog came after, I lay a mine and ran, and the mine instantly killed me even though I was BARELy touching the explosion cloud. I can understand some health being knocked off, or stun, BUT INSTANT DEATH!?!? Sucky. You should also make more more survivors (or zombies) appear as you make them what you are. Instead of them turning into the opposite if you leave them. Over all, 6.
