Awsome Game!
This is the best game I've played in a while. The dark cabin setting being lit up by muzzle flashes as you fight of zombies is really awesome. The zombies come from all sides and make you feel like you really have no hope.
I look forward to the zombie survival RPG, if it looks like this, but is bigger, it will be great.
My only problem is, if you run out if ammo, your dead. I know thats realistic, but you should be able to fight the zombies off with a knife or something. It should be hard to do, the knife shouldn't do a lot of damage, but it would give you some hope of scavenging more ammo.
In my game, I got the machine gun, ran out of ammo, and got backed into a corner and was eaten. Scary stuff.
