Good Fun
This is a good fun game. The artwork and sprites are very nice which is something you don't see often.
My criticism would be that most of the weapons are too similar and that one of them is FAR too powerful and I'm not talking about the hunting rifle.
The Chainsaw friggin kills everything and you get it quite early on. IMO everyone should have this as their secondary weapon. Even the army men take about two seconds to ventilate.
Also it would be nice if ammo ran out. It takes away from the scair-factor if you know you've got a couple extra million clips in your pocket. It would be nice if the ammo could be searched for as well as the weapons.
The diary was a brill idea make sure you get to look at every day!
Strategy for players: Make sure you have maximum amount of people at all times. I recommend even if you have the maximum amount of survivors have at least 2 hours looking for them to make up for lost numbers. However once you get the secret weapon only repair barricade (if you need to). If nobody is leaving the barricade in the day then nobody can get lost - logic.
Best Combo: Chainsaw+Hunting Rifle.
