Zombie Forest

You find salvation in a house on a tree in the thick of a forest lousy with living deads who are not averse to treat themselves to fresh brains.
As you progress through the game other survivors join you, you can improve your weapons, create new buildings, barriers, traps, exchange resources with your neighbors, send brigades to raids to look for survivors as well as resources and weapons. But not everything in the garden is rosy - you have to combat hunger and thirst, lack of resources and bullets, see your partners die and miss and the number of zombies is increasing all the time... How long will it last out? Is death inevitable!?
