By the will of fate, in the midst of a zombie apocalypse, you took refuge inside the tree house. But every night the number of zombies increases, and the food for them becomes less and less. The walking dead hordes are not averse to regaling with your brains, and no shelter will become an obstacle for them. In order to repel the armies of zombies, you have to assemble a group of survivors, arm them and accumulate enough ammunition with supplies. Build animal traps, rainwater filters, defensive fortifications, spikes and saws to kill infected zombies, craft bullets and upgrade weapons. Go to raids in wasteland, share resources with your neighbors, meet new survivors, collect abandoned resources and supplies. In addition to undead zombies, you can meet friendly groups of survivors or gangs of marauders. Surrender, attack, or rob - you decide.

Choose the style of defense that suits you best: targeted sniper rifle shooting, random automatic rifle fire, or support with shotguns. Will you sacrifice a squad when meeting with looters or will you pay a pass fee? It's impossible to save everyone!

Strategy and strict calculation is the key to success! But be prepared for the gifts of fate. At any time, your teammates can leave the group, taking with them a large part of the supplies. The bitten ones can hide their condition until the last moment - as a result, not only they, but also other members of the group may suffer. Wild animals can take away part of the supplies, inept handling of fire can lead to the loss of part of the ammunition... But there will be time for pleasant events. Isn't it nice to live just one more day?
