Sandbox... zombiji... akcija.

S “State of Decay is an open sandbox world that develops in real-time, dynamically generating content based on your actions, the choices you make, and the ever-increasing zombie threat. Decide where you’d like to set up a fortified safe haven for you and other survivors you’ve rescued, then form raiding parties to gather resources and create supply chains. Use the materials you’ve gathered to develop your community as you see fit, but be careful – resources will deplete as you pillage areas, and zombies are attracted to noise and activity.”

“Take up the offensive by assaulting hordes before they reach your settlement, or focus on improving your defenses against the massed zombie attacks. Every choice and every action matter in this fully simulated, evolving world.”
