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.

Without providing details Undead Labs has revealed it is working on a new expansion for State of Decay:

We’re not yet ready to discuss features or make promises. All we can tell you is that it will offer you a new way to play your favorite survival game, that we intend to launch on PC and the Xbox 360 at the same time, and that yes, it will broaden your horizons by a few kilometers.

Fine, I’ll say it straight up: There’s a new map, okay?

No, there is no final release date. We are just now digging into the internal playtest process.

What if society came screeching to a halt? What if all our rules and laws no longer mattered? State of Decay brings these questions to life in a very real way. It’s not just about combat; it’s about doing what you must do to stay alive. Food, water, shelter, and ammo — you’ll need them all. Taking you beyond the initial panic, and beyond the first weeks of the crisis, State of Decay is the embodiment of the “What if?” zombie apocalypse scenario.

Move through the world like a zombie-slaying badass. Dive through windows, jump on cars, and take it to the living dead with baseball bats. Hop in a truck and mow down some undead pedestrians. Break into the local police station and clear out their arsenal or walk into the local grocery store to stock up on your favorite junk food. The world is your oyster…a shiny oyster that happens to be filled with zombies.
