State of Decay developer Undead Labs has revealed in a new blog post that the title has reached more than one million sales since its launch back in June. The large number is inclusive of both the original Xbox 360 launch and the currently in-development Steam build which went live last month.

As we said at the half million mark, we are humbled by your continuing support and enthusiasm for the ideas in State of Decay. Your encouragement drives us to keep working and keep improving. You got us here with your energy, your feedback, and your telling your friends about us. We thank you from the bottom of our hearts and brains.

The developer also stated that development for the title won't stop, with current work being done on both the PC version and a new DLC pack named Breakdown. According to TenTonHammer the new DLC will feature "new Heroic Characters, additional weapons, and the new Survival Mode to the game."

Those wanting to try their luck at winning a copy of the DLC for free can head over to the Undead Labs website and post your favorite memories from State of Decay’s development or in-game experience.
