State of Decay, the open world undead action title, is in the final stage of certification and is on pace for a 5th June launch.
According to the developer's "I can tell you this: We don’t know the release date, and neither does anyone at Microsoft. But we do know the release process, and we can make some informed guesses about what that means for the release date. There’s no reason you shouldn’t know as much as we do — there are no conspiracies or big corporate secrets here — so I’m going to tell you what we know about how all this works.",
The developer went on to describe the entire Microsoft certification process, then thanked fans, "To all of you who have joined us in the past few months, and especially to those of you who have stuck with us for the past few years: Thank you, from everyone at the Lab. Your support and enthusiasm has helped us through the ups and downs as we wrestled this huge, awesome beast to the ground. And now we’re almost there."
