Undead Labs announces Lifeline is the name of the second expansion for State of Decay, their entropic open world survival/horror game in a concession to those who figure this out already (thanks GameSpot). The title is about all they are prepared to reveal right now, though they do confirm the add-on will also include one new map:

No, there is no final release date. We are just now digging into the internal playtest process (which is how our favorite stalkers players on Steam found out about the title a couple of days ago – with PC testing, we are playing using Steam, so we can experience it the way you do). 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? ;)
