State of Decay Lifeline DLC Released, Video Available

Requires the base game State of Decay on Steam in order to play
Lifeline, a new DLC (downloadable content) for State of Decay, is available now via Steam and Xbox Live, Undead Labs announced. State of Decay: Lifeline puts you into the boots of Greyhound One, a military unit sent into a zombie-infested city to rescue the team of scientists who can put an end to the outbreak.
Lifeline features a new map, new characters, and a new way to play: you must defend your base against hordes of zombies, using the best military equipment and personnel your unit can scrape together.
