From the announcement:
In Dead Meat: Quarantine Zone America™, two players assume the role of one of four diverse human factions. The tabletop game seeks to innovate the genre by changing the typical zombie game by pitting humans versus humans instead of humans versus zombies, as well as introducing new mechanics to encourage greater tactical decisions. Many of these systems revolve around the inclusions of zombies as an uncontrollable neutral faction that force tactical decisions and keep both players moving. In addition to these new gameplay systems, Dead Meat: Quarantine Zone America™ also features a rich history of the game’s world.
