How the action plays is a lot like Left 4 Dead, where staying together is key and zombie attacks can come any time and from almost any angle. The difference is that your progression is tracked RPG-style and the open world of the game allows you to take quests and complete them in the order you choose.Our hands-on play took place in Banoi Island's main city area, and we were tasked with traveling around a city square and putting up banners on billboards, presumably to notify survivors of where to go to find safety.
