Certain items in the PlayStation®3 system version of the Dead Island will only be obtained through this PlayStation Home event. Each week will introduce more levels and unlockable content including a premium PlayStation Home reward "Exploding Zombie Outfit" for players that pre-order Dead Island directly from Home's Central Plaza and the aforementioned "Exploding Meat", a powerful weapon for use in Dead Island that can only be acquired by surviving the PlayStation Home onslaught.
