After GEI (Green Earth Initiative) Successfully released a biological altered virus into the air, as well as infecting dogs and volunteers, the world is plunged into chaos. A lone family, taking shelter in an Atlas Survival Shelter and a U.S. Marine Infantry Regiment, alone on a cruise ship with their family members are all that stand between GEI trained killers, known as Purifiers and total destruction of what is left of humanity. But none of those still alive, knew that the Resurrected (those who came back from the dead) would be a game changer, for all sides concerned. While isolated pockets of uninfected try to stay alive until help arrives, the Resurrected become more organized and deadlier as their insatiable hunger forces them to attack anyone and everyone who crossed their path. Now its Purifiers against U.S. Marines, Survivors against Resurrected and when all sides meet, the results will be explosive and deadlier than the plague all by itself could have ever produced.
