Dead Island Riptide picks up right where the original game left off, with the same four survivors, Sam B, Xian Mei, Logan Carter and Purna. Because of a tropical storm the chopper crashes. The crew land on a military ship where, due to a raging monsoon and the fact that our survivors are infected, an all-new zombie outbreak occurs onboard. This forces players to flee the ship or the ship runs aground (media reports are conflicting).
