The first Dead Island wowed zombie fans with its sad and unconventional CG trailer. Publisher Deep Silver and developer Techland are back to build hype the same way for the brand new, full retail sequel Dead Island: Riptide. In addition to the new trailer, we now know a fifth character will be joining the returning cast.

Dead Island: Riptide takes place on another island in the same archipelago as the original Dead Island. The game features a renewed focus on co-op, allowing players to team up regardless of level. Four players will team up to defend safehouses against waves of zombies during the campaign, delivering Horde mode-like chaos. Details are scarce on the new fifth character, but Deep Silver says he'll have a unique skill set.

Dead Island: Riptide hits 360, PS3, and PC in 2013.
