Dead Island: Riptide (Xbox360)

Furious monsoon rainstorms have laid waste to the island of Palanai in the Banoi archipelago. Waters have risen and caused a flood disaster ¿¿ because of this and the raging zombie invasion, a rescue mission for the survivors seems to be without prospect of success. All hope seems to have been lost for the surviving humans¿¿
About Dead Island Riptide:
With invigorating new elements infused into a proven mix, Dead Island Riptide will reanimate the zombie terror in the original game. A monsoon has hit the once beautiful archipelago and heavy rainstorms have laid waste to large areas of the islands. The city of Henderson and jungle areas on the island of Palanai were flooded leaving boats as the only remaining way of transportation. Dynamic weather conditions will force the team members to adapt to changing visibility conditions.
A fifth character will join the team, with an all-new and unique skillset. The combined skills of the group will be sorely needed, since terrible, new and unknown zombie mutations have emerged all over the island.
In new hub defense missions the coop teamplay skills of the survivors will be tested to the limit ¿¿ they need to strategically place traps, fences and turrets to fend off oncoming Zombie onslaughts and to protect the humans in these sanctuaries.
New communication features in coop mode also allow players to enjoy an even more intense and strategic teamplay experience.
