The United States has a military presence in two-thirds of countries around the world. A group of 12 have had enough and initiate a terror ultimatum called the Blacklist ~ a deadly countdown of escalating terrorist attacks on U.S. interests. Sam Fisher is the leader of the newly formed 4th Echelon unit: a clandestine unit that answers solely to the president of the United States. Sam and his team must hunt down these terrorists by any means necessary and stop the Blacklist countdown before it reaches zero.

Hunkered aboard a sturdy military ship and triumphantly homeward bound, Xian Mei, Sam B and the rest of their battle-weary crew are able, at long last, to breathe a sigh of relief ~ or so they thought. Sure, they may have quelled the wave of zombies that attacked Banoi in Dead Island, but they forgot one rule that governs the sea ~ beware the Riptide. Just as their rescue helicopter touches down to safety on the ship deck, a furious monsoon ravages the hopes of our unfortunate protagonists and steers them on a direct course toward imminent doom ~ in yet another zombie-ridden town. An undead uproar is on the horizon once more ~ and this time, the carnage and chaos promise to be more rampant than ever. Pack your suitcase and load your weapons for another vacation on Dead Island. Rife with all of the mutant-zombie mayhem of the original, plus unforeseen new plot twists, challenges and features, Dead Island Riptide drags you to an all-new danger zone in the town of Henderson. Once a luxurious watering hole for the yacht-collecting upper class and tree-hugging eco-tourists, Henderson is now a storm-soaked ghost town, where only wreckage and occasional boats remain. But this port locale on the island of Palanai is also your one last hope for survival. Rally together with the surviving members of the team and orchestrate an elaborate defense using traps, fences and turrets to keep your brain-eating foes at bay. This time, the battle gets up-close and personal as a master of hand-to-hand combat joins the team as a fifth playable character. Take control of John Morgan's powerful fists and brawl against zombies like never before. Plus, collaborate more wisely with allies using new and enhanced features in co-op mode.
