Now a team of highly-trained super commandos including Rain, Alice and Matt must race to penetrate The Hive in order to isolate the T-virus before it overwhelms humanity. To do so, they must get past the Red Queen’s deadly defenses, face the flesh-eating undead employees, fight killer mutant dogs and battle The Licker, a genetically mutated savage beast whose strength increases with each of its slain victims.
