A team of navy seals investigating a series of strange reports from Soreo, a desolate volcanic island somewhere in the Pacific, have gone missing. Kurt Robinson and his team are sent out to reestablish contact and to find out just what truth is behind those reports... Bit by bit, the history of the island and its inhabitants will be uncovered - as will Kurt Robinson's role in it.
Vivisector: Beast Within is a first-person shooter which has players exploring some thirty-odd levels ranging from beaches and jungles to the snow covered heights of an inactive volcano. They'll be forced to face a literal army of various engineered animals, from canines with lightning rods on their backs and metal reinforced fangs to the Rhino-truck, to various half-breed like Gepardmen, which utilize Ninja-like mortal combat techniques, or various types of Wolfmen, which field different types of heavy weaponry.
The player, in turn, gets access to an arsenal ranging from a standard combat knife and Pistol to more advanced weaponry, such as machine guns, plasma rifles, and a handheld Howitzer.
In the German version, all blood and gore effects were removed and killed enemies disappear almost instantly. Also two sources for experience points were removed: "Vivisektor" (knife kills) and "Fatality" (awarded for spectacular kills). A detailed list of changes can be found on schnittberichte.com (German).
The working title for the game was Vivisector: Creatures of Dr. Moreau as it was partly inspired by H. G. Wells' famous 1896 novel The Island of Dr. Moreau. The events of the game are set 100 years after those in the novel, on the same island and still feature similar experimental human-animal hybrids. The game also has a similarly named renegade geneticist: "Dr. Morhead", whose hybrid soldiers are fighting against the corrupt general that ordered their creation.
