Plot Edit

In the year 1908, A brilliant scientist by the name of Dr. Eric Chanikov, participated in a weapons project called the Death Ray, first developed by Nikola Tesla. The project back-fired, resulting in a explosion later known as the Tungunska Event. The results of the explosion somehow brought into existence, the Sigma Technology; a method that allows you to genetically combine two species together into one, Impossible creature. The disaster killed Dr. Chanikov's wife but miraculously his young son Rex, survived despite exposure to gamma radiation; but he was not unaffected. Dr. Chanikov later confided to his colleague Upton Julius, that he believes his son is the very essence of Sigma; having been combined with thousands of elements from his environment, granting him super human senses.

After the event, Dr. Chanikov fled persecution at the hands of the Russian government and exiled himself on a series of islands in the Variatas Archipelago. There, he continued perfecting the Sigma Technology, while his son was sent away to live a normal life in America; unaware of his abilities.

Twenty-nine years later; Dr.Chanikov contacts Rex in the form of a letter, instructing him to come visit him on his secret base so he can tell him the truth about who he really is. Unfortunately, he asked his colleague Julius to help with finding him; Upton decides to betray Eric instead, hoping to use his son Rex for his own nefarious purposes.

The Game starts with Rex Chance, former War Correspondent, receiving this letter from his dad whom he mistook for dead. Upon arriving at the Variatas Archipelago, he's unable to find his father and instead gets attacked by Julius and his horde of combined creatures. Rex is rescued last minute by Dr. Lucy Willing in her mobile Lab, a colleague of Dr. Chanikov and expert on the Sigma Technology. She tells Mr. Chance that she too is looking for his father and aids in the search.

They investigate a series of Isla's under Whitey Hooten's watch; Julius's right hand. From him they learn that Dr. Chaikov is in fact dead and buried. Rex Chance uses the Sigma creatures to defeat Whitey and vows to get revenge for his father's death.

Rex and Lucy set out to find Julius, making a quick pit-stop on Isla Aduro where they encounter Velika La Pette, a Parisian who has supposed intimate relations with Upton Julius. She attempts to stop them on his orders using her combined creatures but Rex defeat's her as well, rescuing the native villagers she had kidnapped.

Rex starts noticing he's feeling more aggressive, stronger with a keen sense of his surroundings; unaware that it's his abilities being awakened by his exposure to the Sigma creatures. This becomes even more apparent when they get stranded on Isla Perculsus and must fend off a horde of Julius's creatures. Here, Rex discovers he is able to control their Sigma animals without the use of combiner relays and is in fact communicating with them directly, much to Lucy's astonishment.

Later, they arrive on Isla Mutatio; where Julius's top scientist, Dr. Otis Ganglion, does his research. A former veterinarian who used inferior science to create his own spliced creatures via inhumane techniques. After seeing how the Sigma technology is being abused at the hands of Julius, Rex decides they need to destroy it. Lucy protests but changes her mind after discovering Ganglion had tested the technology on humans, killing them as a result.

The two plot to stop Ganglion by attacking his base on Isla Fervesco. After his defeat Lucy and Rex confront the Doctor but one of Julius's pets, a giant gorilla named King, kidnaps Lucy instead. Furious, Rex takes Ganglion hostage, threatening to kill him unless he helps him rescue her. Ganglion plays along in hopes of leading him into Julius's hands. Rex learns from Ganglion about his past as well as Julius's desire for world domination; believing Rex holds the answers on how to successfully combine humans with Sigma, creating men that could command Julius's armies at his will. After a failed attempt to ditch Rex on Isla Inasnum Rex follows him to Julius's base on Isla Tantus where the two men capture him. Because Rex is a Sigma creature himself, Julius attempts so use the combiner relays on him like regular Sigma animal; it almost works but Julius's creatures rally behind Rex and he's able to overcome the relay's control. Together, Rex leads the Sigma creatures into victory over Julius and they capture him.

Lucy escapes Julius's burning base unharmed and runs into Rex's arms for a hug. As Rex consoles Lucy, his eye's inexplicably turn white. The story ends with the cliff hanger, suggesting a possible sequel though none was ever made.
