McKool proudly presents the full version of The Mutant Factor, a single player modification for Crysis and Crysis Wars. This is a new single player campaign with a completely different story and a new set of characters. The Mutant Factor is heavily influenced by the Half-Life, Crysis, and F.E.A.R series of games. The player takes the roll of Phoenix, who is sent to investigate strange energy readings at a remote North Korean facility. While on the island, he begins seeing visions of his long lost daughter, Tara, which starts a cascading spiral between reality and possible insanity.After a horrific and bloody battle, he awakens to find himself trapped in an underground facility with only the voice of Dr. Marie Shepherd to guide him out....or is she the only voice? Ask yourself: Do you trust her?
