You are Alex Mercer, a shapeshifter with absolute mastery over your genetic structure, stalking the streets of New York City, searching for your past. Learn of viral research and hybrids designed to push the envelope of evolution — of America’s pursuit for the ultimate bio-weapon.

Face an ever-growing army of infected — creatures warped and changed by the virus. As it spreads, more and more of New York falls under its control. The virus overwrites a creature’s existing genetics; warping and changing their form into something else, something planned. As the virus gathers its army, rush to discover the secret behind it all; the one thing that can stop it before the city falls into ruin.

Against both of you is Project BLACKWATCH – an elite force of Army specialists ready to stop the spread of the virus at any cost. These operatives have seen it all before, and are eager to track you down and bring you in, dead or alive. They're even willing to execute the final solution in New York, if necessary. Their mandate is complete containment; even if it means everyone in New York must die.

Struggle to define what you will be – Man or Monster. Utilize your vast array of shape-shifting powers, your ability to consume and become any person you see, and your superhuman parkour-style agility to unravel the conspiracy and make those responsible pay. Push your powers to the limit, and unlock the genetic shackles that hold you in check.
