In the hallways, labs and chambers of a shadowy compound, an unseen power is lurking. As a ghostly Spectral Operative, players must search for a physical body, which is mysteriously being kept alive somewhere in the enormous complex. Players won't always be alone though--as they explore, they must collect the energies of indigenous spirits to help unravel a mystery and build their own power. Some will help ... but beware, for not all the spirits are friendly. Prepare for a first-person adventure with a spectral twist!

* Explore the compound as a ghost, then possess more than a dozen unique character types using their weapons, equipment, skills, and even memories, to complete your goals. Possessions range from soldiers with guns to dog- and mouse-like creatures that can perform specialized physical tasks.

* Choose different characters and see the world in different ways.

* Travel through the human world virtually unseen, using your abilities to slip through cracks, interfere with electronics, move objects and more. Face challenges from two unique angles--as a possessed human or a lurking spirit hunting its prey.

* Prepare for death matches with the dead in all-new multiplayer modes that combine first-person combat with unique ghost and possession mechanics.
