As a spectral operative, you must search for your physical body, which is mysteriously being kept alive somewhere in an expansive complex. While exploring, you must collect the energies of indigenous spirits to help unravel a mystery and build your own power. You can possess a variety of creatures from human soldiers to dogs. You'll see the world in different ways as you travel through cracks, interfere with electronics, move objects, and more. Be careful--while some spirits are helpful, others are not. Defeat evil spirits with an array of weapons, equipment, and skills.
