Geist is a game unlike most FPS's. Most game time is spent switching between forms while solving puzzles and fighting off enemies. As a disembodied spirit, Raimi cannot generally interact with the physical world except through possession. He seems, however, to have some degree of mass and substance, as gravity still affects him (though he floats and can elevate himself for short periods) and he cannot pass through solid walls (chain-link fences are another matter, and he can slip through small cracks.) He is otherwise invisible and intangible, though other ghosts can see him and animals, particularly dogs, can sense his presence even when he's possessing something. When Raimi possesses an object, such as a dog food bowl, he sees things from the object's perspective even if the device has no visual apparatus. He is able to provide motive force on an ordinarily immobile object, activate electronics, and alter an object's appearance (for example, turning water from a possessed faucet red, or changing the reflection in a mirror.) Creatures can only be possessed when badly frightened or startled. Raimi sometimes gains glimpses of a host's recent memories immediately upon possession. Raimi has the same control over a host body that he would over his own, the only exceptions are an inability to make the host approach something which frightens him or her very badly and possibly speech (certain cutscenes seem to suggest than he cannot talk in a human body, though other game aspects indicate otherwise.) If a host is killed or destroyed, Raimi is unharmed and returns to his ethereal state. However, he cannot remain outside a host indefinitely; his spirit is continuously pulled towards the afterlife. Only by possessing an object or creature can Raimi "re-anchor" himself to the world, though absorbing life from small plants grants him additional time in this world.
Human hosts have no memory of what occurs when Raimi possesses them. They seem to recall only being badly frightened, and then suddenly being in a different room, possibly surrounded by carnage. The opposite goes for Raimi, where he actually gains memory from his host and can use this memory to find objects or places.
