Starting with the four initial powers, O'Connor learns new abilities throughout the game, such as teleportation across short distances, telekinesis to a limited degree, and the ability to pick up memory residue that introduces memories he can visit as if in a movie to find clues for the investigation. If O'Connor possesses a human he cannot be spotted by demons. When performed successfully, they will stop the search and leave after a while. If they spot him however, he needs to quickly shift between ectoplasm hiding spots in the environment to stay out of their way.

These roam various locations and O'Connor can execute them out by sneaking up from behind and performing a combination of keys and buttons. The other stealth actions segments are provided through encounters with demons. In these stealth sections O'Connor often needs to distract people using his presence and poltergeist actions to clear the way. They need to work together as Joy can manipulate the environment to help him. There are also side missions, not related to the story, where O'Connor needs to help out a fellow ghost move on to a next world by answering questions through gathering clues in the environment.Ĭertain parts of the game are spent with Joy, a little teen medium he meets early on, who explains the world to him and often acts as a sarcastic sidekick. Possessing people does not offer direct control over them, but provides control over their senses and mind-reading. Certain areas can only be reached by possessing a cat and sneaking inside. He has however access to a number of powers that allow him to influence people, eavesdrop on conversations, possess people directly and peek. Even though O'Connor can examine the environment, he is not able to interact with it directly. The player is allowed to make mistakes as it only leads to a lower ranking of the puzzle. After guessing successfully, the game moves on, usually to a new environment. To advance, he then needs to answer questions about the scene in the form of a puzzle, built up through the clues. Each location has a number of clues to discover, but only the crucial ones need to be found. Starting with his own crime scene, O'Connor needs to collect different types of clues to move on to new locations and progress through the story. Despite the freedom of movement the investigation needs to be done in a linear way.
