Murdered: Soul Suspect

The game requires the player to investigate in a linear way, starting with O'Connor's crime scene and collecting clues to progress through the story. Each location has several clues to discover, but only the crucial ones are needed. The player must answer questions about the scene by solving puzzles built up from the clues. While making mistakes won't hinder progress, it will lower the ranking of the puzzle.

O'Connor can examine the environment but cannot interact with it directly. He has access to powers that allow him to influence people, eavesdrop on conversations, possess people, and peek. Possessing people provides control over their senses and mind-reading, although not direct control. There are also side missions where O'Connor helps a fellow ghost move on by answering questions through gathering clues.

The game features a young medium named Joy who explains the world to O'Connor and acts as his sarcastic sidekick. In stealth sections, they work together to distract people using O'Connor's presence and poltergeist actions. The player also encounters demons that roam various locations, which can be defeated by sneaking up from behind and performing a combination of keys and buttons.

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. There are 242 optional collectibles to collect, including nine sets of artifacts and eight sets for all the ghost stories.
