A first-person exploration game built around branching narrative choices and an omniscient narrator who reacts to the player's decisions. Players navigate an office environment, choosing whether to follow or defy the narrator's directions, with each choice leading to different story paths and endings. Originally released as a Half-Life 2 mod in 2011, it was remade as a standalone title in 2013 and later expanded with The Stanley Parable: Ultra Deluxe in 2022, which added new routes, environments, and endings across additional platforms.
