Extreme gore, which is more than most R titles carry. Beyond that, real scares and several jump scares.
How we rate: an AI reads what is known about each title and tags it 0 to 3; we check the tags against a hand-rated set and correct them by hand when readers tell us. Estimates, not a scene-by-scene review. Spot a mistake? Tell us.
