Gravewood High is a debut stealth horror title developed and published by HeroCraft PC. Players navigate a shifting school building to uncover the mystery of missing students while evading a relentless antagonist. The title contains a single-player story campaign alongside an online co-op mode supporting up to six participants. In co-op, teammates solve puzzles or betray one another to secure a solo escape.
Mr. Hyde, a smart AI antagonist, tracks player movements, learns patterns, and develops new abilities to counter survival strategies. The school environment consists of fully destructible structures and randomized layouts that change between every session. Gameplay transitions through distinct historical periods, moving from the 1980s back to the American Civil War. Co-op sessions incorporate unique hazards like saw-filled ventilation systems and award performance-based titles such as Teacher's Little Helper. Shifting architecture ensures no two escape attempts remain identical.
