Fear Overload Scream Park is a seasonal Halloween destination in Newark, California, featuring two immersive haunted houses under one admission. Its 2026 lineup includes Serial Killers: The Harvest, an industrial slaughterhouse filled with machinery, violent characters, and gruesome environments, and Greyhaven Hospital: After Visiting Hours, a condemned medical facility populated by sinister doctors, nurses, and unwilling patients. Both attractions emphasize elaborate scenery, live performers, loud effects, darkness, and close‑range scares.
Special event nights transform the experience by sending guests through darkened corridors with only a glowstick for guidance. Visitors can also purchase a Respawn Pass to repeat both attractions and browse an on‑site shop offering apparel, collectibles, and themed merchandise. Located at NewPark Mall with free on‑site parking, Fear Overload is designed for thrill‑seekers and is not recommended for children age 12 or younger.
