Terror Vault 2026: SLASHED: Return to Hellville

San Francisco’s premiere haunted attraction returns for 2026 with “SLASHED: Return to Hellville” an all-new, bigger, and more terrifying theatrical and immersive experience from the insane mind of Peaches Christ. Thirty-seven years after the infamous Hellville massacre, a terrifying new evil has awakened. Step inside Terror Vault’s most ambitious immersive horror experience yet as you become trapped inside a living 1980s slasher movie. Journey through abandoned schools, haunted campgrounds, blood-soaked fraternity houses, forgotten video stores, and other iconic horror locations while confronting a masked killer, vengeful ghosts, and the terrifying legacy of Dr. Grieves’ Fear Engine. Featuring Hollywood-caliber sets, cinematic storytelling, live actors, and pulse-pounding scares, SLASHED: Return to Hellville is more than a haunted attraction. It’s a fully immersive horror adventure where every room is another scene, every shadow hides a killer, and every decision you make brings you closer to uncovering the mystery… or becoming its next victim.
