Thirty actors are working the grounds at 9217 S. Eastern Avenue in Moore, Oklahoma, where Chamber of Terror is running four separate haunted-house themes through November 1, each one built to rattle guests more than once per walkthrough. Owners say actors aim to scare each visitor two or three times before they make it out, spreading the frights across a property that now includes a newly added outdoor section alongside its indoor attraction.
The attraction, located just south of Oklahoma City, is built around four distinct haunts: Piggy's Slaughter House, Sleepy Meadows Asylum, Burial Grounds, and Big Top Terror, according to The Oklahoman. Each theme is designed to provoke fear in its own way, with scares ranging from a gory doctor performing a lobotomy to chainsawed clowns and a nurse character who survived a string of failed surgeries, per the same report.
Pricing, Hours, and Who Can Get In
General admission runs $20 per person, while guests who want to skip the line can pay $35 for a fast pass, with tickets available both online and at the door. Anyone under 16 has to be accompanied by a parent or legal guardian, and hours vary depending on the date, so checking the schedule on Chamber of Terror's website before heading out is worth the extra step.
Industry-wide, tiered pricing like Chamber of Terror's fast-pass option has become standard practice. Survey data from ticketing platform HauntPay found that 78.4% of commercial haunted attractions now use VIP or skip-the-line passes to cut down wait times while adding a revenue stream for operators.
A Rebrand With Regional Recognition
Chamber of Terror didn't start out under that name. The attraction previously operated in the Oklahoma City metro as 13th Door Haunted House before rebranding and relaunching under the four-theme Chamber of Terror format for the 2025 season, according to OKHauntedHouses.
The rebrand paid off quickly. The site's 2025 Haunt of the Year award went to Chamber of Terror after the attraction had earned a nomination for the same honor in 2024, the directory notes.
Beyond Halloween Night
Chamber of Terror isn't shutting down the moment trick-or-treating ends. A single-night Blackout Night is scheduled for November 1, with $20 admission.
The venue has also pushed into off-season programming beyond its Halloween run. It hosted a Valentine's Day haunt called Broken Hearts, Bloody Promises on February 13 and 14, 2026, according to Texas Haunts.
A Billion-Dollar Season, A Risky Business
Chamber of Terror is operating inside a Halloween economy that keeps growing. U.S. consumer spending on Halloween is projected to hit $13.5 billion in 2026, with 74% of Americans participating and an average budget of $115.14 per person, according to the National Retail Federation. Nationally, the haunted attraction industry generates an estimated $300 million to $500 million annually.
That growth masks a brutal survival rate. Roughly 60% of commercial haunted attractions fail within their first three years, largely because of high startup costs paired with a brief one-month primary earning window each fall, according to research highlighted by Marginal Revolution. Analysts note that long-term survival in the industry typically requires evolving from a single walkthrough into a multi-attraction destination — a path Chamber of Terror appears to be following with its four separate themes, added outdoor section, and off-season events.
Attendance benchmarks from trade association America Haunts show that 80% of professional haunted attractions draw between 7,500 and 10,000 paid visitors per season, with teenagers and young adults aged 18 to 34 making up the core audience. Fewer than 3% of haunted attractions nationwide reach mega-attraction status with more than 35,000 paid guests in a season, the group reports.
Haunted houses like Chamber of Terror also face fire-code considerations.
