The Hostel director is hoping the Goretorium attraction in Sin City will become a ""world Mecca for horror fans"".
He tells Deadline.com, ""Horror fans know that with my name on it, it won't be for little kids. They know it will be a very scary experience.""
The multi-storey haunted house isn't the first time Roth has taken pleasure in give horror fans a real life scare - he has had huge success with the Hostel: Hunting Season maze at Hollywood's Universal Studios.
A franchise is already expected for Goretorium, with plans in place to open branches in London, Tokyo and New York.
The Vegas venue will open in September (12).
