The Boiler Room is full of the undead; suspicious and possibly human meat is found in City Meats; a 5,000-square-foot clown and freak show is CarnEvil; and frightening activity takes place in the Twisted Tree Mortuary. Paintball, ax-throw and arcade games round out the fun in this year's SlaughterHouse, through Monday, Oct. 31. Shows are from 7 p.m. to midnight, Thursday through Saturday; and 6 p.m. to midnight, Sunday and Monday; $21. Visit slaughterhousetucson.com
