If you’re looking for Halloween thrills, Columbia has a haunted location that will rattle your bones. Necroplanet, located in an old meatpacking plant near College Avenue and Rogers Street, offers three attractions for $20.

“The Pit” and “Chaos 3D” are shorter experiences that, on average, rate 2.3 and 2.9, respectively out of 5 on the scare-o-meter. Necropolis Haunted House, the main attraction, leads guests through multiple rooms filled with top-notch special effects as well as a variety of characters ranging from crazed butchers to zombie mummies. On average, it scores a 4.3.

Tickets go on sale 20 minutes before the attractions open at 8 p.m. So, a word of advice: “Necropolis” is where it’s at. Skip “The Pit” and go straight to the Chaos 3D/Necropolis queue. Note that large groups will be split up to maximize the thrills, especially for “The Pit,” which can have up to a 1.5-hour-long wait. “Chaos 3D” and “Necropolis” are connected and may take two hours to get into, unless you spring for a speed pass ($27).
