A cold fog coils around the industrial shell of an old factory. The steel doors creak open. Inside, screams echo through the corridors as chainsaws growl in the dark.

That’s the welcome to Midnight Terror Haunted House, where owner and Oak Lawn native Justin Cerniuk has ripped up the old script and rebuilt one of Chicagoland’s scariest attractions for its 12th season.

Cerniuk, a Marine veteran who is self-taught in the haunting game, said his passion for scares started at home.

“I started with haunted houses in my driveway at the age of 10,” he said. “After a successful run of the same popular theme for several years, it was time for a new look, design, and approach to the way we scare.”

This year, the changes at Midnight Terror include a nod to the past.

“The haunt industry is bringing back that vintage feel,” Cerniuk said. Classic creatures of Halloween now take center stage alongside new horrors.

Visitors step first into Shadowtek, a decrepit industrial lab where Dr. Shroud’s illegal experiments turn factory workers into monstrous creations. From there, the haunt winds into Black Oak Grove, a mist-shrouded village haunted by vampires, werewolves, witches and mummies. The final test: a maze of killer clowns revving chainsaws.

Even the wait in line is designed to unsettle. The “Rotten Hollow” queue will feature costumed creatures, a street magician, jugglers, stilt walkers, dancers and photo opportunities — entertainment meant to keep nerves frayed before guests even enter the doors. “We’re so much more than just your average haunted house — we’re an entire event,” Cerniuk said.

The scale behind the scares is striking. Midnight Terror employs 120 actors, with about 90 performing each night.

“It’s almost like theater but more creative in a different route,” Cerniuk said. “We have actors from all walks of life, from athletes to theater students, and this brings everyone together. It’s a unique way for people to make friends.”

This fall, the haunt expands its calendar with special themed nights. Families with younger children can explore with lights on during trick-or-treat hours Oct. 25. On Nov. 2, “Blackout” plunges the entire haunt into darkness, forcing guests to find their way with only a glow stick. Nov. 8 marks “Clown Takeover,” a carnival of bloodthirsty jesters, and in December, “Christmas Fear” swaps yuletide cheer for yuletide terror.

The attraction has earned national recognition. TimeOut named it one of Chicagoland’s best haunted houses, USA Today and ScareFactor.com put it in their top 10, and ScaryOverload.com ranked it among the 10 scariest in the country.

Tickets start at $30 online and $35 on-site at 5520 W. 111th St. in Oak Lawn, with upgrades available for faster entry. The haunt runs through Nov. 8, with free parking and a shuttle service. Full hours, discounts and event details are posted at MidnightTerror.com.

“My favorite part is bringing everyone together,” he said. “Our goal is to deliver an unforgettable scare, the kind people talk about long after Halloween.”
