SeaWorld Orlando has released its entire lineup of haunted houses and scare zones of the upcoming Howl-O-Scream, its after-hours, extra-ticket Halloween scare fest.

The event, which starts Sept. 6, will feature five houses  — four of them are new concepts —  and seven zones alongside five themed bars.

The houses include:

• The Ultimate Gamble, which is set in a casino with ghostly patrons.

• Water’s Edge Wellness Center, in which a SeaWorld news release urges visitors of “Seek the remnants of promised serenity … within its haunted halls, where the living and dead collide.”

•  Atlantis — Journey Below, set in an “eerie underwater kingdom.”

• Farm 51 with rustling cornfields and crash-landed extraterrestrials.

• D3LER1UM666 Laboratories, the lone returning house, which SeaWorld dubs a “fan favorite.”

New scare zones include Paradise Palms (roadside inn), Cannibal Harbor (cannibalistic mariners) and Seeds of the Coven (mystic forest). Returning zones are Blood Light District, Toxic Turmoil, Terrors of the Deep and Carnevil Pier.

Live performances include “Monster Stomp,” a Jack the Ripper-themed production, and “Siren’s Song,” featuring creatures who lure adventurers.

Two new Howl-O-Scream bar are named Sacrificial Spirits and Space Gate 3. Returning are Longshoreman Tavern and Tormented.

One-night tickets vary in price by date and are now on sale starting at $34.99. An unlimited admission ticket is now selling for $109.99, and a combo ticket that allows entry to one night at Howl-O-Scream at SeaWorld and one night at Busch Gardens Tampa Bay is $94.99.

SeaWorld’s Halloween Spooktacular, a daytime event with trick-or-treating and less horrifying themes, begins Aug. 31. It is included with regular SeaWorld admission.
