This Halloween season, when the living and the dead come closest together, Pseudonym Productions will introduce DARK PASSAGE, an enigmatic immersive experience exclusive to Philadelphia that opens Friday, Oct. 4, and is scheduled to run through Nov. 2.

Dark Passage invites its guests to step into a realm between life and death for a haunting evening of mystery and exploration, filled with Halloween-infused surprises and Instagram-ready moments. Beginning in the “Strange Spirits Lounge” (a pop-up speakeasy with cleverly themed cocktails), guests will step through a mysterious glowing portal and enter a story filled with surreal visuals, intricate sets and roaming performers, winding through a series of hidden rooms that hide secrets waiting to be uncovered.

Depending on their curiosity and sense of adventure, the attraction may take guests anywhere from 30 minutes to two hours to fully explore, with unlimited access to the Strange Spirits Lounge throughout the evening.

Dark Passage was conceived by University of Pennsylvania alumna Sarah Elger, who has designed theme park attractions for Disney and for Universal Creative, including Skull Island: Reign of Kong and Volcano Bay at Universal Orlando.

Dark Passage is located at 1004 Buttonwood Dr. in Philadelphia’s Callowhill area. Tickets are available beginning today on the official website. Online prices range from $35 for a single evening or $79 for a “season pass” valid for unlimited visits. Tickets purchased at the door range from $45 to $89, depending on availability.
