The Epic Experience You Cannot Miss – Las Vegas’ Signature Halloween Spectacle!

A research vessel went out on a routine deep-space mission and lost contact with home. What came back is not the crew that left.

On October 31st, you arrive as a witness to the aftermath. The room is the wreckage, half-lit by failing emergency systems, littered with the evidence of whatever happened onboard. The story doesn’t sit still on a wall. It moves through the crowd around you.

The guest list is the door, so secure your name on it now.

Event Overview:

Halloween Extravaganza 2026 stages Interstellar Nightmare, a fully immersive cosmic-horror world built across O-Bar and the O-Bar Patio at Otonomus Hotel. Atmosphere dancers, pop-up entertainers, and cosmic set design turn the venue into a single continuous set rather than a room with decorations added to it. The evening runs Saturday, October 31, 2026, from 8:00 PM to 12:00 AM, single night only.

The Headliner: Clejan, the Trap Violinist
Classical violin virtuosity collides with heavy-hitting trap and hip-hop. Clejan brings his national tour to Las Vegas, closing his West Coast run with a 45-minute headline set and then he keeps turning up all night, dropping into the crowd when you least expect him.

The Full Lineup

• Clejan, Headliner: a 45-minute set plus pop-up appearances through the night
• Stormie Andrews, Master of Ceremonies: carrying the night from welcome to crowning
• Pop-Up Entertainers: percussion, vocals, guitar, and horn talent building toward the Interstellar Jam finale
• Atmosphere Dancers: costumed characters working the full room as living décor
• Gio, Reigning Champion and Official Ambassador: back to defend his crown

The Costume Championship: Defend, or Dethrone.
Gio wore the crown in 2025. In 2026, it goes up for grabs again. Bring your best Interstellar Nightmare look, from zombie astronauts and alien parasites to cosmic witches and vampire robots, or impress us with an original idea of your own.
