PERFORMANCE LINEUP

Watch your step! Wander into the parallel dimension of the "Hong Kong Paranormal Barrier" and you'll cross straight into Hong Kong's haunted urban legends! An eerie chill sweeps through as flickering amber streetlights reveal classic ghost-story horrors: paper effigies, Black and White Impermanence, Meng Po, Taoist priests and Chinese female ghost characters. You’ll never escape the local terrors lurking in the shadows! Simply interact with any of them to receive a limited-edition Halloween character card. Get them all to complete your collection! The roving NPC have reached a staggering 120+, double last year’s number with double the fun and photo ops!

Towering above the crowd, glamorous dancers transform into phantom spirits. Swaying and gliding to hypnotic music in a dazzling display of light and shadow, they take your excitement to new heights with every stunning move!

The "Hellbound Troupe" of paper effigies makes its spine-tingling comeback, busting out spooky dance moves with an endless stream of surprises, all in good fun on their way back to hell!

Under the Castle opens the door to its mysterious and lavish masquerade ball. Guests in Gothic gowns dance a dark waltz together, immersed in a haunting, seductive romance that resonates with the soul amid twisted classical melodies.

Zombies are swarming out, unleashing jaw-dropping spark stunts and pulling off high-difficulty moves that defy belief. Don't be surprised if one crashes right into your camera to give you the fright of your life!

The asylum alarm blares as deranged patients break into an all-out sprint. Dancing mad isn’t enough—they’re pushing their bodies to the extreme, unleashing pure insanity that will leave you shaking in both awe and fear!

The "Skelebration Fiesta" summons spirits and ghouls of every kind to join the daytime celebration, laughing and shouting in excitement! As night falls, the ghouls transform into skeletal terrors, pouring into the Park and into the crowd, inviting everyone to rave until the very end!

The "Spooky Live Band" rises from the grave to serenade the streets with soul-stirring tunes! They specialise in upbeat rhythms, moving the hearts of the living and the dead alike.
