, Are you brave enough? Underground: The Summoning horror event is set to test your nerves in a World War II bunker

This is not for the faint-of-heart or the claustrophobic. But if you love to be scared, this experiential horror event could be for you and your friends. Set in the historic Battlebox World War II bunker spanning 12,000 square feet beneath Fort Canning, Underground: The Summoning will be Singapore’s largest immersive horror experience.

Built in 1938 and recently reopened after a careful refurbishment, the historic bunker now serves as the stage for this event. Sign up for the nerve-wracking experience from Sep 25 to Nov 3. A collaboration between Super Productions, Battlebox Singapore, and Theatre of Wonder, Underground: The Summoning features interactive sequences, live theatrical performances, and mind-bending special effects.

The adventure promises a gripping narrative of soldiers beset by demonic rituals. Set in January 1942 with the impending invasion of Japanese forces, desperate British army officers turn to an ancient book of summoning for help. However, they unleash chaos instead as Bellum, the demon lord of war, and his minions overrun the bunker. 

The interactive experience takes guests in small groups of eight to nine people through a labyrinth of terror, where every decision will decide their fate. The intense horror-fantasy adventure lasts up to 45 minutes, and audience members will be challenged to defeat Bellum and the mayhem that has befallen the bunker by collecting hidden magical cards. The story unfolds as they make their way through a cavernous maze of multiple rooms and zones and must face their fears in order to survive.
