45 minutes

Up to 45 minutes of immersive theatrical horror unlike anything you have seen before!

It is January 1942 and the Japanese invading force is getting closer and closer. The British army is overwhelmed and out-maneuvered, and the Fortress that is Singapore will fall… unless desperate measures are taken.

In a desperate cry for help, the team of commanding officers turn to dark forces – a book of summoning, an ancient ritual.

But chaos is unleashed instead because Bellum, the demon of war, is unpredictable. And his minions too are bloodthirsty. These bringers of deception, grief, violence and mayhem – all the horrors of war, demand sacrifice. They want flesh and they want souls.

Witness the mayhem as the bindings are broken and the demons sweep through the underground bunker – each playing their twisted games and exacting the terrifying price from the humans who dared to summon war!

Underground: The Summoning is an immersive theatrical horror adventure brought to you by the creative minds at Super Productions, event partner Battlebox Singapore and theatrical stagecraft specialists, Theatre of Wonder.
