Electricity at the World’s Fair, on the set of the new virtual-reality adventure “Nicodemus” in Las Vegas.

The demon Nicodemus is on the loose in the old fairgrounds of the 1893 World’s Columbian Exposition. That is, if you are inside of a new virtual-reality attraction in Las Vegas.

The VOID at Grand Canal Shoppes in the Venetian/The Palazzo resort (3377 South Las Vegas Boulevard) in Las Vegas has opened an immersive walk-around adventure game called Nicodemus Demon of Evanishment, based on the 1893 World’s Fair. The describe the attraction this way:

In the summer of 1893, the World’s Columbian Exposition – aka the Chicago World’s Fair – was held on the south side of Chicago. Three days before the fair closed, a tragic demonstration in the Electro-Spiritualism Exhibit brought something terrible into our world.

Word spread that an unknown creature was luring guests down to an ‘Evanishment Room’ … from which they never returned. The attractions were quickly and quietly closed. Workmen refused to dismantle the exhibits as the fair died around it. Two months later on January 4th of 1894, strange lights were seen coming from the abandoned exhibit hall.

Through The VOID, travel back to that same night over a hundred and twenty years ago and the decaying Chicago World’s Fair. In groups of four, you will have your choice of six personas (avatars) through which you will discover frights, trials, and adventure around every corner. You will explore, touch and interact with the decaying ruins of the once-hopeful fair. Your goal is simple: explore the abandoned exhibits and don’t get caught by the demon Nicodemus.

Here is a preview of the attraction, but don’t say we didn’t warn you …
