Enter if you dare

Long before Dock World became known for the Mecalodon, crowds gathered here for a very different reason: its aquarium.

Once celebrated as a wonder of the deep, the Aquarium of Dock World was home to rare and fascinating creatures, some so bizarre they seemed to defy science. But in the 1990s, the site suddenly closed without explanation. Whispers tell of accidents… forbidden experiments… and unnatural disappearances. Today, salt, damp and time have corroded the walls. Water still seeps through the cracks, and broken glass glows with eerie lights from within.

Drawn by the booming success of Dock World thanks to the Mecalodon, the owner has decided to reopen the aquarium. Not out of passion for the sea, but out of greed. Not a penny has been invested. The infrastructure remains rotting, the crumbling tanks unsecured. And yet… something still moves behind the fragile glass, as if the aquarium’s former inhabitants never left.

The official reopening is set for 11 October. From that day, you will be able to step inside once more and uncover the secrets that lurk in the depths. But beware… in this place, it might be you who ends up under observation.
