Unable to decipher Heinrich's notes themselves, they plead with Reno to complete his father's work, insisting it's what Heinrich would have wanted.
Reno reluctantly agrees to join the perilous mission. Aboard a state-of-the-art submarine, Reno and a diverse crew of scientists and military personnel descend into the icy abyss. What they find is a nightmarish labyrinth of ruins, haunted by a malevolent force that preys on their fears and sanity. As the crew succumbs to paranoia and hallucinations - hell breaks lose —Reno must use his intellect and survival instict to not succumb do something even worse than death.
As he delves deeper into the ruins, Reno uncovers a terrifying secret that his father tried to hide: the ancient city is not just a sacred site but a place cursed by sinister powers.

Trapped beneath the ice, Reno must confront both the ancient horrors and the treacherous organization, battling to escape the cursed city and seal its dark secrets forever.
