THE GAMEPLAY
You’re trapped in a failing submarine with systems on the brink of collapse. Complete a series of critical repair tasks to restore power, life-support, and navigation and hope you survive long enough to realize you’re not alone in the darkness.
THE STORY
Morgan Spedden was just seven years old when he survived the Titanic’s sinking. Both of his parents were lost to the icy depths. Consumed by survivor’s guilt and a lifelong obsession to uncover the wreck, he poured decades into research and planning. In 1952, he abandons everything he holds dear to captain a one-man submarine into the abyss. What he discovers deep beneath the ocean may finally answer his questions… or destroy what’s left of his sanity.
