About Dark Sea

Dark Sea is a spooky adventure story game where you pilot an old rusty soviet research submarine known as P27 in search of the missing research team from the ODISEA Group.

Story

You play as Mr. Sidorov, a mechanic working for the secretive Soviet research group known as O.D.I.S.EA. You know little about the organization—only that your job is to maintain personal, one-man submarines used by the primary research team to explore deep fissures in the sea floor, known as Fractures.

After the detonation of the Tsar Bomba, a new Fracture—designated Fracture 17—opened in the nearby Kara Sea. Now, you've been called upon to pilot an old prototype submarine in search of the missing research team that vanished into Fracture 17 and lost all contact.

Gameplay

Dive deep beneath the Earths surface in search of your missing research team. Uncover the secrets of what they were searching for, and why they vanished. "Seek not, that which you do not wish to behold."
