Kosmocean, a planet covered by water, where humans survive on tiny islands, and factions lay spread across the sea - Viridis islands, that bordered on a pastoral lands, Utopia platform with its ancient steel Submarines, Cult of Noun and its Firetop Mountain.

Adventure and submarine exploration game. Control your Bathyscaphe with the help of a logbook. Through the game puzzles, bullet-hell sequences, and skill-based challenges, you will be plunged miles and miles into the depths where the ocean seems to have no end.

You are Ikki, a young boy living on a small island with his intrepid grandfather who taught him everything he knows. Together they built Bathys, a pocket submarine, using recyled material, flotsam and jetsam.

After a catastrophe, our heros are separated. All that is left is the incomplete logbook. Ikki's quest begins: he must find his grandfather.

You'll descend miles below the surface, where the sun never shines, where terrible currents, monstrous creatures and terrifying pressure are an insurmountable barrier to your progress. Where the ocean seems to have no bottom, a new world beneath the sea may hold the key to the survival of humanity…

You will discover a detailed water world brought to life with hand-drawn animated graphics and immersive sound design.
