Dark Fathoms

Miles beneath the ocean's surface, a decaying redoubt barely protects Ryan and his companions from a watery death. Battling vicious assaults from cyborgs programmed by artificial intelligence to kill them, they're desperate to escape this underwater trap. But above the waves a new threat awaits: a massive predark super ship banished to the seas of Deathlands. Decades of madness have led to civil war between the citizens of the upper and lower decks. Now pawns in a bloody game, Ryan and the other survivors must destroy the ship or face their certain end at sea.
