A new civilization is flourishing in the seas of an alternate Steampunk world, but giant ocean monsters are attacking shipping vessels, harbors, humans and native marine life with increasing frequency. Ordinary marine predators such as sharks have begun to follow in the sea monsters' wake to scavenge what they could from the destruction caused. Frightened for their lives, the people issue bounties on the monsters' heads. The underwater adventurers Torel (Player 1) and Chris (Player 2) head out to defeat the horrible creatures.
