The rulers of planet Neptune have devised a devious plan to destroy Earth by melting its polar ice-caps and imprisoning humans in underwater factories to harvest their flesh as a food source. The Neptunian monsters then target the cities, flooding them with seawater. However, one hope remains: Narikeen, a notorious pirate who has been wreaking havoc worldwide.
You play as Narikeen on his submarine, Sqoon , equipped with two deadly weapons: an upgradable missile launcher and ice-bomb. Your mission is to destroy the factories and free the humans trapped inside. As you progress through eight levels set in sunken countries, you must rescue nine people at a time before they are crushed by rising seawater, while managing your limited fuel supply of 60 seconds.
