Being played on two mounted turrets, the player and his friend take the role of two divers on the hunt for mythical sea monsters with huge bounties on their head. The player goes through various levels fighting sea creatures and collecting treasure and eventually going against the level's respective bosses. The bosses were all named after mythical creatures. Some examples are a megalodon, a kraken, and a pleiosaur.
