The Ocean Hunter (オーシャンハンター) (also known as The Ocean Hunter: The Seven Seas Adventure) is a 1998 shooting gallery game developed and published by Sega. The Ocean Hunter runs on Sega Model 3 hardware. The cabinet features artistic renditions of the bosses of the game, some with faux Greek names: Οχτοπυσ (actual Greek would be Όκτώπους); Λεϖιατηαν (actual Greek would be Λευιαθάν) and Χψχλοπσ (actual Greek would be Κύκλωψ).

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.
