The seven seas spread throughout the world. It is said that there is a monster for each of these seven seas. Ships are being attacked one after another. Sharks gather around monsters seeking human flesh. The ocean is not only a place of blessing but a place of terror. Defeat the violent gigantic monsters of the seven seas. An enormous bounty has been set for their heads. Brave youth go out to face the monsters.
The Ocean Hunter: The Seven Seas Adventure is a Light Gun Game released in arcades by Sega in 1998. Set in an Ocean Punk world where human civilization is being ravaged by terrifying sea monsters, you ply the seven seas with your trusty spear-gun seeking the bounties on these beasts' heads. While the oceans are swarming with all kinds of aquatic horrors, it is the Seven Great Monsters who are your greatest prize - and your deadliest challenge.Tragically, the game was never ported to a home console, and is now extremely rare. (Except in Singapore, where it's in practically every arcade. Go figure.)This game provides examples of:
Achilles' Heel: Apart from the soft-spots, each boss has a vital point that must be hit three times in order to win, including Kraken and Karkinos' eyes, Leviathan's throat and Charybdis' light.
Everything's Even Worse with Sharks: You fight no less than five giant sharks: White Death, the trio known as Kerberos, and the nightmare-inducing Leviathan. Normal-sized sharks are also common enemies in the first, second, and seventh levels.
Charybdis keeps deep sea eels in her mouth for boss fights.
Medusa and her jellyfish.
Gaia's Avenger: Rahab was pissed at humans for polluting, abusing, and otherwise messing with the ocean, so he created the other Great Monsters to put us in our place. Except Midgardsorm. Middy has been terrorizing the seas before Rahab made it cool.
You fight a miniboss, Basilosaurus, in the middle of a suspicious hole in the seafloor. Sure enough, when it seems you've won, the resident of that hole decides to stick its neck out and eat you and Basilosaurus. Cue the second half of the level.
Just Eat Him: Near the end of her battle, Charybdis decides to attempt this, simply inhaling you rather than spew gulper eels or charge to bite. Midgardsorm does this too, but with much more success.
Kraken and Leviathan: Pretty much to be expected in a game that focuses on destroying huge sea monsters. Kraken is a giant octopus and the first boss, while Leviathan is a Megalodon and the second boss.
Mini-Boss: Every level except Texcoco Great Lake has at least one. The final stage has four.
Mook Chivalry: The Mini Bosses "Hydra", which are three giant moray eels. They're not very bright as they attack the protagonists one at a time, instead of all three at once. Subverted by "Cerberus", three big nasty sharks who attack the protagonists all at one go.
Nintendo Hard: This game eats your quarters like Karkinos eats whales.
Prehistoric Monster: Ahuizotl, the boss from the fourth level (Elasmosaurus); The sixth level has Tylosaurus, Eurypteron, Dunkleosteus and Anomalocaris...as normal enemies! There's also a ton of trilobites and a Basilosaurus mini-boss.
Reptiles Are Abhorrent: Mook monsters include sea snakes and prehistoric mosasaurs. There's also the sub-bosses Sea Dragon and Black Dragon (giant marine iguanas)and Sea Serpent(a giant sea snake) and the boss Ahuizotl (elasmosaurus). (Despite its name, the sub-boss Basilosaurus is actually a prehistoric whale.)
Rule of Cool / Rule of Scary: Quite a few of the "monsters" are harmless to humans in real life if are left unprovoked. Namely the Sea Dragon and Black Dragon (marine iguanas), the stingrays, and Naga, Vitrya, and Kalya (the ribbon fish). Medusa (a lion's mane jellyfish) would only sting if touched and wouldn't actively charge at a person.
Sand Worm: Midgardsorm is a textbook example, albeit one that lives in the seafloor rather than the desert.
Sea Monster: Just about every popular sea monster gets a shoutout in this game. Sharks of assorted types, sea lizards, sea snakes, octopi, eels, giant squid, oarfish, angler fish, elasmosauruses, jellyfish, crabs, prehistoric whales, marine worms, and a mad sea god. And that's just the minibosses and bosses. Many mooks are also present.
Turns Red: All the boss fights will have two parts: part one, fight back the boss. Part two: the boss try his last trick on you, and you have to shoot his weak point thrice. The mechanics depends on the boss (eg: Kraken will wrap his tentacles around you, Charybdis will suck you inside her mouth and so on).
Again, except for the second half of the fourth boss battle. You get up onto some rocks and essentially play whack-a-mole, but with water instead of dirt, a harpoon gun instead of a hammer, and an irate dino instead of moles.
Underwater Ruins: Ubiquitous, but especially in Texcoco Great Lake and Panthalassa.
Warm-Up Boss: The first sub-boss is the easily-defeated White Death.
Timed Mission: However, White Death is attacking a scientist, and if you want to fight Sea Dragon, you'd better be really damn fast. If the scientist dies, you don't get bonus health and... well...
Womb Level: The second half of the West Ocean takes place inside Midgardsorm, a giant worm that's swallowed you (and countless ships) whole. You're swarmed by creepy parasites and kill it by attacking its heart.
