Lochjaw

Lochjaw is a rare Atari 2600 game based on a deep-sea diver hunting for treasure.

This game plays very similar to Pac-Man, without being nearly as smooth in the control department. Move around a maze collecting dots. Avoid the shark that swims across the screen randomly. When you collect all the dots, simply bring them back to the center of the screen and more will appear.

You are a deep sea diver in search of a fabulous treasure of diamonds that spilled from the hold of a Spanish galleon that sank during a fierce storm in the early sixteenth century. You dive deep into the murky darkness of Dave Jones' Locker, and enter the shark-infested maze of kelp to retrieve the treasure. You know your mission is rife with danger...the menace of the man-eating sharks that patrol the kelp beds...the lurking menace of the legendary Loch Ness monster, a beast that will pursue you relentlessly if you dare invade its territory.

Apollo was sued over this titles similarity to Jaws. So they re-released it as Shark Attack with a few minor changes. Making the Lochjaw titled version very valuable, try at least $250. Games with boxes and manuals are worth even more.
