Sea Devil © 1972 Sega Enterprises, Limited.
Electro-mechanical hunting game. A manta ray moves around the playing field and the player shoots it with a spear gun. It has a series of slides on a wheel that makes the manta ray move and thrash around when shot. The game features electronic sound and an 8-track player. It is essentially the same game as Sega's "Killer Shark
", but Killer Shark has a shark instead of a manta ray.
