Shadow-Shark! is based on the original Shark! Shark! game released by Mattel for the Intellivision system back in 1982. Shadow-Shark! incorporates new improved graphics, sounds, high scores and a few game play differences that make the game really interesting, but still with a "retro" feel. In Shadow-Shark! you are a fish that must avoid bigger fish, sharks, crabs and stingrays while eating smaller fish so that you can grow and rule the seas. Additionally you can attack sharks on their tails to grow faster and obtain bonuses. Shadow-Shark is a really fun and addictive little game, try it!.
