Many, many, MANY years ago (about 30 - 35) one of the first video games I ever played was a game about hunting sharks. The cab had a harpoon like gun attached, and if you hit the shark, a small trail of blood would appear.
I played that thing nearly every time I was in the Gold Mine arcade in Northlake Mall, Tucker GA. Does anybody else recall seeing it / remembers the name of it? I've tried to tell my wife about it but to little avail.
