On the same theme, Jawz is the other way round. You must use your underwater gun sights to shoot up marauding sharks, whilst avoiding the gunge dropping from poisonous jelly fish on the surface. The game was originally made by Elfin - it's being marketed by DK Tronics probably hasn't made all that much difference because unfortunately it has a very limited appeal for serious arcade addicts. Good for younger children.
