Thunder Jaws is an action adventure game, originally released for the arcades by Atari Games in 1990, and later ported to all major home computers like the 16bit Commodore Amiga, Atari ST and the 8bit Amstrad CPC, Commodore 64 and ZX Spectrum.
STORY / GAMEPLAY An evil woman named Madam Q has kidnapped a female group of swimmers (!) to conduct a series of hideous human experiments. You, as a secret service agen must stop her evil plans and rescue them as soon as possible. The game has two different gameplay zones (the underwater zone and the base zone) throughout each stage. Diving into the underwater zone you swim through the level looking for an exit to proceed to the base zone. You're armed with a standard spear gun to kill enemies like other armed divers, sharks or even destroy torpedo launchers. You may also find other weapons (of limited ammo that is) either on the ground or when specific enemies are eliminated. Inside the base zone, you walk and jump across platforms, shooting everything that moves until you reach the end of the stage. The enemies vary from divers, robots and more. Note that at the end of some levels you'll have to confront a big boss. Overall, Thunder Jaws is a neat game of great action.
GRAPHICS / SOUND The ZX version has nice graphics with nicely designed sprites and backgrounds, although the colors are limited compared to the C64 and mostly to the CPC version. The scrolling is slow but that does not render the game unplayable. As for this version's sound, Thunder Jaws on the ZX has a few typical shooting sound effects and explosions but no in-game music.
