A shooter often ranked among the best on the Genesis, and a pricey cart.

Technosoft developed and published this horizontal shooter, which reached Japan on 8 June 1990 and North America in October 1990. Mean Machines Sega praised its parallax-scrolling backdrops and sprites, and said the sound and gameplay were great as well.

Mega placed it 17th in its 1992 list of the top Mega Drive games, and Electronic Gaming Monthly called it the best shooter on the Genesis.

“Thunder Force III is one of the most professional, arcade -I ike console games I've ever seen. … The best shoot-em- up on the Mega Drive.”

— The Games Machine, August 1990

“People out lor the best blast on the Megadrive should go for one or the other of the games I mentioned earlier, but if you can't get your hands on either, Thunderforce III is a worthwhile substitute, packing a powerful punch in the shoot ’em up stakes.”

— Mean Machines, October 1991

“The Rynex fighter is back in a six-level graphical tour-de-force. The graphics are truly marvellous, with parallax-scrolling backdrops and some great sprites. The sound isn't bad, either. Put those together with the great gameplay and you've got a superb shoot 'em up which is highly recommended.”

— Mean Machines Sega, December 1992

“© Brilliant graphics, sound and gameplay. A very addictive blast. Recently superseded by Thunderforce IV.”

— MegaTech, May 1993

How the Sega Genesis version differs

The Genesis game was the original: its success led to the arcade version Thunder Force AC.

In 1997 Electronic Gaming Monthly listed the Genesis game as the 59th best console game of all time and the best shooter on the Genesis.

  • Arcade. Thunder Force AC, on Sega System C-2 hardware, is almost graphically identical to the Mega Drive game, borrowing enemies and stages from Thunder Force II and adding some original content.
  • Super NES. The Super NES port, Thunder Spirits, does away with level selection, changes several levels, and has a modified soundtrack.
  • Sega Saturn. Thunder Force III was re-released in 1996 in Thunder Force Gold Pack 1 for the Sega Saturn.

Before you buy

Among US carts this is one of the dearer ones, well above the median. The Japanese Mega Drive cart usually costs less than the US one, loose and complete, and has a different cartridge shape. A complete US copy means the case, cartridge and manual.
