BioMetal is a horizontal-scrolling shoot 'em up for the SNES developed by Athena, who produced the SNES shoot 'em up Strike Gunner S.T.G. the previous year. Athena published the game in Japan, and Activision published it in Europe and the US.
The player can assume one of six ship types in order to fight the eponymous hostile Biometals, an alien species bent on exterminating the human race. The design of the Biometals is strongly inspired by Alien and H.R. Giger. The biggest difference between the Japanese and European/American versions is the inclusion of instrumental music based on techno band 2 Unlimited's "Get Ready" album. The Japanese version has an entirely different soundtrack.
The game was followed up with BioMetal Gust, for the Sega Saturn.
Electronic Gaming Monthly's Mike Weigand gave Biometal a review score of 6 out of 10. He wrote, "...All the elements of an average shooter are here: huge bosses, tons of power-ups and weapons and great graphics. Unfortunately the perky techno-pop music by pop music group 2 Unlimited just doesn't belong...".
