Radiant Silvergun is a shoot 'em up developed by Treasure. It was originally released in Japanese arcades in 1998 and subsequently ported to the Sega Saturn later that year. The story follows a team of fighter pilots in the far future who are battling waves of enemies summoned by a mysterious crystal dug up from the Earth. The player hosts an arsenal of six different types of shots to choose from, and a sword to destroy nearby targets. The stages are tightly designed to present players with scenarios that can be approached differently with the various weapon types.
