Radiant Silvergun is a shoot 'em up video game developed and published 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.

Shoot 'em ups are a sub-genre of action games. There is no consensus as to which design elements compose a shoot 'em up; some restrict the definition to games featuring spacecraft and certain types of character movement, while others allow a broader definition including characters on foot and a variety of perspectives.
