Radiant Silvergun originally released exclusively in Japanese arcades. Only a few months later, a Sega Saturn port was released, which was also exclusive to Japan.

The Sega Saturn version later became one of the most expensive video games on eBay. However, gamers who wanted to experience it at a lower cost eventually received an Xbox 360 version, and more recently, ports for the Nintendo Switch and Microsoft Windows.

Radiant Silvergun was developed by only ten people.

It became famous for not including power-ups, as the main designer believed they were too distracting and often caused players to lose more lives while trying to upgrade.

Unlike most shoot-’em-ups, Radiant Silvergun features a unique system that rewards color chains.

Masato Maegawa, the game’s director, personally visited Japanese arcades to observe how fans enjoyed the game.

Boss battles can actually be won by simply surviving the fight—you don’t necessarily have to shoot.

Radiant Silvergun is notoriously difficult; only 2.8% of Xbox Live Arcade players managed to complete it.

The arcade version was remarkably small, using only 12 MB of ROM data.

Radiant Silvergun is widely regarded as one of the greatest shoot-’em-up games of all time and helped revive the genre in the late 1990s.
