First person shooters typically use the right trigger to fire; for various styles of attacks, beat ’em ups often use X, Y and B; Radiant Silvergun has different weapons mapped to A, B, X, Y, left and right bumper and right trigger. In short, its heavy on the guns. Radiant Silvergun, developed by Treasure, will be joining Guardian Heroes (also developed by Treasure) in the Saturn-to-XBLA port ship. Much like Guardian Heroes, Radiant Silvergun also has some older mechanics that work surprisingly well despite being difficult to acclimate to.
