The Silver Credit is a type of Bonus Credit introduced in the New Play Control! series and Metroid Prime Trilogy; they are obtained in Metroid Prime and Metroid Prime 2: Dark Echoes by obtaining each a Chozo Artifact, Dark Temple Key, or Sky Temple Key, defeating some bosses, obtaining 50 or 100% Logbook entries in Prime, or 100% items in Prime. An additional Silver Credit is awarded for escaping the Frigate Orpheon. They are used mostly to buy from the Soundtrack Gallery, though two are required for the Fusion Suit.
