Bonus Credit

A Credit is an item introduced to buy extras on Metroid Prime 3: Corruption. They are obtained through a variety of methods, such as scanning objects or defeating enemies in a certain manner. There are four types of credits in that game:


 * Red Credit


 * Blue Credit


 * Gold Credit


 * Friend Credit

Friend Credits are obtained by receiving a Friend Voucher from players on one's Friend Roster.

Credits can be used to purchase concept art galleries, a sound test, and 3D dioramas, as well as miscellaneous features like a Screen-Shot Tool.

Metroid Prime Trilogy
Credits are also used in the Metroid Prime Trilogy versions of Metroid Prime and Metroid Prime 2: Echoes, as well as Metroid Prime 3: Corruption. The new types are:


 * Orange Credits for passing important points (mainly bosses) in Prime 1
 * Purple Credits, which have basically the same criteria as Orange Credits, except only while in Echoes.
 * Silver Credits are gotten by obtaining Chozo Artifacts in Prime 1 (plus one in/around the Orpheon section), and the Temple Keys in Prime 2.

There's a total of 48 playable songs (The unlockable ones being unlocked by listening to them while in-game.) There are 16 from Prime 1, 17 from Echoes, and 15 from Corruption. The songs from Prime 1 &amp; 2 are 1 silver credit each. The songs from Corruption, however, cost the same as they did in the previous version. The tracklist thus far includes:
