Internet reports suggest that Metroid Prime 3: Corruption comes complete with a mini achievement system which throws out colored tokens depending upon the completion of tasks. One of the most intriguing tokens is the 'friends voucher' that you can send to fellow Wii gamers in order to gain green tokens for both groups. Red tokens are given for scanning enemies, blue tokens are given for completing side tasks and gold tokens are awarded for beating bosses. These tokens allow you to gain access to hidden content through the extras menu.

Here’s a part of the game that I had no idea even existed. If you accomplish small tasks in the game, you are awarded with bonus tokens. These tokens come in four colors: Red, Blue, Green, and Gold. Red tokens are given as you scan a certain number of enemies/items. Blue tokens are given for scanning lore and accomplishing side tasks. Green I believe are when friends give you vouchers, more on that later. Gold tokens are given for beating bosses on various difficulties. You use the tokens to unlock hidden content in the extras menu. The final type of token is the “friend voucher”. Basically these are given for accomplishing some type of cool accomplishment in the game.

For example, when I beat the boss, a gold token flashed at the top of my screen saying it was for killing Lord Beserker. At an earlier point, I saved a GF trooper from being killed by two enemies. I was given a blue token for that one.
