So how does it work? The tokens are doled out in four tiers: red, blue, green and gold. Red tokens are gained by scanning enemies and items, blue for scanning lore and completing side quests, green ones you receive from friends and gold is achieved by destroying bosses on various difficulties.
According to the tipster, tokens can be traded in for bonus content in-game, but are also used to track progress amongst your friends. Vouchers for those friends can be found and then sent in the form of green tokens as well. We've seen these tokens in recent videos of Metroid Prime 3, but we may have a wait ahead of us to find out exactly how they function.
