I was at Gamestop the other day and saw they had MP3 Corruption. I took a good look at the case but couldn't find anything that said it had wifi. Does it have wifi or no? ???
No. There isn't multiplayer at all from what I saw.
You can send some type of "friend voucher", but I still haven't figured out what they do.
Friend Vouchers are little 'slips' that you find while playing the game. If you send them to friends, it gets transformed into a Friend Credit, which can be used to unlock extras in the game.
You cannot, however, play against your friends via Wifi.
Well, with it being a Wii game and being Metroid Prime I thought there would be some kind of multi player. Well, guess not. :P
