Well according to this the Uncharted 2 beta offer isn't just exclusive to Best Buy. And like I said if it was Sony would have a lot of pissed off PS3 owners on their hands.
Its not excluisve to any retailer. You buy the game and you can get into the Uncharted 2 beta. The Uncharted beta voucher is packaged with inFAMOUS.
Will all the inFAMOUS games have the vouchers or only the ones reserved in a specific store?
Also, are europeans gonna be able to play the beta?
You’ll be able to get a multiplayer beta voucher inside inFamous no matter where you purchase it.
And, yes, we’re working on getting the beta set up in Europe too (we’ll let you know as soon as we do).
