There’s Special Editions, and then there’s Battlefield 3 Steel Book Edition.
Gamers who pre-ordered the game through Swedish retailer MediaMrkt.se will receive the Steel Book Edition exclusive to Sweden. Said edition includes the Strike at Karkand expansion pack and all the other Limited Edition benefits. It’ll also come in a metal case.
Again, as of now the Steel Book Edition of Battlefield 3 is only available for Swedish gamers, but neither DICE nor EA has ruled out other countries, so don’t give up hope just yet.
