Pre-ordering "X-Men: Destiny" on Amazon got you early access to downloadable content: Emma Frost inspired suits. But it turns out the suits were already a part of the game, so there is no downloadable content. Amazon sent this message to customers who pre-ordered the game:
Dear Amazon.com Customer,
The Amazon Video Games team thanks you for ordering X-Men: Destiny. It has come to our attention that original directions sent out were incorrect. Please see the correct instructions below on how to receive your Emma Frost Suits.
