I preordered this game through Amazon as I prefer to have physical disc copies of games as opposed to digital download only. However it seems I have not received any preorder content code. Amazon say I have to contact Frontier. Was the preorder content only for those who ordered direct from Frontier or should it be being provided by all retailers who took preorders? If the later can someone within Frontier please fire a shot across the bows of Amazon to get their act together. This was for Xbox system.
