So it looks like the red bull promotion unlocks a bonus quest early. In case anyone is interested. BONUS XP ONE-TIME CONSUMABLE Focused Light is a one-time consumable Bonus XP buff which increases all experience gain by 50% for a period of 30 minutes. Each specially marked can includes a code. Multiple codes can be redeemed but one code can be used at a time. Once Redeemed, Focused Light appears as an in-game message at the Postmaster vendor. Please ensure you have free Postmaster slots before redeeming multiple codes to avoid losing Postmaster items. EPIC NEW QUEST DESTINY: THE TAKEN KING This epic, new quest is a never-before-seen, multi-stage mission in The Taken King that will test the speed and strategic abilities of Destiny players in new ways. Quest only needs to be unlocked once per account. This content requires purchase of The Taken King on the Destiny account on which it is redeemed. It looks like the quest unlocks the day taken King is released. If you don't get the red bull code it will unlock in January I believe.
