While we knew it was coming after Red Bull accidentally confirmed Destiny's The Taken King, the energy drink company has hit go on its official site, revealing an exclusive Taken King quest. The "epic, new quest" is a "never-before-seen, multistage mission in The Taken King that will test the speed and strategic abilities of Destiny players in new ways."
The quest will be exclusive to Red Bull via an access code under the tab of promotional cans that can be entered on the site and requires The Taken King to be able to play. Drinkers will also get a one time consumable Bonus XP buff that will increase XP gain by 50% for 30 minutes and each marked can of caffeine will include a code. The XP boost will be available from the 1st of July, while the quest will be launching with the Taken King on September the 15th.

Mod edit:
While the quest will only be exclusive until January 1st 2016 there's no word on Red Bull promotions outside of the US.
