It seems the 'Greentext' memes are becoming real as an "epic, new quest" explained as a "never-before-seen, multistage mission in The Taken King that will test the speed and strategic abilities of Destiny players in new ways" will require a Redbull can purchase and specialty code in order for gamers to participate. People certainly aren't happy about this new 'experience', as seen on Games Radar.
Once entered, the code will unlock this quest for all alongside bonus experience points soaring at a rate of 50% for only 30 minutes. How do you unlock more experience bonus? Buy more Red Bull cans! The experience bonus will be made available on the 1st of July, with the quest launching on September the 15th.
Released alongside The Taken King expansion which will cost us all $40, the quest will be exclusive to Red Bull drinkers only until January 1st, 2016. It also seems this is a US-only promotion at this stage.
