The Red Bull exclusive quest and item in Destiny has finally been detailed. The Sunless Cell is a level 40 Strike, requiring players to defeat six enemies and a special Thrall. Once that is completed an 18 minute timer begins, and players must complete the Shield Brothers Strike before the time runs out.
The reward for completing this sequence is a consumable which upgrades the SR-0 Swiftriver Sparrow to the SR-1 Swiftriver, a “faster version of the sparrow received at the beginning of the game.” For those wishing to participate all you need is a can of Red Bull branded with Destiny and redeem the code at RedBullQuest.com. The quest will become active on September 15, 2015 when The Taken King launches.
