This weekend the most sought after weapon in Destiny is being sold by Xur. For only the second time in the history of the franchise, you can pick up the exotic rocket launcher and its “wolfpack rounds”, which are homing missiles of doom. This is by far the most powerful weapon in the game, allowing soloing high level bosses and raids in PvE. You can pick it up for 17 Strange Coins, through 1 AM PST. Have your fun while it lasts, the Taken King expansion releasing September 15th is rumored to nerf the wolfpack rounds.
