Destiny 2 is out now, and among the elements that you can play beyond campaign and the Crucible is the first of the game's weekly Nightfall Strikes. A Nightfall Strike is a special version of the activity, with special modifiers to crank up the challenge.
A post on Bungie's website confirms many of the details about this first Nightfall Strike, including the name, "The Arms Dealer." Your task is to "shut down the operations of an ironmonger providing weapons to the Red Legion."
