Until then, maybe look into other Exotic weapons in Rise of Iron, such as the Thorn Quest, Gjallarhorn Quest or Khvostov Quest - especially if you want to complete Rise of Iron's Record Book. Needless to say, the Outbreak Prime Quest is quite the task, so make sure you have a committed team to help out. Within hours, Datto and the Destiny sub-Reddit revealed the full steps to get the rifle, from monitor locations to starting the Channelling the Corruption quest and the various SIVA Engine puzzles. Streamer Datto and his team were among the first to get the 390 Light Pulse Rifle (!), with other players following suit.
After a week of the community working one of Rise of Iron's biggest mysteries - how to activate all of Wrath of the Machine's monitors - the puzzle has finally been cracked, paving the way to starting Destiny: Rise of Iron's Outbreak Prime Exotic weapon Quest.
