Special thanks to YouTuber CyberChaos for the screenshots above. " Get me one, I don't care how you do it" about sums it up. With changes coming later this month to balance out the chances of getting high-end equipment, it seems a good bet Xur will eventually sell this amazing tracer rifle. Of course, whether you actually manage to get the Prometheus Lens or not is currently up to the fickle hand of fate, as it's totally random (although the odds obviously increase as you get more exotic engrams).
DESTINY 1 BEST TRACE RIFLE PATCH
You can expect a patch in the future to nerf the weapon as the angry hordes rise up against Bungie's lack of foresight on this exotic.

Reddit and various Destiny forums are absolutely ablaze on how unbalancing the weapon can be against other players with a ludicrously low kill time. While those abilities and high damage are great for the average mission, it also means the Prometheus Lens tracer rifle is absolutely dominating in Destiny 2 PvP right now, perhaps to an unfair degree. The rifle excels against large numbers of weak opponents, but because of its long range, it can pretty much devastate anything if you manage to hit it for more than a second or two.

What this means is if you are aiming well and have a target-rich environment, you will be firing a long time, and everything will be dead. The Prismatic Inferno ability kicks this thing into overdrive, upping the damage the longer the Prometheus beam is fired. That's already an awesome little perk, but it gets even better. Obviously the Prometheus Lens exotic rifle chews through ammo extremely quickly since it fires a steady beam, but here's the kicker - getting kills actually refills the ammo. One major difference from your average rifle is that the Prometheus Lens fires a continuous beam in whatever direction you are facing instead of launching individual bullets, giving it a jaw-dropping 1,000 rating. You might have noticed something rather odd in the stats on the Round Per Minute category.

This is a rotating quest with various rewards, so it shouldn’t be anything that you’re not used to. You need to head to Io and take on a mission called Interference. This quest step is slightly more involved. This will unlock the next step pretty much straight away. You need to pick the mission up from The Drifter, so head over and see him at the Tower. We’ll release a new, more conclusive guide, when we have all the facts. Everything we have here is based on datamined information.
DESTINY 1 BEST TRACE RIFLE HOW TO
Here’s everything we know about how to unlock it, though not that at the time of writing the quest isn’t currently available. However, we also know that there’s a new Exotic Trace Rifle on the way soon, Ruinous Effigy. Season of Arrivals brought with it a brand new, boss-melting, Exotic weapon, Witherhoard.
