Reaper weapon........ Available in the future to buy or win or something?

I've been through the missions (main, side & challenges) where you use it. I was at a minor ark fall the other night where there was a glitch, no crystal but EGO chick kept hollering it was there. A side mission popped up right in the middle of it. The one where you get the weapons box key and open it and low and behold there is a Reaper. I was able to keep it after all was over and run... all be it slowly.... to a nearby major hellbug ark fall AND WORE THEIR A#SES OUT! It was awesome. Then shortly after that was over it disappeared:(

Wouldn't count on it. It's a super weapon. Its use is supposed to be limited.

I had a similar experience a few nights ago though. Matron spawned within view right after I completed that same emergency. Needless to say, I topped the chart.

Has the same base dmg as an AR, seemingly... Larger mag, obvs, but a very specifically modded LMG would likely be a better overall weapon, imo. That said, the reaper is jekton of fun.
