I ran into this just randomly going into buildings. With all of the dead bodies looming around, I figured there had to be something good. I just didn't know that it was going to result in the Assaultron and Sentry Bot nuking me over and over.

I ran into this last night. What made it super obnoxious is that I was in Iron Banner with my “Top of the Mountain” Quest at 6 of 9. Because of this cheater, I ended up losing my match (just barely) and had to play an additional 2 matches to make up for it. It's almost as if Bungie never beta tests anything.
