I’ve read about this happening before but hadn’t seen it, until now. I was playing the op tonight with @lowlines when Sister Aria just exploded in a flash of light and died, I was bleeding out and lowlines had just respawned when it happened. @JoeKGBX I daresay this is unintended, nobody seems to know what causes it and in this video nobody was doing anything to her, she just died.
Here’s the first thread posted here discussing this - Did anyone ever one-hit Aria? (Glitch)
