Sorry I didn’t get a picture of this because we wiped so fast. But I just had a game where we all died in the warlord fight at the end of a damnation chasm terminus mission. A big part of that was because an invisible sniper kept picking us off one by one and we had no counterplay. Several times I saw a laser coming from the elevator where we entered the room, but I couldn’t see or ping anything in that direction even with my veteran ult.
I think what must have happened is the sniper spawned or moved to the other side of the elevator and was shooting at us through the closed doors.
