For ESP. Recorded Prefiring with shotgun multiple times on floodzone. This is 3 seconds after a fresh spawn, therefore knowing I was not spotted. 

I was abusing TUGS that entire round.  I usually hide them on rooftops or under the stairwell.  There's also the very loud and obvious "spawn noise" when you spawn on a nearby teammate, so that could have given you away as well.  I think I recall killing you as you spawned off a squadmate in the central waterway and headed for the stairwell while I was on the second floor catwalk.  If that's the death you feel was suspicious, I just heard the spawn noise and I believe you were running straight at the TUGS I had set up beneath those stairs.  Unfortunately I wasn't recording last night but I can assure you that it isn't ESP, I'm just trained to have my eyes on the minimap probably more than 50% of the time on Flood Zone.
