We were in a map last night were a few guys were just destroying us. He was mowing down 3-4 people (as assault) at a time. I am not 100% sure if punkbuster stops this, but I found a video that looked really similar to what was going on to us.

One of these guys had a kill to death of around 50/2 part way through the map,lol.
