I honestly don't care about hackers, and i'm not sure whether this was a hack or a bug/glitch, most likely the latter, but someone was in the dead position on my round this morning, killed me twice as well as load of other players on my team, because we recently took A & B inside the first part of the Subway which meant he was killing us as we spawned, and luckily i spawned elsewhere [i was going to make damn sure i was the one to kill him], and it took me to go round the back of him and kill him, but before that i observed him for a bit and realised that his character wasn't prone, but dead, yet still able to shoot at people.
Hackers hack because they can't play the game, they quite frankly suck, so it just takes a bit of thinking to try and put them down, but sometimes i understand it just isn't possible, and that's when you go and find another server to play on, rather than get frustrated.
