Ha, i encountered a BF4 hacker yesterday, it was the second time i encounter one...
i was parachuting down as soon as i spawned, i knew where he was since he killed me before... the distance between me and him was very far...
Somehow tho, as soon as i went close to him with my c4 while parachuting, he instantly aim-locked at me with 100% accuracy, and killed me... even tho there was no indicator whatsoever that i was near him.
You may say that, OOOOOOOH BUT YOU PARACHUTED YOU DUMPFUCK HE MIGHT HAVE HEARD YOU, the thing is... i parachuted as soon as i spawned, if he really did hear me using my parachute he would have tried to look at me or try to find me as soon as he realized there was someone parachuting somewhere... but no... at the time he was behind a wall, and i wasn't in his line of sight for the whole parachute duration, which was about 8 seconds.
so yeah... that's that.
in tf2, it's all boring, stupid hackers... just like csgo...98% of hackers are just stupidly obvious.
