can you please check marteer456 (https://battlelog.battlefield.com/bf4/de/user/marteer456/)
I am sure this guy turned some hacks on... he killed me so often with headshots and also with shoots completely trough the wall...
He is also playing with wallhack because he prefired so often.
Feel free to collect sufficient evidence and report this guy by yourself since he is not yet reported.
Oh sorry i forgot the battlereport:
show all players then : marteer456
12 headshots 21% aim then look is "normal" stats on his profil...
A bit off from his former stats but still needs a bit of monitoring. Thanks for the report anyway.
