Today I played with a player that was using the masskill hack in Battlefield 3.
The strange thing was that I didn`t saw hackers of those type in a long time, since April last year to be correct.
Now I already reported the guy to a DICE developer and she was ingame with him and confirmed he was using masskill hack, he is already on a Banlist.
I wanted to report him here also so that you guys can do some research and Ban the new masskill hack.
