the leaderboards were so easy to hack before patch 1.12
. all you had to do was edit and script a patch or simply download one that was made for you, stick it on a usb, unplug it from your pc then into your ps3, download it on, go into a match, kill yourself or kill somebody then BAM! leaderboards hacked.... or you can just ask hackers and sooner or later one will say yea ill hack you
