The popularest hack is "Gorden".
There are some VIP Hacks but its not easy to get it.
Try to play without.
A easier trick is, try to get some NX and buy Elite moderator and then go to the platin server and play fireteam.
Cabin Fever up to 200-1000 Exp per game 30-60 mintues
Black Lung 100-600 exp 30-40 minutes
Desert Thunder 100 - 250 exp 3-7 mintes.
Thats the fastes level and its clean.
No bans :)
Its much bether than hacks and no one dislike you
i hope i could help you
best regards daarmy
