Best way to level up super fast issss?

A lot of people say play fireteam, cabin fever on extreme is the best way? Any comments or have a better/faster way?

Only if you're hacking its fast. Preferably, its Spy Hunt....5+ kills with a lot of deaths, then kill the super spy...and bam.

Yea do that method and you'll have over 300exp and gp

OPK a few super spies.

OMA 45 kills
Try to be the best

OPK like i am doing now.
I am SSG1 in few hours.
Dont spend GP and gift it to your main acc.

Got like 50.000 gp now on that acc
goes really fast

dont fucking hack, pepole that are sayign that are stupid! if you hack your banned then you have to restart and I dont think you wanna do that do you.
Fireteam extreme with 8 pepole Self Meds and FlameThrower

you will get about 1k+ exp a game

OR! if your pro and you spend NX you can go to blackmarket and play DT if you have a good team which most are really goood. you can clear it in about 2-4 minutes and get 100-200exp
