(adsbygoogle = window.adsbygoogle || []).push({}); hello guys !! just i saw the thread of this and just have vedio with no tutorial ..
so this is easy steps and very simple:

1- First thing u need two ' Trophy system ' on ur CLAS ( Control 1 + 2 ) both
2-chose ur killstreak ( Lodestar + Swarm ) to earn a lot of xp
3- ur friend most chose two ' Blackhat ' on CLAS
4-start the game , use the 2nd control and put the Trophy system
5-now tell ur friend to hack the Trophy system but u need to use 1st Control to shoot the Trophy on the same Time when ur friend start hacking !! .. so u need to connect with ur friend skype or anything to do easy and fast ..

now should it works when u try to show ur Trophy system or frag will shatter automatically !!
and ur friend will got the xp , and when just u use ur killstreak Lodestar and trying to shoot
ur friend will got Unlimited xp

i hope that steps help u guys
