No more Killstreaks hack ?

Hi,


i want to play again MW3, but now my actually killstreaks are not working (when i die, my killstreak is reset).


I don't find any killstreak hack (support killstreak), does it has been patched ?


Thank you, and sorry for my langague.

Yes thats right, since 3-4 months the killstreaks are no longer patchable.
