hacking in ca

I was wondering are there private hackers who keep there releases to them selves? I was just wondering ,because when i was playing ca and even after the patch theirs still tons of hackers. One was going through walls, trash cans, u name it. another just stood there knifing and killing all the zombies.
would like to know, and maba know how? thanks

They are probably vip hackers. Vip updates very fast after the patch. And most of the public hacks are patched. So, probably vip hackers.

ok but y pay so much for the game

They dun pay for the game. They pay for the hack
