I use External BoxESP v5.2 and MW2 Liberation 1.4. I have been using that setup for months and i am not banned. I don't know why but VAC loves me. Hacked for 6 months and not banned. GG...
But only use it if you don't care about getting banned. I only play on the PC to hack. I play xbox for serious gaming.
Again, this IS DETECTED. I am just not banned. So maybe it isn't, idk.
