I've only used this for legit play, so this review won't be based off of rage. Aimbot: 5/5 Silent Aim works perfectly (especially with nospread), very customizable. ESP: 5/5 Doesn't drop my FPS, never lags and is not delayed. Misc: 4/5 No Spread does not shake like with some other hacks (for other COD games). Unlock Black Market Weapons works good, but classes do not save after closing game. Configs: 5/5 Works as expected. Overall: 5/5 I don't use Triggerbot or Radar, which is why I didn't put a rating for them.
Classes don't save because thats how the exploit works. It doesn't allow saving of classes.(I could be completely wrong)
The classes are saved if you inject the cheat in the main menu before going into multiplayer. I don't think there is some method to make it permanent in the game.
