hey guys! i am currently downloading bo3 and it's a cracked version, but i am only downloading it for the offline zombies(going to play only zombies). i tried searching if it's possible and people are telling that you need to use cheat engine and stuff to make it work! and there are others who say you dont need to use cheatengine cause you can play offline without it(i think because of some update maybe) i really confused and searching for help on this, do i need to do the cheat engine thing? or when i open the game i can directly play zombies offline,plz help,tnx.
