Can you use streamcrack for zombie DLCs?

So in the dbd category here is a tool called steamcrack which gives, you the DLCs from dbd for free.
Does this work with call of duty games aswell? And how risky is cheating in this game? I would assume you can do basically anything since this game is pretty old.

Treyarch has the best anti-cheat of the CoD Devs, so I'd at least be more careful, generally you won't get caught on this game unless you get reported a lot so be weary of your blatantcy. And yes, you can use Steamcrack on all games, I wouldn't recommend using it at all, as most steamcracker downloads are littered with keyloggers and viruses, stay safe!
