Am I Doing Something Wrong?

I cannot find any values that are useful, and those that I do find, have no effect or don't carry over to round end. Any interesting hacks for zombies?

dont use cheat engine, its risk . soon or later you can get ban .. not worth ...
lets wait someone crate zombies trainer. it was before, but all are outdated.
i wait for it too, its good for farming keys in zombies.
game is dead on pc, not many players like on ps4.

Anyone tried downgrading their game? Might be worth a shot to use some of this outdated stuff.
