Call of duty modern warfare and black ops 6 title should at least have mod support for offline modes such as Campaign and Zombies in Solo. This will make getting veteran campaign and zombies achievements easy.
Hello!
Both Modern Warfare and Black Ops 6 require a constant connection to the game servers. Even their single-player campaigns. Aside from this, their anti-cheat also poses a problem for trainers. Therefore, a trainer is not possible.
There is no “offline” mode in these games. Single-player doesn’t necessarily mean offline. No trainer developer anywhere on the internet has a trainer for these games for these reasons, unfortunately.
