well its not that hard if you want to add mods to a menu base for mw3 you need to add the code under Thread.Sleep500(); example:
You must login or register to view this content.
But for GHOSTS i dont know where you add the code i cant seem to find it.
& to edit what the text says on the menu or add more writing you edit this:
You must login or register to view this content.
For example i want to add godmode to the 5th option of the menu when it opens there are only 4 options i add "Super Jump On\nSuper Jump Off\ngodmode On\ngodmode Off". You would also need to add a sub menu & sub options for it so super jump would need another 2 sub options for it to be on there if its in another sub menu then add 1 of those to.
