[Enuo]

I'm wanting to mess campaign so i wanted to know if would be actually possible to cheat a custom campaign

Yes, it is.
A campaign file (w3n) has a lot of maps inside id (every map is a campaign level)
U need to extract every map inside the w3n and extract every war3map.j, cheating all the maps inside,
and if the w3n file have a war3map.j, cheat it too.
