Im not sure if you can edit the campaign maps. Plus anuke (which is one person not a team) already made attack maps on the campaign, which are; Fungal Pass, Overgrowth, and Salt Flats I think.
hey theres a bug that does not allow me to enter a campaign map, the launch button is greyed out they it does if you dont have enough resources to enter the map, but i do though. I dont know if its because of the example mod i loaded in or just an actual bug.
when you download a new version of mndustry, your progress transferrs to that version also. Or you can switch to the itch app version which auto updates while still having ur progres
