This is how you get a mod to work to install it so to speak

[timberwolf15]

The only way I have gotten it to work is to do the following:

Get the Panzer Corps 2 Steam Key from Slitherine

Install Panzer Corps 2 via Steam (I think you only need to install the base game)

Once installed go to the workshop via steam via the PC2 workshop and subcribe to a mod (click the subscribe button)
for example the Grand Campaign 1 - user made campaign is a "mod" so go to the workshop and subcribe to this campaign\mod

restart the steam version of PC2

at the main menu click on MODS you will see New Game, Load Game, Multiplayer, Mods .. click on Mods

next click on Mod Manager you should now see a list of the mods \ campaigns you got from the steam workshop
next click on the box to darken the mod you want to be able to use then click on Apply then click on back

now click on New Game then click on Campaign you should see this mod \campaign in the list now along with other stuff you have click on which one ya want to play ...

(There is no need to explain this in a sticky in the Scenario Design section no need at all we can just figure it out for ourselves all we need to know is to install it to a campaigns folder - which frankly does not work for me the only thing that works is using steam)
