Slitherine

I am completely new to the game, and I want to play the custom campaigns& scenarios
I downloaded OOB in steam and bought one DLC, I have downloaded Squadmod and want to play the Banzai Japanese campaign. I have pasted the campaign in the campaigns folder and each scenario in the scenarios folder but there was no custom content button when I tried to play the game.
Can somebody help with the problem?

You need to unzip a mod in the Mods folder.

Thanks I figured it out! I have seen many of the instructions but the problem was putting the mods from windows program files. Putting the mods files from C:\Users\USER\Documents\My Games\Order of Battle - WW2 was the key

Yep it threw me for a loop the first time too (mods, custom campaigns and scenarios).

Tons of content for this game and I am too a newbie.
