Custom story folder?

[TiManGames]

They didn't necessarily change it;

Non workshop modifications should go into a "mods" folder in SOMA's root.
Workshop downloads to that specific location, since Workshop content is stored separately from the game.

And how do I launch the non-workshop mods? with the ModLauncher.exe?

When I try to open this file I get an error:


Steam API failed to initialize. Workshop subscribed items will not be available.
