Why play SOMA when you can make SOMACH?

This never works for me, is there something else I'm missing? I created a folder to store my mods in simply called mods since I didn't have a folder like that. But it still just doesn't work, with the solution you gave.

When you try running the ModLauncher through Steam (click on SOMA > Launch Mod) do your mods appear there? If not, I suspect you do not have an entry.hpc file in your mod's root directory (SOMA/mods/<mod_name>/entry.hpc).

If you don't have one, that would be my first guess as to what is wrong. Copy and paste one from another Campaign, since AddOn's are slightly different.

You may also need a main_init.cfg, but I'm not sure if that is required to see the mod.
