Why play SOMA when you can make SOMACH?

[Sovjet]

I think the wiki has been updated with better info about this, or it will happen shortly. But short:

Make a mods/ in the game folder (next to soma.exe etc). Put mods in here for the none steam mod launcher to find them. When using the steam modlauncher the mods end up in steam/steamapps/common/workshop/soma/... (or something very similar). You can copy a mod folder from the workshop directory to the mods directory to easier work with the mod and to use the none steam launcher to test it.

Type are as far as I know only StandAlone and AddOn. StandAlone makes a custom_story or total conversion. The AddOn makes an addon to SOMA, for example the loading bar mod in the workshop.

Images and extended descriptions can be created on Steam in the workshop.

PublishedID you do not have to bother about, the ModUploader will fill it out when you upload a mod to workshop.

I use the GOG version so i cant use the workshop for mods but i have a little test map made in the editor but i cant load them in to the mods folder. (with the mod launcher)
