Broken completely
At least the GoG version crashes on startup.
And another post about it says there isn't even an ETA for a fix.
Maybe if you bought the game through steam its not, but if you prefer the non-DRM route, don't bother.
This is where Steam/Valve is probably the ugliest - trying to monopolize the modding community
Sure you can publish your mods on steam... of course no one who purchased the game via other channels can access your mods...
I can understand how the lack of DRM is a great scaring point for the business end of games and they do provide a good distribution system and set of community tools and community as well but they make it really easy to lock out any one that purchased the game via any competitors.
There they really screw the games and the publisher as well mostly in the name of "more market share"
