lol I mean the patch
This patch is still marked beta so wont be in Steam any time soon. I'm not even sure if it will ever be based on what I read here. I just make a copy of the HOI3 folder (from under my Steam folder), patch it to SF 2.04f, then apply the DI:G patch. To run the game, just launch hoi3.exe from the folder you copied over. You don't have to launch this one through Steam.
