I guess this should be simple, but I can't figure it out:
When playing mods for the original Half-Life, back in the good old days, it wasn't worse than putting the mod folder into C:SierraHalflife and activating it in custom games.
However, when using Steam I really can't figure it out. It seems that the mods need to be configured rightly to become listed in the Games list. Thus, putting the mod folder in the C:SteamSteamAppsuser@jalla.com.. etc. folder won't work.
Any tips? Or do have to run HL as I used to earlier?
