Does this mod work with the Steam version of this game? I download and drop it in the /steamapps/common/Doom 3 folder but it doesn't have any effect it seems. I'm not sure what exactly I'm doing wrong. I've seen mention on the mod page and here of people using it on Steam but nobody says how.
A bit of guidance would be greatly appreciated :-)
PS: this is the vanilla, non-BFG version. I know mods don't work with the BFG edition.
