There are a few newer or at least newer to my eyes mods out there for some of the weaps.. and playability.. that I think really look pretty cool for doom 3. I think this game really missed the mark because there are so many things that could have been done there with it to make it a lot more Multiplayer friendly. Anyways.. I just thought this was pretty cool..
