http://uppit.com/iy0e4mhcjr1r/black_ops_english_DLC.rar (remove the empty space) and just copy it into your Black Ops folder which is usually located in Drive:\Program (Files)\Steam\SteamApps\common\call of duty black ops.
Right now nobody can play them unless you bought it. Right now I am waiting for someone who does not own the DLC to finalize the crack.
Will post it ASAP.
(And then you can only play it on private servers who also run the crack; running that on dedi's will get you kicked and 2 weeks later VAC banned, VAC is not a problem on private matches because it does not run.)
