Re: Kiltron, do me and a lot of us a favour
Anyone who posts those files is likely to get their butt sued by Valve for releasing content.
By hosting the "missing" wad file for Steam users with his expansion Abalone is really doing this too...
Looks like you will have to either embrace Steam (I don't think you will get far with HL2 etc if you don't have it) or wait until they decide to release a patch.
Cheers for now
