I had the impression there was a way you could link up with a friend over
the internet and play the singleplayer game cooperatively.
But I can't see how to do it. I notice there's a bit about "The Friends
network is currently unavailable." Is this the way, if it was working,
you'd link up to play a friend cooperatively?
How long has it been unavailable? Are there plans to fix it?
Or is there another way to do the singleplayer missions cooperatively?
Or was there never a way to do this? (I assume there is, since you seem to
have to go through STEAM even just to play the singleplayer game).

There is no cooperative play in HL2.
Oh yes at some point we managed to make a friends list :)
