I know, this is old news. And HL2DM / Lost Coast came with HL2 for everyone who bought the game. But there's a new group of people who can make use of it: those who were gifted HL2 from a friend that purchased the Orange Box!
Anyway, here's the link.

It's nice because like all Steam games, you don't have to actually install it on the computer with the Radeon. I used my work laptop to unlock the games, and then could play them on a better PC.
Still looking for an HL2: Episode 1 gift now... : )
