What happens is once you register the game with Steam(which is automatic when you buy it using steam), they give that to you as well. But just like when you buy a game over steam, you still have to wai for it to DL before you ca play it. That's what they mean about going to tools to download it. It only works if you have a source game(Counterstrike, Half Life 2). For whatever reason, the promotional copy of HL2

M did not come with that.
