Half life troubles

does anyone have the cd key for half life blue shift. Ive been looking every where for mine but it seems i lost it.

Then please contact the manufacturer of that game for advice. Make sure, you have your proof of purchase at hand.

I doubt you ever had one in the first place.

Valve distributes their games through the Steam network, you only need the CD key for the first installation then it is tied to your account. Even if you lose your CD key, you can reinstall the game by logging into Steam.
