Half Life 2 chapter select

[JoyPadJedi]

Guys...is there any file or line of config that tells Steam you've completed HL2 (and the eps)? I'm wiping the system soon and want the chapters to remain unlocked. Backing up from Steam never preserves this - anyone know how?

Ah brilliant. I assume '15' refers to the number of chapters in the game, so this can be adapted for Episodes and Portal?

Again, thanks.

No when you complete it you just get a level select.
