To anyone who has the original HL games...
Activate the codes on Steam and see what you get, I read today about the platinum pack (I think) so i activated Gunman Chronicles and I got:
Counter Strike
TF Classic
DOD
DeathMatch Classic
Opposing Force
Ricochet
HL
Blue Shift
Yes I own them all already but Steam didn't know that so get Gunman and you get the lot! It's about £3 on eBay
