Early Retail Version of Half-Life 2 - CS: Source included in HL2 Steam key?
I have a retail copy of Half-Life 2, likely purchased sometime in 2006. The DVD box claims that the game comes with a copy of Counter-Strike: Source, but I see only one Steam key on the inside of the box. The question I pose to those of you who remember buying the retail copy of Half-Life 2 is, does this key activate both Half-Life 2 and CS: Source?
I need to know this as I wish to trade the Steam key with a friend of mine, and he is primarily interested in CS: Source.
TL;DR Is my retail DVD copy of Half-Life 2 missing a key for CS: Source, or does the one key activate both games in the recipient's account?
