Back in May/June Alienware was giving away free codes for CoH2, which I got. The code is only multiplayer/skirmish, so single player says "purchase" when I try to play. I currently have WFA too but I don't think that would really effects this at all. I found a guide somewhere earlier that said the "Digital collectors edition upgrade" upgrades your gave to have single player but its not on the steam store anymore.
By the way I am talking about the Russian campaign that comes with the base game, not AA.
Ah, I know what you're talking about and which promotion was that.
Its multiplayer/skirmish exclusively access and if you want to try single player campaign, you need to buy base CoH2(avoid steam unless its 75% deal, otherwise you'll have it cheaper at your local game stores).
What MajorBloodnok is talking about are Theater of War packs, which also need to be bought separately, except the first one that comes with the base game, which will unlock soviet campaign for you.
