So, you know that ATI/Nvida card offer? I have an Intel card. I used a program called 3D brown townyzer which emulates graphics cards. I have an Intel card, so I couldn't get the deal. So, I set 3DA to say that I had an ATI card, and lauched Steam with that setting. I redeemed the offer and got HL2DM and Lost Coast for free! :D
muahaha
