Steam code and 6 Free Frisbee's. (y) Shame I missed it again
You won't need one, and you're probably better off without one because even if you do use the 6 DVDs to install the game it will probably be so out of date that you'll need to download 6 DVDs' worth of updates anyway, so might as well just download the whole thing from Steam pre-updated. Regular CoD fans seemed to hate it, but I'm not a regular CoD fan and I really enjoyed the campaign. I guess it's either different enough to appeal to a different fanbase and/or the people who buy CoD just for the multiplayer were disappointed by that.

6 dvds, that beats my physical copy of Max Payne 3 I found.
