Don't purchase this game for $33.33 in the Steam Holiday Sale, when you can get it for $20.09 from Amazon. It is possible that this game could be discounted further in the Steam Holiday Sale, though I would be surprised, considering that it is a relatively new release.
Please note, you will need to do the following in order to download this game.
- Use a service like Unblock-us so that your computer appears to be in the United States (7 day free trial available)
Give your Amazon account a U.S. address, I used the address for the Australian embassy: 1601 Massachusetts Ave NW Washington, DC 20036 United States
I purchased the game using my CBA debit MasterCard.
- Download the Amazon executable, which will contain the Steam product key and installation instructions.
I was emailed the below offers after purchase:
