Unfortunately, you will have to get someone with a US Steam acct to buy it and gift it to you. If you can buy the disc, then do that. You *might* be able to use the disc code to activate it on Steam. I tried using a VPN to buy a region-locked game once, and the sale did go through, but it never showed up in my games list. Steam eventually had to refund my 'Steam Wallet'. Just a heads-up if you're contemplating that. SwiftKey 3 | Samsung Galaxy Note 2 | Tapatalk 2 | Omega v15
Let us know if berserk's trick work.If not, don't worry, a few GATT members are based in the US of A.If you want it, we could arrange with one of them.
Buy it from Amazon, and use the code to activate it on Steam.
