I have 8 copies of Deus Ex: Human Revolution for Steam available.
These are Russian retail keys, but the game is playable in English (+French, German, Italian, Polish, Russian, Spanish).
They do need to be activated via VPN for anyone outside of Russia, which I will take care of.
Once activated, the game it can be played, region-free.

2.5 BTC plus the login and a temporary password of the Steam account that you wish it to be activated on.

Please PM me or respond in thread with any questions.
