Same as all the others; EFIGS+PL key (English, French, Italian, German, Spanish +PL) not a region restriction as far as I know... It does require you to haw the steam client in one of these languages though (perhaps... Not sure if this is a requirement either but just FYI so don't enter if your client is not in one of thee languages to be on the safe side).

Oh, and Please be online when it ends (and for an hour or two after it ends as I intend to give away the key and make a second giveaway immediately after).
