If you would like to request a refund for one of one of our titles
purchased through Steam you can find the request form and policies here:http://store.steampowered.com/steam_refunds/
For those of you who also have the EU right of withdrawal applicable you can find more information here:https://support.steampowered.com/kb_article.php?ref=8620-QYAL-4516
you purchased the game via a third party website that was not
Steam/Valve you will need to contact them for their refund policy and we
can provide no direct support on those key purchases. We do not
recommend buying keys outside of the Steam website for this reason.
