Hello there!
This giveaway is a joint promotion between
The Proxyname trades and sales Emporium - the biggest tradelist on SteamGifts! - and
http://www.RandomAccessMedia.co.uk- if you're looking for great - but lesser known - cult films, monster movies, sci-fi, horror, good music and comedy it's a good place to go.

We also have exclusive giveaways each week for members of our Steam Group. Join the group and get access to member-only game draws. You have a better chance of winning (far less competition) and we hope you'll occasionally look at our tradelist (2 newsletters a week and we won't spam you). Everyone wins.
(Usually there are 3 exclusives; last week - The Silent Age - Q.U.B.E: Director's Cut and Men of War: Assault Squad - Game of the Year Edition).
Either way, good luck!
