Bran new Call of Juarez game: Gunslinger is available for pre-order on Green Man Gaming. The games goes for $11.25 for Europeans (at least I see the price in dollars) when you use this voucher: GMG25-5GT67-87HJ9. Non-Europeans can always use this 20% off voucher instead: GMG20-GGN5D-FC3NA.
Call of Juarez: Bound in Blood comes with this for free but it’s not Steam redeemable! – info thanks to @tyrisflare
