Far Cry 3 and Assassin's Creed 3 have been mysteriously absent from the UK Steam store since release, despite being available in every other region (even the lesser liked ones, looking at you Zembla). This is no longer the case.
Details and links below.
As links go, this is the one to Far Cry 3 in the Steam store. This is the one to a picture of a cat looking shocked. And this is one to a Wikipedia page on velociraptors. And this is one to Assassin's Creed 3.
