Haven't played Titanfall yet? It's probably time you did, because you can currently grab Titanfall on PC for only £3.88/$5.99.
As an Amazon US listing, you'll need to ensure that you've registered a US address (any US address) if you're a British or European customer.
As far as I'm concerned, Titanfall is hands-down the best multiplayer shooter of 2014, and I don't make that statement lightly. Though skinny in terms of content at launch (which has since been bulked out considerably in numerous free updates), its empowering vertical parkour, massive mechs and superb maps provide a massive skill ceiling yet make the game accessible to anyone, while causing the industry to react by shoving freeform mechanics into their own titles. It's an immensely important game and one that's an absolute steal at this price. See also: COMMENT | Be Advised: it's time you gave Titanfall another chance
Thanks to MrCollective @ HUKD, who found this before I did, as well as Gooner and Neotrix for the tip!
