XCOM: Enemy Unknown is a pretty impressive real-time strategy game that we're big fans of, and despite only being available on Steam for a few weeks it's now half price until July 22. Considering this is a $39.99 value game that can now be yours for just $19.99, it's well worth pulling the trigger.
The iOS version of the highly rated XCOM: Enemy Unknown is set to hit the App Store this week on June 20. The turn-based, tactical RPG, alien-blasting extravaganza won't be coming cheap though; it's set to cost a whopping $19.99/£13.99. But, there won't be any in-app purchases, and it'll be an almost identical port of the console and Mac version of the game.
