As incredible as it sounds, the full experience of 2k's and Firaxis' XCOM: Enemy Unknown has now hit mobile platforms. The game is available today through Apple's App Store for iPad and iPhone.
XCOM was released last year for consoles and PC. It received nearly universal acclaim, and ended up topping many best-of-2012 lists. Though the graphics and controls have been modified for mobile devices, the entire game is there for $20 - half as much as it costs on Steam. The game can be played on iPad 2, iPad 3, iPad 4, iPad mini, iPhone 4S, and iPhone 5 devices, as well as the latest version of the iPod touch.
