This is Portabliss, a column about downloadable games that can be played on the go. XCOM: Enemy Unknown seems like it was built for iPad. The touch-screen controls on the iOS port are so good that the game feels like it was lovingly crafted specifically for touch devices from the get-go.

These controls are easily the highlight of the iOS version of XCOM (which also runs on the iPhone, by the way). With a redesigned HUD full of chunky buttons, completing actions in the game is a cinch. I actually prefer the touch scheme to wielding a controller. It's a simpler, more intuitive process, and the meat of the game is every bit as good as its console and PC counterparts.
