Capcom is putting out an iOS version of Street Fighter X Tekken, so iPhone owners can finally spend your bus/plane ride beating people up and not get arrested. The game is expected this summer.
The iOS Street Fighter X Tekken is based on the console releases, but features an IOS-specific controls and UI, as well as new modes and what Capcom has referred to as a "new take" on tag teaming. As you can see from the screen above, the game overlays controls on your iPad. How this will work in practice isn't known, but I can't wait to find out!
SFxT is compatible with iOS 5 or higher, and is playable on iPhone 4 and 4S, iPod Touch 4th generation or later, iPad 2, and the New iPad.
