During QuakeCon 2010, ID Software's co-founder John Carmack demoed Rage on a iPhone 4 running at a very impressive 60 frames-per-second. And what's maybe even more impressive is the fact that Carmack believes this game will "kill anything done on the Xbox or PlayStation 2." We first heard of Rage coming to the iPhone and iPad back in March so it's good to see that this is finally going to happen and sooner rather than later.

Any first-person-shooter fan out there should definitely be chomping at the bit to see this one land into the App Store "later this year". And if one title is not enough, perhaps the planned sequel that will be available just in time for the 2011 launch of the PC version will make you happy.
