I didn’t take enough math classes to properly convey the degree of the alarm that we’d need to set off to properly gauge this freebie alert, but, regardless, Infinity Blade ($5.99) just dropped to free due to Apple’s app of the week promotion. Infinity Blade is a platform-defining game, which utilizes the Unreal Engine and swipe gestures to bust out some of the best looking visuals out there coupled with a really slick swipe-based control method.

Sure, the original Infinity Blade might seem a little dated when held up next to its sequel, Infinity Blade II ($6.99) but both are phenomenal games that shouldn’t be missed. Seriously though, if you don’t already have Infinity Blade download it for free right now. You won’t be disappointed.
