Infinity Blade 2 downloaded 57 million times during free promo
During the App Store's weeklong free-game promo, 5.7 million people downloaded Infinity Blade 2. Five point seven million people. Sit on that number for a moment.

In its first day alone, Infinity Blade 2 racked up 1.7 million downloads, and sales of its predecessor, Infinity Blade, rose 2.5 percent from the previous week, All Things D reports. Sales of Infinity Blade: Awakening, the series e-book, rose 70 percent. Neither supplemental app was on sale during the week, with Infinity Blade priced at $6, and Awakening at $3.

Infinity Blade 2 has now sold close to 50 million copies since launching on December 1, 2011, for $7. It was free as part of the App Store's fifth anniversary celebration last week, which also set free Superbrothers: Sword and Sworcery: EP, Where's My Water and Badland.

The next game in the Infinity Blade series, Infinity Blade: Dungeons, was canceled this year when developer Impossible Studios shut down.
