E3 2011: Infinity Blade sales push past $10 million

LOS ANGELES--Chair Entertainment took five months to develop its iOS game Infinity Blade and six months to make $10 million off it, publisher Epic Games announced today.

Epic Games today announced that its Salt Lake City-based studio's iOS game Infinity Blade has surpassed sales of $10 million during its first six months of availability in Apple's App store. It is currently available for the iPhone, iPod Touch, and iPad.

Infinity Blade runs on Epic Games' Unreal Engine 3, the under-the-hood technology behind big-name projects like Gears of War 3 and the Mass Effect series.

Since Infinity Blade debuted last December, the game has welcomed two free updates: the single-player themed Deathless Kings and Arena, an add-on that brought multiplayer and survival modes to the title.

As for the game, Infinity Blade features a medieval setting, with the focus placed on touch-screen-based sword-battle gameplay. In the title, players can explore a 3D castle, engaging in sword fights with various villains and bosses. Along the way, they will level up their characters, build their stats, and find new items in the lead-up to a showdown with Infinity Blade's primary protagonist, the God-King.
