Infinity Blade

Infinity Blade
Infinity Blade is a fighting game developed by Chair Entertainment and Epic Games and released through the App Store on December 9, 2010. It is the first iOS video game to run on the Unreal Engine. In the game, the unnamed player character fights a series of one-on-one battles in a derelict castle to face the immortal God King. When in battle, players swipe the screen to attack and parry, and tap the screen to dodge and block enemy attacks. Upon victory or defeat, the player restarts the game as the character's descendant with the same items and experience level. Developed by a team of twelve people, the game was intended to demonstrate the new iOS version of the Unreal Engine. Four free expansions added new equipment, endings, and game modes. The game made US$1.6 million in the first four days after its release, more than any other app in the history of iOS, and over $23 million by the end of 2011. Reviews heavily praised the graphics and compared the mobile game favorably to console games. Critics also praised the swipe-based combat system, but split opinions on the cyclical gameplay as either addictive or repetitive.
