Last week, Apple celebrated the App Store’s fifth birthday by giving away five apps and five games, which included Tiny Wings, Where’s My Water?, and Infinity Blade II.

While infinity Blade II has returned to its regular $6.99 price, Chari Entertainment, the game’s developers, have told All Things D that the app was downloaded over 5.7 million times as a result of the promotion.

The action-RPG sword-fighting game added 5.7 million new players in seven days. Laura Mustard, publicist for the game’s developer, Chair Entertainment, said 1.7 million downloads occurred on Monday, the first day of the promotion.

The report goes on to note that the available in-app purchases could boost revenues for the company, which is probably getting bombarded with higher support queues and server loads.
