Epic Games has pulled the Infinity Blade games from Apple’s App Store, saying it will no longer sell the trilogy or in-app downloadable content for the iOS games. In a statement announcing the removal of the Infinity Blade trilogy, Epic said that other projects, including the J.J. Abrams/Bad Robot game Spyjinx, would be its main focus.

“At Epic we strive to put players first and to provide a supported, full-fledged experience in every game we publish,” Epic Games said. “With the development of Spyjinx and other projects, it has become increasingly difficult for our team to support the Infinity Blade series at a level that meets our standards.”
