The release date for the latest Batman video game, Arkham Knight, has been delayed until the beginning of 2015.
The adventure, which is the third in a series, was initially scheduled to go on sale for PlayStation 4, Xbox One and Windows PC platforms later this year.
The postponement follows a spate of delays to other high-profile games, including Dying Light, Mad Max, Quantum Break and The Order: 1886.
They are all "next gen" games, which use the most complex visual effects.
Mark Ward, a spokesman for Warner Bros Games - which owns the London-based developers of Batman, Rocksteady - said the decision to "extend the development of the game" was taken "to ensure that the trilogy gets the epic conclusion that Batman fans want and deserve".
Mr Ward added that Batman: Arkham Knight is the "most ambitious title Rocksteady has ever created".
