Ninja theory developer working on the upcoming playstation 3 exclusive title , Heavenly sword have confirmed that, Heavenly Sword will clock in around 12-15 hours of gameplay mayhem.

He confirmed this via the official forums:

12-15 hours sounds about right for a gamer well versed with fighting games. That"s just for a first playthrough - there"s also plenty of scope for replayability - especially with the stacks of unlockable content that"s been stuffed onto the Blu-Ray.
