Clive Barker's Jericho developer Mercury Steam is currently at work on a new third-person action-adventure title named Lords of Shadow, publisher Konami announced today.

In development for PlayStation 3 and Xbox 360, Lords of Shadow is slated to arrive in 2010. Taking place in Southern Europe during the middle ages, the title is described as a "dark fairy tale" that focuses on "one man's journey to discover the true meaning of sacrifice amidst murder and betrayal."

Along with puzzle-solving and exploration elements, the title sports a weapon system, dubbed "Combat Cross," that allows a single weapon to perform a number of functions. For example, the Combat Cross can go from a stabbing weapon to a defensive device.

"Every element of the game pushes the host hardware to its limits," said Konami product planning head Dave Cox. "It is truly an epic game but telling a human and emotive story. This is a title we hope will set a new standard for action-adventure titles."
