Atlus and SNK Playmore have announced the availability of a demo for The King of Fighters XIII. The demo, which is now available on Xbox LIVE Marketplace (initially only for Gold members) and will release for PlayStation Network on 12/13, offers fans two teams–Team K’ (K’, Kula, Maxima) and Team Fatal Fury (Terry, Andy, Joe)–and two stages (London, Airship), showing off the game’s breathtaking artwork and providing ample proof that KOF XIII is the best playing game in the 15-plus year history of the series. In addition to its generous roster, the demo also offers online play, giving fans an opportunity to try the demo with friends around the country. Also today, Atlus and developer SNK Playmore confirmed that work is already underway on a patch that will further improve the game’s online functionality. Details regarding the update’s content and release timing are not yet available, but additional information will be released as soon as possible.
