The demo features two teams - Team K' (K', Kula, Maxima) and Team Fatal Fury (Terry, Andy, Joe) - and two stages (London, Airship), designed to show off the game's artwork and design. The demo will also offer online play.
The press release also reveals that a patch is currently in development to improve the game's online functionality. There is no release date for the patch yet, however, and Atlus states that the patch contents will be revealed at a future date.
The King of Fighters XIII was released on the 25th October in North America and the 22nd November in Europe for the Xbox 360 and PlayStation 3.
