Now Available: King of Fighters XI

The King of Fighters XI (KOF XI) is the latest installment of the King of Fighters series. The character roster has received a major shake-up. For the first time ever, recurring characters Mai Shiranui, Leona Heidern, and Joe Higashi have been dropped from the roster. Eiji returns; though a secret striker in KOF 2000, he has not been a playable character since KOF 95, the ever popular Duck King makes his first real appearance in the series, and Bonne Jenet crosses over from Garou: Mark of the Wolves. Three characters are original to The King of Fighters XI: Oswald, Elisabeth, and Momoko. Elisabeth is the heir of a noble French family, Oswald is a fighter from Ireland who utilizes cards as his weapons. Momoko is a young capoeira fighter from Japan accompanying Athena Asamiya and Sie Kensou on the Neo-Psycho Soldier team. Arcade rooms are receiving competition massively worldwide at this moment for this game
The numerical distinction for the series now is based primarily on SNK Playmore wanting to have a more sporadic and unpredictable timeframe for development for the series.
