Almost three years after the release of KOF XIV, SNK announced King of Fighters XV is now in development. The revelation was made after SNK introduced additional characters coming to Samurai Shodown, including Mina Majikina for Season 2 DLC coming in 2020.
The short teaser for King of Fighters XV starts out with “Evolving to New Heights” before its logo appears, followed by the “Now in Development” message. No other information was revealed about KOF XV.
The announcement of KOF XV comes as the franchise turns 25 this month. The first game in the series, King of Fighters ’94, made its worldwide debut in arcades on August 25, 1994, followed by a Neo Geo console release on October 1, 1994.
