Million Arthur Arcana Blood is a 2D high-fantasy fighting game developed by Team Arcana and released by Square Enix for arcades (running PC-based Taito Type X3 hardware with the NESiCAxLive2 digital distribution platform) in Japan on November 21, 2017.
It is a fighting game spin-off of the Million Arthur virtual collectible card game series with gameplay similar to the studio's Arcana Heart series. In addition to characters from numerous Million Arthur games (including two new original ones), the game includes various guest characters (most notably Riesz from Seiken Densetsu 3 and Iori Yagami from the King of Fighters series).
In addition to the playable fighter, each player has three support characters (also known as Knights) to assist them in battle. Each support character has an assigned cost for balance and use restriction.
The game was later ported to the PlayStation 4 exclusively in Japan on November 29, 2018. It was also ported to the PC, with a digital worldwide release on June 20, 2019.
