Arcana Heart 2 is the sequel to Arcana Heart. It was the first game in the series to be developed and published by Examu after the rights of the franchise had been transferred to the company from Yuki Enterprise. It was also the first game for Examu's proprietary eX-BOARD, an arcade board based on Windows XP Embedded that would become the standard platform for the rest of the series and other arcade games published by Examu. The game features 6 new fighters, each with their own unique Arcana. New techniques were also included, such as the Arcana Blast, allowing the player to become temporarily invulnerable, Arcana Homing, a feature allowing the player to simultaneously close the distance between them and the opponent while homing in on them, and the Critical Heart, a devastating special attack unique to each character.
