Melty Blood: Act Cadenza was the first arcade port of the series and was published by Ecole Software. The visual novel was removed, while the Arcade Mode dialogue featured in Re-ACT returns. It completely revamped Aoko Aozaki's movelist for use as a playable character, and introduced Kouma Kishima into the series, a man who was deeply involved in Shiki Tohno's past. It also introduced the Shielding mechanic (separate from EX-Shielding), as well as including various changes to the properties of characters. This version (as well as the later released Ver. A) can be identified by the Atlasia crest, and the phrase "Through the Looking-Glass, Black Light transparently", both present in the logo. Melty Blood: Act Cadenza, released for the PlayStation 2, was unique as a port in that it included an option to revert to Version A mechanics, yet introduced significant changes that were later included in Ver. B, including an early version of Neco-Arc Chaos as a hidden character. It is sometimes known as "Ver. A2".
