From the creators of Melty Blood. 2D fighting games are going through a renaissance this decade. This one looks like it could give BlazBlue and KOF XIII (Both games I'm very fond of, btw) a run for their money. A newer character, Vatista, looks like a shout out to Nu from BlazBlue, being a mecha musume of sorts like her.
Promotional and some gameplay:
