Any time Arc System Works announce something about Guilty Gear on PC, I hope it's them bringing the gorgeous (and ridiculously-named) Guilty Gear Xrd -SIGN- our way. Xrd sent the fighting game series from gorgeous hand-animated sprites to gorgeous hand-animated 3D, looking a squillion times better than Street Fighter IV. Seriously, watch this GDC talk about its style.
Anyway, no: it's not that. Arc are still a few years behind on PC, though today they're another step closer to caught-up with the PC release of Guilty Gear XX Accent Core Plus R [official site].
Accent Core Plus R is the fifth version of Guilty Gear XX, benefiting from a decade of new characters and modes and moves and levels and balance tweaks and goodness knows what else. It's got nineteen characters, eight modes, and, yes, online multiplayer.
It'll launch through Steam tonight. After that, Arc's PC offerings will only be behind two BlazBlue games and one pretty pretty Guilty Gear Xrd (I think? Arc have such tangles of revisions that I could be missing a dozen). Ye olde Guilty Gear X2 #Reload is half-price on Steam right now too, if you're not a giddy goat like me bleating for the newest and shiniest. I would be so very happy if Persona 4 Arena came to PC too.
Anyway, for now, have a trailer:
