Street Fighter IV brought the 2D sprite fighting game art style nicely into a world of 3D models and swooshing cameras, but deary me the transition in Guilty Gear Xrd -Sign- [official site] is amazing. Developers Arc System Works took a few years longer than Capcom to switch their series to 3D, but ended up with a game looking a whole lot like, well, hand-drawn art. Now it's coming to PC real soon: tomorrow.
Arc have also announced PC releases for four other games, some they made and some they're publishing: sports compilation River City Super Sports Challenge -All Stars Special- plus fighting games BlazBlue Chrono Phantasma Extend, Under Night In-Birth Exe:Late, and Melty Blood Actress Again Current Code (what a name!).
So, Xrd's art. It's 3D, but looks a lot like really hi-res 2D until cutscenes or fancy moves break out different camera angles. It's even animated in a way similar to hand-drawn sprites, with a different pose each frame rather than interpolated movements. Check out this GDC talk from technical artist Junya C Motomura if you're curious.
Xrd -Sign- will be on Steam tomorrow (or very early Thursday morning, for us). Arc have already announced a follow-up for consoles but heck, they're finally catching up!
As for the other games, River City Super Sports Challenge -All Stars Special- will arrive later this month, BlazBlue Chrono Phantasma Extend [official site] is due in February 2016, Melty Blood Actress Again Current Code in spring 2016 (I believe it's already on PC, but not translated), and Under Night In-Birth Exe:Late [official site] in summer.
