WTMG’s Leo Faria: “The awfully-named Under Night In-Birth II Sys:Celes is a pretty good sequel to what was already a really deep, but surprisingly accessible 2D fighter. In terms of content and mechanics, this game is still excellent, worthy of being put right next to other Arc System Works fighters. In terms of presentation, it didn’t exactly reinvent the wheel, but it’s not like the other games in the series were ugly to begin with. Sadly, in terms of how well this particular PC port was crafted, well, I was a bit disappointed. With a handful of glitches and an overall sensation this port was treated like an afterthought, you are better off playing it on a console.”
