I just played the story mode and 2 local fights, but I'm gonna focus on the story mode, and no I didn't play the online stuff. It's a bunch of cutscenes with an okay plot and obviously: a fight. But it has a serious problem! The difficulty gets higher through the chapters, what it means if u put it on a medium level, like me, at the end you'll have a hardmode fight and will have to lose 3 times until u get it right. Also, there are 12 chapters with about 10/9 characters you'll have to stop and learn their combos, so, m a y b e It'll be even more difficult. In general, an okay game, if you have it on your backlog, give it a try, but It's not something I'd recommend you to buy
