Campaign mode is not very long at all; it consists of 41 total fights. There are five cities that contains eight battles each, with one of them having a ninth and final battle at the end.
Tips: Make sure you string special moves back to back for maximum effect. Try to dodge incoming attacks, and use your combo breaker if you're ever caught in your opponent's combo. Once you get the hang of playing, fights typically last 30 to 60 seconds.
Note: This achievement may be glitched, so before your last few fights, I highly recommend that you create an additional save on a separate memory device, like a flash drive. This is so you don’t have to complete the whole campaign over in case this doesn't unlock for you. Also nets you 40 UPlay points
