There are a couple of videos below; the first is a trailer showing off the new Fight Lab mode, which lets you "train and master your skills through a series of mini-games" while playing as Combot.
You'll also see how you can modify your Combot's appearance and, for the first time, his move set.
The second video is a 20-minute-long tutorial showing off some basic techniques to begin with before delving into the more nitty-gritty tactics. It's part-one of a series, so we expect it'll get pretty hardcore, and will be a good one to follow if you want to be an advanced fighter.
