The game is feeling really easy, unlocked the secret ending and didn't realize it till later cuz I'm skipping lots of cutscenes
standing XXY+RB use it asap and time the attacks for it to work properly
up XXY+RB switch from the standing one asap, you can tap quicker or slower as only the Y matters since its the stun -> RB (instakill+regen) and if you mess with the timing they walk into the combo
back XY+RB really simple to stun kill enemies behind you
back Y+RB mc takes a step back and stuns into instakill, super easy to get kills with
you can parry and wait a sec to start the combo immediately instead of parry counter and then doing etc
Im also saying really easy but I died a lot until getting the hang of the mechanics.
+ running attack into combo also works pretty well, up XXY+RB is lightning fast.
