Basically:
LT = Block
RT = Attack
Hit RT once, attack with right hand. Hit RT again, attack with left hand. So basically if you're spamming RT it would alternate between your right and left hand. Holding RT would do a one-handed power attack like how it currently is in the game, and holding both LT/RT would do the 3 hit combo that's also currently in the game. Holding LT would Block and tapping RT while blocking could elbow the enemy, which could essentially stagger them, akin to power bashing with a shield.
They literally already have every animation in the game already, all they would need is to add a blocking animation and elbowing animation and change the controls for unarmed combat...wouldn't be that difficult for them to implement it honestly if they wanted to, but I don't see it happening. Hell, they don't even have to do the elbowing thing, RT while blocking could just be a quick jab that staggers them as a "shield bash-esque" move if elbowing them is too hard to properly animate.
