WHAT ABOUT A BRUTALITY MODE IN GAME??

i mean that during the fight more you do combo (or something else...) more you gain power (maybe it appears on an energy power bar on the screen like for the life, as in the street fighters games....) then you can execute a brutality which is NOT a fatality but just a super move that make your character more powerfull and the enemy loose more life (then you can maybe perform a fatality), and why not the combinason of the two (brutality then fatality) will give you more koins or points (for unlocking kontents)...

So the brutality will not lead to the death (as in old MK) but is just see as a super mode for your character who will become more powerfull for a little moment making the kombat more violent, and it's add a strategic element to the fight.

What do you think?
