Combo

Combos can refer to either how many consecutive attacks you can perform that forms as a number in the top right of your screen, or the assembling of moves to make a longer, inescapable one (ie. Gattling Kick, Backflip, Frontflip) The amount of hits in a combo does not affect the damage or any bonuses you may recieve. It is thought to increase experience gained in story mode but that is still yet to be proven.
