-Power Blow is H+P+K
-Wall Crumple is like in the Akira video where you get a guaranteed follow-up hit.
-Side Steps are 22H+P+K and 88H+P+K and you can do side step attacks during.
-The limbo stun is back!
-Izuna drop hold is still there for High, Mid and Low. It's an "advanced" hold, i.e. the first input is 67H for High, 64H for Mid and 61 for Low. This also does not counter kicks at those levels.
-Offensive holds have been removed from the majority of the cast here. Hayabusa's handstand throw still appears to be an offensive hold.
-Hit bubbles/effects can be turned off.
-The button config lets you select a function and then hit the button you would like to assign.
-You can choose between classic and action camera types which just vary the camera during throws.
-Hayabusa has gained an air throw: 41236H+P
-Normal Life is now 270 points versus the previous 240. This is was considered the Large Life setting previously.
-Standard Throws have been sped up back to 5 initial frames
