let me clear that up a bit, i just finished doing a 1389 hit combo, no damage% to tell due to the fact that it no longer even shows up for that much, all im doing is attack 1,1,1,1,1.... while player 2 is against a wall

You mean you were actually bothered to hit the attack 1 button 1389 times in a row

I thought the moment you took your opponents health below 0, the game cut off your combo so you could perform a fatality?

I need to complete Raidens last combo in Konquest before i can play as mokap and blaze.. i would like to see this combo in action though.. would be quite funny.

He most likely did this in practice mode. And, the when the opponent hits the wall, that counts as a hit in a combo, so he probably only hit 1 some 600-odd times.

You can also do it with Sonya. Have her Kali Sticks out and your opponent directly against the wall, and keep doing Back + 3, and again as they're falling to the ground. The hits rack up forever if you can keep it up.

And yes, the hit percentage for some reason moves down the screen the more hits there are.
