I was really finding this hard as I am awful at beat em ups. I've tried many of the other guides which are great between, but they was more complicated
then they really needed to be lol. The Jack-6 method is ok, but if you want the far easiest method, then Devil Jin is the character to go with. If in doubt, read this solutions comments and see what other people think of this method.
- Put the game on easy, single round.
- Select offline arcade mode
- Now play through arcade mode until you get the bonus fight with Nancy
- Plug in a second pad. If it looks like NANCY is going to KO you, hit start button on this pad. This will initiates a Challenge, beat the challenger and then after, it will give you another shot at the bonus stage (Repeat as many times as you need)
Beware if you hit start after KO in Nancy stage, you will have to start all over from the beginning again.
- Now use DEVIL JIN
- At start , get as close as possible to Nancy, and keep spamming
over and over. It's that simple!
Don't worry about side stepping, as this move will do it for you.
It took me two attempts personally.
Have a try and let me know what you think
