At the battle,use this combination:
Back(Hold 2 sec),Forward,Back,Forward,KKK
When you use this combination,Shadow Lady will perform a Super Attack.It's called "Final Mission".When you use it,Shadow Lady catchs her opponent,throws him air,and makes 15+ hits(Like Akuma's or Evil Ryu's Shun Goku Satsu).If you use it,your opponent will be damaged too much.
P.S.:You must have 3 Levels at your Vitality Gauge for use it.
when at arcade, put the cursor over ryu, hold select to get kens transformation, hold start to get evil ryu's transformation.
