Beat the game with full health, no power ups.
Question is...why are achievements locked?
I figured that there was some means to unlocking them, but nope.
Funny thing...
taking zero damage through out the entire match took me 27 tries...lol
Yea, its that good and was worth the play :-)
The ending was something to be desired though...shoulda had Ryu stab him in the heart first, then behead him...or do an "omnislash" ;-)
