How Do You Do A Critical Finish on Soul Calibur 4?

Answer 1

First you have to make your opponent block your attacks. You'll see the small diamond on the side of their health bar change color (the soul gauge), when it is red, keep slashing and eventually you'll perform a soul crush, red sparks will be visible, at that moment you have to push A+B+K+G simultaneously. The Critical Finish will be performed and you will win the battle (not the match).

Answer 2

when the soul gauge is empty (reduce it by hitting an enemys block) and smashes hit the left button (on xbox360, i dunno what it is on other consoles) to do the finisher:it will end the match with the one who diod the finisher as the victor, regardless of health
