Bullseye's One-Hit Kill
The way you pull this off is similar to the Energy Drain move, but instead of pressing Left Punch, press Right Punch.
(Facing right) the move would be: right, left + 'right punch'. Bullseye's fist will start to glow and he will spin around and (if the opponent's
too slow) he will chop off the opponent's head.
First Person View
While fighting hold L2 + R2 and press the direction opposite the direction your player is facing. It should say FIRST PERSON FIGHT
CAMERA ON or something like that. To turn it off hold L2 + R2 and press DOWN.
Sabotage's One-Hit Kill
