Boss Battle: JETSTREAM SAM
Unfortunately, the fight against Jetstream Sam is extremely easy. Most of his attacks can simply be parried/blocked, and by now you're practically a master at this. The only attack you really have to watch out for is his sword stab. His sword will flash yellow and it's best if you timely dodge this. You'll enter Blade Mode around halfway but the rest of the battle is monotone. When Sam is down to 0.1% of his health he'll perform a strike that triggers a QTE (Y+B on Xbox360, Triangle+Circle on PS3). Enter Blade Mode and the fight ends if you successfully strike his sword out of his hand again.
