On the main menu, choose the top option. Two options appear. Choose the bottom one. Those are partner episodes.
Beat the following partner episodes:
Smoker Nami Zoro Usopp Sanji Chopper Robin Franky Brook Luffy Aokiji Hancock Kuma Mihawk Crocodile Buggy Hannyabal Magellan Ace Garp Jozu Marco Vista
This will unlock Whitebeards partner episode. Beat it to get a new mission for 4-2 called "Whitebeard's rescure mission". Beat the mission and you will unlock Whitebeard and Trafalgar Law as playable characters and final act 1.
Dynasty Warriors 8 has been announced. Looking forward to it and hoping for a handheld version.
it is simply side story where the character of the partner story will be the boss with several others as additional enemy. if you put sanji partner story, sanji will be the boss with additional other crew members as enemy.
I did all those things and I beat mission 4-2 rescue whitebeard, and after i beat it nothing happened, did i not fulfill a condition in the mission?
Are you sure? Because i get both players unlocked in my first try, just beat the mission and not fight Shirohige, just kill the other ones (red faction) and eventually i got the cinema of the rescue of Shirohige.
