that is weird all you do is follow the directions
For naruto, you beat b rank missions.
after you go to options, go to ninja card.
You beat 50% of the missions and missions 1,3 and 10...i think
By beating the whole game and missions its easy
beat story mode and finish all the missions
YOU HAVE TO BEAT ALL MISSIONS (INCLUDING S RANK MISSIONS) AND THEN BEAT KASKASHI GAIDEN WHICH YOU WILL THEN UNLOCK ITACHI, KISAME AND THE 2 SURVIVAL LEVELS
first u gotta beat all ur original missions :3 b4 flashback
Doing missions on Naruto-Arena is very easy. They are not part of the game, but run in the background. First make sure your ninja rank is correct with the mission rank. Ex: Be a Genin to do a Genin mission Then, look at what you have to do on the mission. Ex: If you need to beat 12 people with Sasuke, put Sasuke on your team, then beat 12 people through ladder matches or quick games.
After you beat pain you can do all of the side missions and after a bunch of these missions you get the chance to play as taka Sasuke and fight against Killerbee, the eight tails wielder
once you beat orochimaru with naruto you beat the game
you have to beat story mode on difficulty two and then its in the shop for 10 or 20 thousand ryo.
well its just a shock to me i finally just discovered it. Its really kinda easy just beat ultimate nine-tailed naruto and 2nd state sauskes final missions and score "hokage"......ps: it will also be wise to complete both characters first 2 missions and last 3 missions
