Hey, got this game today and so far so good...  Played an offline multiplayer match with a friend, but haven't been able to pull off those special attacks with the quicktime events...  Is that strictly in the adventure mode?  Thanks :)

P.S.  Cinematic moments = quicktime events... :P

Unfortunately, they're not in this game. Assuming you played the first Ninja Storm, then yes, you had to press a series of buttons to pull off your ultimate jutsu. 
 
In Ninja Storm 2, the boss battles are the only places you'll find these QT events - the Ultimate Jutsus have been changed to regular-ish attacks.

Thanks man...  Also is there a way of replaying boss fights without going through the entire adventure mode again?
