GOOD GOD! TERRIBLE!
The actual fights are the one redeeming quality of the game. You fight as 20 of the series characters and can use a heavy, light or chakra attack. Chakra attacks are powerful attacks, which I will go over later. The heavy and light attacks are easy enough to pull off by mashing the Y (Heavy) and B (Light). The chakra is pulled off by hitting the A once you have filled the chakra bar. However the one downside to chakras is that some are overly powerful (with no other downside to the characters) and some are weak as **** For instance the one person who has 2 chakras (everyone has 1), Naruto has a **** chakra in the beginning and at the end he gains this godly power which takes away 3/4 of the opponents health.
Overall i got to say, stick to DBZ or something that has a proper story and balances its characters a little more.
