you need to purchase the fire mode and always dunk a stunt dunk and you need to buy also
the stunt dunk......

real ****

When your 'house'meter is full,
press'L'+'R'+'Y', the character will throw the ball up
and run infront to the basket, wait for the time the ball gone down, press'L'+'R'+'Y'again
to perform the
'Bring down the house'.

I do this by myself ,
If you don't know, go to pratice in'play mode'.

just fart
