REWARDS - Respect, $12,000
NOTE - This mission can only be started between 20:00 and 6:00 on the in-game clock.
Cesar hands you a gun with a silencer on it before you head out. How nice of him to do that. Grab a car and head to Jizzy's club. When you arrive at the club, the security at the front door won't let you in. Not a problem for CJ. It might be helpful to either blow up Jizzy's car or shoots its tires out.
Head towards the bridge and use the scaffolding to get on top of the club (you'll have to jump down when you get above it), then go into the club via the skylight. Go from the rafters and find the steps leading downstairs until you get to the main floor and trigger a cutscene. Jizzy makes the call, but CJ shows up and shows him his true colors.
Jizzy escapes from the club and you'll have to give chase with his guards and girls firing at you inside the club. Kill the gunmen and exit the club via the front door. Jizzy escapes in his pimpmobile (he uses a bike if you blew up his car), so get into any nearby car and start chasing him. Do drive-bys until his car explodes, then kill Jizzy if he's still alive. Once Jizzy is dead, pick up the phone and CJ will automatically call Cesar and tell him to meet him at Pier 69.
