REWARDS - Respect
Every other mission, prior to this, needs to have been completed, including all of Big Smoke's missions, Ryder's missions, Cesar's mission, C.R.A.S.H. missions and OG Loc's missions. In addition, a certain level of Respect is needed, so if you need some, then take over some territories.
Get into the car and head for the yellow blip on the radar. Oh boy, all hell has broken loose now as the police raid the meeting. Smoke and Ryder get the hell out of there, while CJ stays to save his brother. You can take out cops outside if you want, but it's probably better if you just hurry up and head inside. If you need any health, you can purchase drinks from the vending machine once you're inside the motel.
Head upstairs and take out the first cop. Head down the hall and take out 3 more cops when they show their face. If you again need health, go into the room with the hooker and she'll replenish your health. Keep going down the hall and you'll come to a room where more cops will drop down from the helicopter through the skylight. Armor is on the second floor in this little area, provided you need it. Keep pressing forward, killing the cops until you get to a hallway where some cops will drop through the vents from the ceiling. In this hallway, in the second room on the right, is Sweet.
CJ and Sweet try to escape by means of the roof, but a chopper will be blocking their way. You have to protect Sweet from the cops on both sides of the chopper shooting down at him. Target them first and take them out, then keep firing at the chopper to knock it out of the sky. Once you down the chopper, follow Sweet to the streets below.
Smoke and Ryder pull up and you jump in. Next comes a rail shooting part. The cops continue their chase and someone hands you an AK-47. Smoke is driving the car and you'll have to shoot at the cops. Pay attention to what your friends say; if they say to watch your left, then you better watch your left.
After a while, motorcycles will join in the chase. Some of the cycle cops actually leap onto your car, so hurry up and blast them off. When you get to a roadblock, your gun jams up and Smoke continues driving. Watch the rest of this exciting sequence of events, then the mission will be complete and you'll earn some respect.
