Grand Theft Auto: San Andreas Walkthrough

With Madd Dogg beginning to get his life back together, CJ and the gang decide that the casino game is too limiting and they need to expand their interests. Madd Dogg is the way back to the top. The only problem? His old stomping grounds have no been overrun by Loc. Time to take it back.

Once you take control, you'll parachute from the sky to clear the place out. Freefall for a bit and then glide down to the helipad on top of the house, toward the red flares. It will be marked by a yellow blip on your radar.
Once you land, several gang members will attempt to make their way up. Kill them all.
If you need body armor, a vest will be waiting for you near the helipad landing, behind the air conditioning units.
Once they're dead, make your way inside by heading to the yellow blip on your side.
Kill the guards immediately inside the potted plant area and then the others down the hall around the corner.
As you pass down the hall, be sure to check each room, as each one will contain at least one guard ready to fire at you. Another body armor is also located on the 2nd room to your left.
Once you've made your way through the hallway, head downstairs and take out the semi-circle of gangsters waiting for you. More guards will flank you from both sides at the bottom of the stairs. If you need additional health, make an immediate left at the bottom of the stairs to find the kitchen, where a heart will be waiting.
To your right, you'll see your target Big Poppa, marked by a red blip. Chase him through the mansion and kill him.
Take out any guards along the way.
Now that you're outside, you'll have to chase him down by car.
Take the car near the carport and follow Big Poppa, who's still marked by a red blip on your radar. Run him off the road and kill him any way you can. Once you do, the mission is yours.
