Fish In A Barrel
Theres no gameplay involved in this "mission"; its just a cutscene. Enjoy.
Breaking The Bank At Caligulas
The glorious heist mission will begin after Carl makes his way into Caligulas. You only have four minutes to get the team into the casino, but that should be more than you need if you check your waypoints and stick to the main corridors of the building.
To begin with, hit the swipecard door in the casinos main lobby to access the secured portion of the building, then find the ventilation shaft in the generator room and chuck a canister of gas into it. After that goes down, Zero will blow the charges you placed at the dam, which for some reason were never removed by the hordes of cops that chased you away. Itll become pitch black at this point, so equip your nightvision goggles, get through the second security door, then find the door through which the van will enter. Youll need to hang a right and grab a forklift to open it.
Next up is the cash grab itself. Youll have to take the team back through the hallways, killing off all of the security guards that get in your way. There are a lot of them, but theyre shooting blind, so you shouldnt take too much damage if you keep your distance. After you get to the vault, youll have to head upstairs and blow the backup generators; use the satchel charges near the vault door if you dont have any other explosives. After that occurs, the mafia will again try to block your passage back to the truck, so itll be another corridor crawl. Just stay in front of your team and flip between your SMG and M4 to clear out everyone without having to reload.
When the team is clear of the building, youll have to work your way back through the corridors one last time to reach the roof access elevator. The enemies wont appear on your radar anymore, and the lights will be restored, so stay frosty during your trip. When you reach the roof, start jumping onto the ledges above you to reach the parachute, then jump off of the building and attempt to glide over to the helicopter across the way. This is a difficult maneuver to perform, though, so dont feel too bad if you cant make it. It might be easier to just grab a car on the ground, hit the Pay N Spray, and drive back to the safe house on the roads. When you arrive, its mission accomplished.
A Home In The Hills
If CJ wants to rule the whole damn state, hes going to have to get resituated back in Los Santos. The perfect place from which to reign is Madd Doggs crib, but unfortunately, its been taken over by drug dealers. Who better to clean it out than the states most notorious mass-murderer?
For some reason or another, youre going to have to parachute in to the mansions roof. In order to make the drop properly, youll have to blow your chute almost as soon as you leave the plane; from there, you can glide down to the rooftops without any problem. If you wait too long, youll fall short, and will have to run around to the far end of the building and make your way up the ramp.
When youre on the roof, stay back and let the Triad goons be the targets while you pop the dealers with your M4 or SMG. Eventually, more Triads will arrive, and you can storm the house.
If youve managed to get this far into the game, one would presume that you have some proficiency with the FPS-like controls, which is good, because youre going to need to use them. For the most part, you can stick behind your Triad friends and let them clear out the many rooms in the first corridor, one of which contains a suit of body armor. Eventually, though, theyll stay behind, and youll have to drop down the steps (grabbing the health restore in the kitchen) and give chase to Big Poppa, wholl attempt to leave the mansion. After this point, enemies will appear one at a time, for the most part, so just proceed slowly but surely until you exit the building.
Although your goal is listed as running Big Poppa off the road, what youre actually trying to do is destroy his car, so dont hesitate to use as much SMG ammo as it takes in drive-bys to get the job done. His car isnt any more healthy than it should be, so you shouldnt have to wail on it too much, but on the flipside, it can explode rather quickly if you manage to trap him, so be sure to get away as soon as it starts smoking and finish the job with ordinary vehicular roughhousing.
