All you have to do here is drive Sweet from the mansion to Grove Street. The eponymous riot is ongoing, though, so be careful for exploding cars.
Cesar needs you to help him clear out the Vegas out of the barrio. Theyve fortified their position pretty good, but this is still just another corridor crawling mission; go in with plenty of ammo, full health, and a set of body armor, and you should come through just fine. The only scary spot is the enemy with a rocket launcher at the end, but so long as you dont move after you spot him, he shouldnt be able to hit you.
After this mission, Sweetll tell you to roll out and take over some more territories. Hope you like the gang war mechanism, because youre going to have to get Scarface on those punks for an hour or so of playing time before Sweet finally hits you up on your cell phone and lets you know that hes located Smoke. Note that the already omnipresent police force is now even more densely stuffed onto the streets; even a single star will thus mean that youll have nonstop harrassment from the cops when youre on the street. Note also that the cars and vehicles on the streets are weakened, and will explode very easily; in most cases, the best vehicle for you will be a police car, should one roll up and the driver gets out. Other than that, a bike makes a surprisingly useful ride here.
End Of The Line
Time for Big Smoke to die. Grab the SWAT tank (approach from the south, or the Ballasll blast you), then ram through the wall into Big Smokes Crack Fortress. Apparently hes built quite the empire while you were out of town, and now resides on the top floor of a full-fledged crack factory. Youre gonna have to bust in there and shut the place down, much like Robocop.
On the first floor, you dont have much to worry about, save one huge room full of crack fiends. This occurs just after you see the first body armor pickup, so if youre near full on the armor, save that pickup until after you clear out the next room. Theres also a health pickup and an automatic shotgun in a small room near the doorway leading to the next floor. The next couple of floors are similar affairs; just blast through the baddies, keeping your back to a wall, and check all of the rooms for extra health and armor.
The top floor, as mentioned, is Big Smoke. Hes got body armor on, so he can take a bunch of damage, and the lights will go out while your fighting, making it difficult to see. Hell also call in some backup during the fight, so keep an eye open. Although the game tells you to aim for other parts of his body, you can still kill him with bodyshots, and this is probably the preferable way to do it; just get into a corner, lock on to him with your M4 or AK, and hold down the button until he drops. If you enter the fight with most of your health and armor intact, you should be able to take him down without a problem.
Tenpenny arrives afterwards; apparently you will be able to kill two birds with one stone. As he leaves, he sets the building on fire, so youll need to grab a fire extinguisher and use it to douse any flames that are in your path. You have extra time to work with here - even a leisurely pace should get you ou with a minute or so to spare - so buck down all the fools in your way and get out of the building. If youre running low on health or armor, feel free to check the side rooms along your path.
Tenpenny takes off in a firetruck when you reach the street, with Sweet in tow. All you can do for a long time is follow along; eventually a cop will start pounding on Sweets fingers, and youll have to drive underneath him to pick him up. Thus begins the final portion of the game, another rail-shooting mission. You wont be able to damage the firetruck, so concentrate on the cop cars and motorcycles that follow along. When Tenpenny finally crashes, hell check out and you can watch the credits roll. Of course, if you skip past the credits, youll be able to continue on with CJ and attempt to do any side missions that you avoided on your first play-through. One of the notable changes to the game world is that Torenos house to the west of San Fierro now houses pickups for all four of the games heavy weapons, so if youre looking for heat-seeking missiles or a minigun, head out that away.
