End of the Line
End of the Line is the final mission in Grand Theft Auto: San Andreas. It takes place after Los Desperados.
Summary
It begins with Carl going to Sweet's house to get Big Smoke for his betrayal. The two manage to locate Smoke's fortress. However, Carl decided to get Smoke himself in order to avenge his mother's death. Carl steals a SWAT tank to force his way into Smoke's fortress (this is the only time in the game that CJ has the oppurtunity to steal a SWAT tank). After Carl reaches the entrance to the place, he reaches the other floors in order to find Smoke in the top floor of his fortress. Once he reaches Smoke, a gun fight ensues. In the gun battle Carl kills Smoke.
Once the fight is over, Frank Tenpenny goes to the fortress to ask Carl into giving all of Smoke's drug money to him. Tenpenny tells him that he attempted to escape the riots by using a plane. He prepares to kill Carl until he shouts "Sweet!" which scares Tenpenny and he misses the shot. Tenpenny then, causes an explosion at the drug lab, hoping it would kill Carl in the blast. Carl manages to go back all the way through the crack palace where he sees Sweet jumping on Tenpenny's firetruck in order to catch him. Carl chases the truck and manages to catch Sweet. Carl begins to take down the rioters and Vagos from behind while Sweet drives to catch Tenpenny. When reaching a bridge, the fire truck crashes down right at Grove Street's heart. Tenpenny gets out of the damaged firetruck but injured from the crash and dies from it.
Full Walkthrough
Before taking part in this mission you must go out and battle the Ballas and Vagos to win at least 35% of the territory in Los Santos, so get moving. You'd be surprised how many you actually need to take in order to get that number, if you haven't been working on it previously you're looking at between fifteen and twenty territories. When you've got enough Sweet gives a phone call telling you that he's found where Smoke is hiding and you are ready to start.
When you drive off to East Los Santos Sweet stays inside the car and watches you while Carl has to steal a SWAT tank in order to smash through Big Smoke's crack palace because the security has locked the doors due to riot. To make it easier use a sniper rifle and shot the Ballas and SWAT team and ride with the BMX to the tank. There's no reason to get out right away, use it to kill all the Ballas inside before you're forced to disembark and head through the door. You need to start making your way up floor by floor. On the first floor there's a few guys in the hall and some body armor just behind the door to the first floor. Get ready for a huge firefight when you go through the nearby door. Crouch down and fire from behind a set of boxes. Run through into the small adjacent room and eliminate the two guys in there before ascending the stairs.
On the second level before going through the door you can find a full health item in the room that overlooks the one you just fought in. Watch out for exploding barrels in the large drug lab on the second floor, use them to your advantage don't find yourself next to one that's being targeted because the workers have strong M4's. A full health item awaits at the top of the stairs (you have to run around the upper walkway) and the next set of stairs leading to the third floor. You'll find the same piece of armor you've come to expect. You need to watch your back in the lounge, not only should you check both left and right when going through the door, make sure the first guy you target is the one with the shotgun because one shot can take away half of your armor/health. In the hallway that follows the room with two couches, make sure to check both rooms that the Russian Mafia's jump out of for a body armor and health refill. After this floor, it's time to go up and get Big Smoke.
Big Smoke has some powerful body armor so you're going to need to aim for his head if you want to do serious damage. It's not really necessary if you're using something like an assault rifle, just blast away but make sure you take out his lackeys first. When the lights go out run to the corner and grab the thermal goggles, you'll also find a drink machine over there if you get thirsty during the battle. Eventually Smoke will go down and a scene begins, but it's not over, no sir. A countdown begins and the building is burning, no here's the classic predicament. You're given a time limit but enemies still populate the building. I'll tell you now that being careful and making sure it's safe before proceeding will still leave you with two minutes or so when you get out of the building, so don't go nuts and make a mad dash. Make sure you clean out each room before going any further and note that the body armor at the top of each set of stairs has respawned. When extinguishing flames remember to aim at the base of the flame and don't swing it around, be consistent. If there are two sets of flames blocking a door you should only need to douse one of them to get through, exit the building for a scene.
The final task is a chase, you'll automatically start in the car so chase after the firetruck. You don't need to attack it, in fact it's strongly advised not to, you'll have your hands full keeping up anyway. People around the city are throwing molotov cocktails like crazy but it's more of a light show than anything dangerous, you'll probably have driven through a hundred fiery explosions before the chase is up and your car will still be just as shiny. At some point you'll get a message at the bottom of the screen. Before the bar runs out you need to drive forward and get under the ladder so Sweet can drop into your car. Now it's a little change up and the very last thing you need to do is a little shooting on the back. Fire upon any cop cars that are chasing you, any bikes and such. Make sure to take out the two cops on the fire truck, when the one of them dangles from the ladder he's dead, you don't need to keep firing. After quite a chase assuming you've kept the cops at bay you'll be treated to a couple final scenes and then the credits roll.
