End of the Line

End of the Line is the final storyline mission of Grand Theft Auto: San Andreas given to protagonist Carl Johnson by his brother and leader of the Grove Street Families, Sweet Johnson from his home in Grove Street, Ganton, Los Santos.

Mission
Carl and Sweet Johnson have managed to find out where former friend, Big Smoke is hiding. They drive over to Smoke's hideout in East Los Santos avoiding rioters. Upon arriving, they see that Smoke's crack palace has heavy security and there's no way to enter the place except for breaking through the wall. Carl finds a SWAT Tank nearby and steals it while being attacked by SWAT officers and Ballas gang members. He successfully smashes the wall and enters the crack palace.

Upon entering, Carl makes his way through three floors while killing Ballas, Vagos, San Fierro Rifa, Russian Mafia gang members as well as workers, whom all carry M4, AK-47 and MP5s amongst other strong weapons. Carl manages to find Big Smoke, who claims that he doesn't feel any regrets over betraying the Grove Street Families and takes out a gun ready to battle Carl. During a shoot-out, Carl manages to kill Smoke and after a brief conversation questioning Smoke's decision, he says he had no choice and saw the opportunity for power and money before dying.

Frank Tenpenny, who had been watching the whole thing, arrives and asks Carl to put all of Smoke's money in his bag. Tenpenny threatens Carl with a shotgun, but Carl distracts him by shouting "Sweet!" which makes Tenpenny think that Sweet is hiding somewhere. After he notices that he got fooled, he tries to shoot Carl, but misses. After that, Tenpenny runs to the second floor and sets the whole building on fire by shooting a generator and causing it to explode.. Carl goes the same way out and kills any gang member on his way while avoiding burning himself by the fires around the building.

After successfully escaping, Tenpenny attempts to drive away in his Firetruck, Sweet jumps on his Greenwood and then leaps at the ladder on the back of the truck, and hangs on from the ladder. Carl enters a parked Feltzer and starts to chase Tenpenny. During a long chase throughout Los Santos with rioters on the road throwing molotovs and police chasing the trio, a police officer in the truck gets out and starts stamping on Sweet's fingers. Carl gets the Feltzer under the ladder and Sweet drops onto the hood and then climbs over into the passenger seat.

Sweet then takes control of the car with Carl acting as the shooter with his Micro SMG. The chase continues throughout the city with Carl destroying Police Cars as well as rioters chasing them in cars and bikes. The chase comes to an end on the bridge going above Ganton where Tenpenny crashes his truck and after the injuries dies at the heart of Grove Street territory.

Carl, Sweet, The Truth, Kendl, Cesar together start a conversation as Tenpenny says his last words and they head inside the Johnson House to talk about their future. Suddenly, Ken Rosenberg, Madd Dogg, Kent Paul and Maccer enter the house with everybody inside drawing their guns towards them. Madd Dogg announces his first gold record and they all celebrate their success before Carl heads out of the house to see "what's happening". Following the end, Catalina calls for the last time and is heard having sex with her boyfriend Claude.

Reward
The reward for finishing this mission is increased respect and $250,000.

Trivia

 * Sweet's Greenwood is locked once Carl and Sweet arrive at Big Smoke's Crack Palace,and the player cannot enter it again during the mission.Sweet remains inside until he jumps onto the ladder of the firetruck.
 * When CJ confronts Big Smoke, Smoke pulls a Combat Shotgun. However, when the gunfight begins, he uses an AK-47.
 * Another oddity with Big Smoke is after the cutscene where Tenpenny leaves the drug lab, is that Smoke's head is under the couch, regardless of where the player killed him. He also has an AK-47 which he dropped and body armor, although this is unrealistic as Smoke's body armor is full of bullets in the cutscene where he dies.
 * In the cutscene after Big Smoke dies, Tenpenny is armed with a combat shotgun. But in the next cutscene, when he shoots the generator, he is seen with a normal pump shotgun.
 * No matter what pistol the player has in their inventory, Carl will always have a Desert Eagle when he confronts Smoke, and after he's killed Smoke. This will also be the default weapon Carl pulls out regardless what weapon the player has selected before the cutscene begins.
 * The Feltzer in this mission is bulletproof/fireproof/explosionproof/damageproof, it can be obtained by failing the mission. The license plate reads " I MY AK".
 * On rare occasions CJ will shout 'Hang on Sweet' just as he starts to chase Tenpenny.
 * It is possible to get close enough to the firetruck and attempt to hijack it although it is locked.
 * It is possible to obtain a one-carriage train (only the engine carriage).
 * The Brown Streak locomotive will be solid only when the player drives past it. Other times, other trains just drive straight through it.
 * Once the part 2 (The chase of the Firetruck) is failed, and you do the mission again, the first part (the gunfight inside the crack den) is skipped and directly to the part 2 scene, hinting that it automatically "Trip Skips" the scene.
 * The two SWAT Tanks seen on this mission are the only two in the entire game. The one used to smash the wall can be stored in a garage, however it will disappear after the mission unless the player fails the mission.
 * Tenpenny's firetruck has extreme speed, equal to a sports car rather than a firetruck. However, if you fail to catch Sweet and the mission is failed, the firetruck advances slowly and stops near Las Colinas after East Beach. You can follow it in the Feltzer and obtain it, although it goes slowly and has broken tires.
 * The player is 100% free of police attention during the mission.
 * The mission is played in three parts: The first ends when CJ kills Smoke and Tenpenny blows up the lab. The second ends when CJ exits the building and Sweet hangs on the firetruck, and the third is the remainder of the mission (chase and ending). If you had completed one or two parts and replay the mission, the first parts will be skipped and you will start from when you have failed the mission.
 * The time in this mission is prewritten. Whether or not the player enters the mission at a certain time, the mission will start at 21:30 outside Sweet's house, so the confrontation between him and Smoke is normally after midnight. Although, after Tenpenny blows up the lab and CJ is alone in Smoke's room, the time is 00:00. Concerning that the player has 7 minutes (7 game hours) to get out of the building, so when he gets out the time is around the first hours of the day. However, when he starts chasing Tenpenny, the time is 17:00, so the death of Tenpenny is around late night. The mission is finally passed in 01:15. That makes the mission considerably the longest in the GTA series, starting at 21:30 of the first day, and ending at 01:15 of the third day.
 * When the player sees Big Smoke playing video game, the joystick he's holding has no wire. It also resembles an Xbox controller.
 * There are video game machines in Big Smoke's citadel, the player can play them, but you have to make sure that you can get out of the building.
 * It is rather odd that the gangsters in the building will not try to escape the building. This is due to, unlike GTA: Vice City, the lack of NPCs being able to enter/exit buldings.
 * In GTA Liberty City Stories, when the player gets a 3-wanted level stars, the Police Maverick will say sometimes; "LCPD! This is the end of the line!", a reference to the mission.
 * The game Red Dead Revolver has a mission with the same name.
