OG Loc is a mission in Grand Theft Auto: San Andreas, given by Big Smoke to protagonist Carl Johnson from his house in Idlewood, Los Santos, San Andreas. This mission is one of few that use the Trip Skip feature.
CJ drops by Big Smoke's house and waits for him, but instead him and Sweet appear from the backdoor. The trio drive over to the police station in Pershing Square to pickup Grove Street affiliate, OG Loc. Upon arriving there, Loc says that he needs to kill some members of the Los Santos Vagos, Freddy, who has disrespected him in the prison and stolen his "rhymes". They agree and drive to East Los Santos where Freddy lives. CJ decides to stay with Loc but Smoke and Sweet drive off home.
After a short conversation Freddy, he jumps on a bike and escapes from the other door of his house. CJ and Loc jump on another bike and starting chasing after him through the streets of Los Santos. The chase comes to a stop at Idlewood outside the Basketball Court. OG Loc and CJ kill all the Vagos gang members as well as Freddy. Loc then says he needs to sign for a job at the Burger Shot in Marina. Carl and Loc ride a vehicle and head to the restaurant.
Note: If however, Freddy is killed during the chase, then you will still watch the same cutscene at the basketball court.
