Catalyst is a mission in Grand Theft Auto: San Andreas, given to protagonist Carl Johnson by fellow Grove Street Families member Ryder from his home in the Grove Street cul-de-sac in the Ganton district of Los Santos, San Andreas.


Carl pays another visit to Ryder, who is making his own "water" after he couldn't find it in his backyard. While Carl and Ryder are talking, Tenpenny and his accomplices drop by to inform the two that there will be a army munitions train passing through town shortly, and that enemy gangs such as the Ballas will try to raid the train.

The two immediately depart, arriving at the train only to find the Los Santos Vagos have ambushed the train first and are attempting to offload munitions fighting the Grove Street boys. Once the Vagos are dead, the Ballas show up and try to take the train. Not wanting to lose the munitions, Carl jumps on the train. Ryder is now in the back of his Picador, who waits with a Grove gangster driving behind the train, with Carl throwing some boxes to him. After acquiring sufficient munitions, the two are pursued by the police. They go to the nearby Pay 'n' Spray to lose the cops, and goes back to Ryder's home.


Carl Johnson: Hey, Ryder? What the hell you doing?

Ryder: Nigga, I couldn't find that wet I buried, so I'm making my own. It's easy, fool.

Carl Johnson: Oooh! That's strong. Man, don't do that! You'll sauté the both of us.

Frank Tenpenny: Morning boys!

Ryder: Man, who you calling a boy, fool?

Frank Tenpenny: What should I call you? Midget?

Eddie Pulaski: How about prick?

Frank Tenpenny: Prick...

Eddie Pulaski: Yeah, prick works.

Ryder: Man, fuck you.

Frank Tenpenny: Bitch, get outta here. Mmm... Smells good. What's cooking? Where's mine?

Ryder: Man, just chill out, a'ight. Move. Here. Don't be sweating me, motherfucker.

Frank Tenpenny: Mmm, my wife loves this stuff, man.

Eddie Pulaski: *laughs*

Frank Tenpenny: Anyway, there's a train gonna make an unscheduled stop just down the way. Its got a, how you say, "little something something" on board for you boys. Square business, man.

Eddie Pulaski: Catch you later, homeboys.

Ryder: Asshole.

Frank Tenpenny: Oh Carl, try not to kill any more respected police officers. Please?

Eddie Pulaski: Crime has certainly gone up since you got back, kid.

Carl Johnson: Just doing my part for the community.

Frank Tenpenny: Your train's gonna be there in five.

(Carl and Ryder, once gone back to Ryder's home)

Ryder: Damn, homie, your stuff was tight!

Carl Johnson: You too, homie!

Ryder: LB's coming over to stash the shit.

Carl Johnson: Okay, later then.

Ryder: For life, CJ, for life - you heard?


The reward for this mission is an increase in respect. The mission Robbing Uncle Sam is unlocked.


  • According to this mission, Tenpenny has a drug addict wife, though due to his tone of voice, Tenpenny could be joking.
  • The song heard in the pre-mission cut scene is Fantastic Voyage by Lakeside, this song can also be heard on Bounce FM
  • If the player kills Ryder before climbing on the back of the train, you won't be able to steal it - even if the mission is failed, it will remain locked.
  • The freight in this mission has only one car attached, which is the only time this occurs in GTA San Andreas.
