The Hardest Mission in GTA San Andreas, Explained
"Hardest" is subjective, but San Andreas has a near-unanimous answer — and it isn't the one everyone memes about. Supply Lines vs Wrong Side of the Tracks, and the real contenders.

The Las Venturas Caligula's Casino arc is the first proper Rockstar heist sequence — predating GTA V's by nearly a decade. Here's the full walkthrough.

The 100% completion flag in San Andreas requires every mission, every collectible, every school. Here's the complete checklist for the most ambitious GTA completion run.

Ask which GTA San Andreas mission is the hardest and you'll get two answers, and they're not the same mission. One is the one people quote. The other is the one people actually couldn't beat. The community consensus — and most "hardest GTA mission ever" rankings, including WatchMojo's — lands firmly on "Supply Lines...", not the famous train one. Here's the real answer, why, and the genuine runners-up.
"Supply Lines..." is part of Zero's strand in San Fierro — the missions for the eccentric RC-shop owner. The task sounds trivial: pilot the RC Baron, a tiny radio-controlled plane, and destroy all of rival Berkley's couriers around the city before you run out of fuel. It is, by wide agreement, the single most difficult mission in the game, and it earns that for four specific, stacking reasons:
The mission's reputation is so entrenched that even David Cross, who voiced Zero, has said he found it nearly impossible — a fitting footnote for the mission most retrospectives name the hardest in any GTA. Later releases tuned the experience somewhat (control schemes differ across the PS2, PC, mobile and remastered versions), but on the original game "Supply Lines..." is the wall.
The mission people think is the hardest is "Wrong Side of the Tracks" — early in Los Santos, with Big Smoke. CJ drives a bike alongside a moving train while Smoke, riding pillion, shoots the Vagos on the flatcar. Fail it and you get one of the most-quoted lines in video game history: "All we had to do was follow the damn train, CJ!" — Smoke's exasperated rant, a permanent fixture of GTA meme culture.
Here's the factual part people skip: its infamy outruns its actual difficulty. The mission isn't a precision or luck test like "Supply Lines..." — it's a pacing test. Keep the bike level with the train so Smoke has clean shots, take the more direct route rather than chasing the tracks literally, and don't wipe out. It's frustrating on a blind first run and trivial once you know to ride ahead and let Smoke work. It's the most famous hard mission in San Andreas; it is not the hardest.
A handful of missions have a real claim to second place — most of them, tellingly, involve aircraft:
San Andreas has shipped on PS2, Xbox, PC, mobile and the 2021 remaster, and the controls — especially flight and the RC Baron's aiming — differ across them. "Supply Lines..." is hardest on the original PC release's mouse aiming; some later versions are marginally kinder. This piece is about the original game's difficulty, the one the consensus was built on. If you want to actually replay any of this today, the San Andreas multiplayer in 2026 explainer covers what still runs, and the 100% completion checklist shows where these missions sit in the bigger grind.
If you want the defensible, consensus-backed answer: "Supply Lines..." is the hardest mission in GTA San Andreas — twitchy controls, punishing aim, partly luck-based, and on a hidden timer. "Wrong Side of the Tracks" wins the memes and the quotes, but it wins infamy, not difficulty. Everything else is a fight for a distant second.
