GTA: San Andreas is full of legends, and it's got me chasing ghost ships and urban myths like a schoolkid in 2004

In a first-floor flat above San Fierro's Chinatown, the amiable Triad leader Woozie is on the couch, clutching a gamepad. He's busy thrashing CJ Johnson in competitive multiplayer, much to the consternation of our protagonist. "How are you in the water?" Woozie asks, changing the subject. "Can you swim well?"

"No," replies CJ. "I can't." The cutscene is a reflection of the background stat tracking that goes on in GTA: San Andreas—recording the player's weapon skill, driving ability, stamina, muscle, fat, and most pertinently, lung capacity. This moment in particular is notorious among GTA fans, since it demands you raise your underwater swimming skill to 20% before proceeding to the next mission—an oceanic infiltration of a cargo ship which must be completed to see the rest of the game.
