The Quarantine Zone starts the story proper 20 years after the outbreak, inside Boston's military-run zone in August 2033. As Joel, now a smuggler, you and his partner Tess slip outside the wall to track down Robert, a dealer who owes them guns, and end up taking a new job from the Fireflies.
Part 2 of 12 in Main story
1. 20 Years Later: a walk through the zone with Tess. 2. Beyond the Wall: a detour through ruined buildings outside the wall. 3. The Slums: the black market and the warehouses on the waterfront. 4. The Cargo: the end of the chase for Robert and the meeting with Marlene.
Tess wakes Joel to say Robert's crew jumped her. On the walk to the checkpoint you see a ration line forming before it opens and soldiers in hazmat suits scanning people pulled from a condemned building, with deadly results for anyone who tests positive. A Firefly bomb then wrecks an army vehicle at the checkpoint, the soldiers clear the streets, and Joel and Tess head for the tunnels instead.
Your first time outside the zone doubles as a tutorial for sneaking and fighting runners. In one building the air is thick with spores, so gas masks go on; a group trying to break into the zone has been overrun there, and a survivor pinned under rubble with a torn mask asks Joel to finish him. That choice is yours. This section holds three artifacts and two pendants.
Joel and Tess bribe their way into the slums, passing market stalls and a fistfight where onlookers bet ration cards, and a guard backs down once he recognizes Tess. Another guard says Robert went to the wharf, so you fight his men through a run of warehouses at Mission Hill Pier. Five artifacts sit in this section, including a wanted poster, a drafting notice and a warehouse key.
A short chase corners Robert, who admits he passed their guns to the Fireflies to settle another debt. Marlene, wounded from a clash with soldiers, offers the guns back with interest if they smuggle something to the capitol building. After slipping past more patrols she shows them the package: Ellie. Liu's pendant is in this last section.
Once Robert has talked, Tess shoots him. Joel only agrees to Marlene's job after she shows Tess the weapons, and the three set out that night.
The Outskirts
The Outskirts takes Joel, Tess and Ellie out of the Boston quarantine zone and across the ruined city toward the capitol building, where Fireflies are meant to collect Ellie. It is where you meet clickers and learn to slip past them with thrown bricks and bottles, on a route through downtown, the Goldstone Building and a history museum.
The Firefly Lab
The Firefly Lab is the second-to-last chapter, set inside Saint Mary's Hospital in Salt Lake City, where the Fireflies have their base. It is a single section played as Joel, and its five collectibles include the recordings that explain what the Fireflies have learned from Ellie.
Bill's Town
Bill's Town brings Joel and Ellie to Lincoln, Massachusetts, a small town that Joel's paranoid contact Bill has rigged with traps to keep the infected out. Bill owes Joel a favor, so you team up with him to find a working car, which means a trip through a clicker-filled graveyard and an infected high school.

Bus Depot opens in the spring of 2034 as Joel and Ellie walk into Salt Lake City, aiming for the Fireflies at Saint Mary's Hospital. The route runs along a highway full of dead cars, through the Logan James bus station and an abandoned quarantine zone, and down into a flooded tunnel full of infected.
