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.
Part 3 of 12 in Main story
1. Outside: past the wall and the army patrols. 2. Downtown: across the city and through the Goldstone Building. 3. Museum: a fight through the Freedom Museum of Boston. 4. The Capitol Building: the meeting point and a flooded subway.
You leave through tunnels under an apartment block and climb out beyond the wall, which is Ellie's first time outside. A patrol detains the three of you, Ellie stabs a soldier during the scan, and Joel and Tess kill both soldiers in the scuffle. The scanner shows Ellie is infected, but there is no time to argue: more troops arrive, and you sneak through the trenches and drop into the sewers. Tess's list and a patrol routes map are found here.
Tess sides with Ellie about pushing on, and Joel follows. A chasm forces you into the leaning Goldstone Building, where Tess explains clickers to Ellie and you learn to distract them with thrown objects. A dead army patrol shows what stalkers can do, then a crowd of runners blocks the far end of the building. A subway station beyond holds dead Fireflies, a Molotov and a note. Four artifacts and Lenz's pendant are in this stretch.
A wave of infected chases the group into the museum. A floor gives way and leaves Joel alone with clickers, and you work through the exhibits until you hear Tess and Ellie under attack behind a door. A big fight follows before the three climb to the roof. The medical pamphlet and Kiper's pendant are here.
You reach the State House to find a dead Firefly outside and the rest killed inside by the military. Joel and Tess argue over what to do next while she searches the bodies for directions to the lab. This section holds two artifacts, the Firefly orders and a smuggler note, plus Davidson's and Jiang's pendants. The way out runs through a flooded subway.
Tess reveals she was bitten in the museum fight and that her bite is already worse than Ellie's. She asks Joel to take Ellie to Tommy, who will know where the Firefly lab is, then stays to hold off the soldiers so Joel and Ellie can escape. Once out of the subway, Joel tells Ellie never to bring Tess up again.

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.
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.
Jackson
Jackson is the short closing chapter of the main story: you play as Ellie, walking through the woods with Joel toward Tommy's settlement in Wyoming in the spring of 2034. It has one section, the Epilogue, and one collectible, the comic Singularity.
