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.
Part 12 of 12 in Main story
The Epilogue is the only section. A blocked road forces Joel and Ellie out of the car, and the rest is a walk on foot through the woods to a lookout over the settlement.
As you follow Joel through the trees and over the barbed wire fence, he tells Ellie that she and Sarah would have gotten along, because the two are a lot alike. Detour right past the fence before moving on if you still need the final comic.
Within sight of the settlement, Ellie admits she carries guilt over Riley, Tess and Sam, and asks Joel to swear that what he told her about the hospital is true. He swears it, lying again, and Ellie answers with a quiet okay as the credits roll.
Singularity is issue 14 and the end of the Savage Starlight run Ellie has been collecting since Pittsburgh. Once you are through the fence and among the trees, ignore Joel's path and bear right until a rusted truck comes into view; the comic lies on its driver's seat. The blurb on the back wraps the series up with Daniela safely home and leading the Last Watch, keeping the truth about Captain Ryan to herself.
Any shirt skin you have equipped for Ellie is ignored here. The chapter opens on a cutscene of her looking at her bite, so she stays in her red flannel for the whole walk.
Tommy's Dam
Tommy's Dam brings Joel and Ellie to Jackson County, Wyoming, months after Pittsburgh, where they find Joel's brother Tommy helping run a hydroelectric plant for his wife Maria's settlement. It is a short chapter built around a reunion and two fights with bandits, one at the dam and one at an old ranch house.
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.

Lakeside Resort jumps to winter and puts you in control of Ellie near Silver Lake, Colorado, hunting with a bow and searching for medicine. She runs into two strangers, David and James, and for part of the second half the game switches you back to Joel.
