The Last of Us Part I Chapters: Full Walkthrough Order

The Last of Us is not twelve levels. It is four seasons, and the season you are in tells you more about how an area will play than any chapter name does. Here is the whole road, in order.

Joel and Ellie together in The Last of Us, the two characters you follow across all twelve chapters and four seasons of Part I.

The Last of Us is not twelve levels bolted together. It is four seasons, and once you notice that, the whole game reads differently. Which season you are standing in tells you more about how the next hour will play than any chapter name on the loading screen does. Summer teaches you the systems and buries you in enemies. Fall is a short, brutal comedown. Winter takes the controller out of Joel's hands entirely. Spring closes the loop, fast.

There are twelve chapters in Part I, counting the prologue and the epilogue, and they are grouped under those four seasonal arcs — Summer, Fall, Winter, Spring — each one opening after an unstated gap of weeks or months, with the scenery, the weather, and the relationship between Joel and Ellie all shifted to match. This guide walks the whole road in order, tells you what each stretch actually asks of you as a player, and flags where the difficulty genuinely spikes. It covers the first game only — the original, Remastered, and Part I remake share this exact structure. New to the series? Start at the The Last of Us coverage hub or the wider Mythras blog.

One spoiler note: this names locations, companions, and the season each falls in. It does not spell out the big story beats or the ending — that lives in our ending explained breakdown, and you should not read it until you have finished.

How the game is structured: four seasons, twelve chapters

Here is the entire skeleton on one screen. Memorize the seasons, not the chapter titles, because the seasons are what actually change how you play.

The shape that matters: Summer is six of the twelve chapters. More than half the game is one long, escalating summer, and it is where nearly everything you learn about stealth, crafting, and the infected gets front-loaded. Fall and Winter are single-chapter arcs — short, dense, and each one flips the game on you. Spring is the sprint to the finish.

Prologue: the outbreak-night opening

The prologue is roughly twenty minutes long and it is the best opening in the medium, so play it slowly. You start as Sarah on the night the Cordyceps outbreak breaks containment in 2013, then take over Joel as the three of you try to get out of town. There is almost no combat and no crafting — it is a controlled panic sequence designed to teach you movement and to make you care before the game asks anything of you.

Then it hard-cuts twenty years forward to a Boston quarantine zone, and the real game begins. Do not expect the prologue's pace to continue. It does not.

Summer: Boston to the dam

The Boston quarantine zone at dusk, the ruined skyline where Joel and Ellie's journey begins in Summer.

Summer is the bulk of the game and the stretch where you build every habit you will lean on later. It runs from the Boston quarantine zone all the way out to Tommy's dam in Wyoming, and it is where you meet Ellie, learn to smuggle, and get your first real look at every infected stage. If you want a systems primer before you dig in, our infected guide and weapons guide both map cleanly onto what Summer throws at you.

The Quarantine Zone and The Outskirts

The Quarantine Zone (Chapter 2) eases you in with human patrols, a smuggling job, and your first taste of the QZ's grim politics. The Outskirts (Chapter 3) is where the training wheels come off: your first infected, in the flooded, spore-filled ruins of downtown Boston and a museum. This is where you learn that a clicker is a completely different problem from a runner, and where players who never read the infected up close start dying. Take it slowly and let the area teach you.

Bill's Town

Bill's Town (Chapter 4) hands you a memorable one-off companion and a town rigged wall-to-wall with traps, both his and the infected's. The objective boils down to scavenging a working vehicle, which means a lot of doubling back through infected-heavy streets. It is also a strong crafting-economy lesson — this is where hoarding shivs and molotovs starts paying off. If your resource management feels shaky, our crafting and upgrade guide is the companion piece.

Pittsburgh and The Suburbs

The ruined Pittsburgh skyline, the setting for the game's toughest human ambushes and a notorious bloater fight.

Pittsburgh (Chapter 5) is the difficulty wall of Summer. It swaps the infected for hunters — organized, aggressive human survivors who flank, throw bricks, and do not spook the way infected do. The hotel section contains a basement encounter with a bloater alongside stalkers that catches a lot of first-timers flat. Pittsburgh is also where you meet Henry and Sam, who carry into The Suburbs (Chapter 6), a shorter chapter that mixes sewers full of infected with more hunter combat. If Pittsburgh is grinding you down, our difficulty modes guide explains exactly what each setting changes and whether you should drop down.

Tommy's Dam

Tommy's Dam (Chapter 7) is the exhale at the end of Summer. You reach Tommy's hydroelectric dam settlement in Wyoming, there is a defense sequence, and the chapter is heavier on story and quieter on combat than anything since the prologue. It is also the seam where the game pivots from "survive Boston" to the mission that carries the back half.

Fall: The University

The overgrown campus of the University of Eastern Colorado, the single chapter that makes up the Fall arc.

Fall is one chapter — The University (Chapter 8) — and it is a masterclass in tone. You arrive at the University of Eastern Colorado chasing a lead, the campus is eerily calm, and the game lets that quiet stretch until you are certain something is wrong. It ends with one of the sharpest difficulty and tone spikes in the game: a running fight and a wound that changes who holds the controller. Fall is short. Do not let its calm opening lull you into burning resources you will want the moment it turns.

Winter: Lakeside Resort

Ellie and a recovering Joel in the snow, the Winter arc where you take control of Ellie for the first time.

Winter is the game's boldest structural move. Lakeside Resort (Chapter 9) takes Joel out of your hands and makes you play as Ellie — a smaller, weaker protagonist with a different toolkit and a bow as her signature weapon. You open by hunting a deer in the snow, then run into David and his group of cannibalistic survivors, and the chapter builds to a claustrophobic pursuit and a boss encounter that is as much about nerve as aim.

Mechanically, Winter is a stealth-and-bow chapter. Ellie cannot slug it out the way Joel can, so the whole arc rewards patience, throwables, and picking your moments. It is short, it is tense, and it is the emotional hinge of the game. Many players rank it the best single chapter in the series.

Spring: the Bus Depot, the lab, and the epilogue

Spring closes everything out across three chapters and it moves fast. The Bus Depot (Chapter 10) puts you back in control of Joel, heading for Salt Lake City, and contains the game's famous giraffe moment — a deliberate beat of calm before the finish. The Firefly Lab (Chapter 11) is the destination the entire journey has pointed at, a hospital sequence that is short on puzzles and heavy on consequence. The Epilogue (Chapter 12), set outside Jackson, lands the ending in a handful of quiet minutes.

Spring is not a difficulty gauntlet the way Pittsburgh or the University are — it is a payoff. Save a few resources for the lab and let the story do the work. What actually happens there, and why it splits players so hard, is the subject of our ending explained piece — again, only after you have played it.

How long the whole thing takes

A first playthrough of the main story runs roughly fourteen to sixteen hours if you explore and read optional notes, and closer to twelve if you push straight through. The distribution is lopsided: Summer eats over half your total playtime, while Fall, Winter, and each Spring chapter are far shorter, single-sitting arcs.

If you are hunting collectibles — comics, Firefly pendants, training manuals, artifacts — plan to slow down considerably, especially across the sprawling Summer chapters where the optional areas are largest. Our collectibles guide breaks down where each type clusters so you are not backtracking blind. And if you are eyeing a second run on the hardest setting, the Grounded mode guide is essentially a re-read of this same route with the resource math tightened to the bone.

Quick Action Checklist

  • Think in seasons, not chapters. The season you are in predicts the encounter design better than any level name.
  • Summer is six of twelve chapters and front-loads every system — treat it as the game's real tutorial and build good crafting habits early.
  • Play the prologue slowly. It is short, combat-light, and the best opening in the genre.
  • Expect the difficulty to spike in Pittsburgh (hunters plus a bloater) and at the end of the University chapter.
  • Winter hands you Ellie and a bow. Switch to patient, stealth-first play — she cannot brawl the way Joel does.
  • Spring is a payoff, not a gauntlet. Bank a few molotovs and health kits for the lab.
  • Budget fourteen to sixteen hours for a thorough first run, most of it in Summer.
  • Slowing down for collectibles roughly doubles your time in the big Summer chapters — plan around it.

Frequently Asked Questions

How many chapters are in The Last of Us Part I?
Twelve, counting the prologue and the epilogue. They are grouped under four seasonal arcs: Summer, which spans six chapters from Boston to Tommy's dam; Fall, which is the single University chapter; Winter, which is the single Lakeside Resort chapter; and Spring, which covers the final three chapters.
What order do the chapters go in?
Prologue, The Quarantine Zone, The Outskirts, Bill's Town, Pittsburgh, The Suburbs, Tommy's Dam, The University, Lakeside Resort, Bus Depot, The Firefly Lab, and the Epilogue. The first seven fall under Summer, the University is Fall, Lakeside Resort is Winter, and the last three are Spring.
Which chapter do you play as Ellie?
You control Ellie for the whole Winter arc, the Lakeside Resort chapter. It is the only main-story stretch where Joel is not the playable character, and it swaps in Ellie's bow-focused, stealth-heavy toolkit. You also briefly play as Sarah at the very start of the prologue.
How long does The Last of Us take to beat?
A thorough first playthrough runs about fourteen to sixteen hours, and closer to twelve if you rush the main path. Summer accounts for more than half of that, since it is six of the twelve chapters. Hunting collectibles adds significant time, mostly in the larger Summer areas.
What is the hardest chapter in the game?
Pittsburgh is usually the toughest for a first-timer, because it trades the infected for organized human hunters and features a basement bloater-and-stalker fight. The end of the University chapter and the David encounter in Winter are the other big spikes. Our difficulty modes guide covers what each setting changes.
Is Left Behind part of the main chapter order?
No. Left Behind is a separate DLC campaign, not one of the twelve main chapters, and it is played as Ellie in two interwoven timelines. This walkthrough covers only the main story of Part I. Left Behind can be played on its own from the main menu.
