In Polygon’s The Last of Us “Pittsburgh” collectibles guide, we’ll show you the location of the 17 artifacts, 3 Firefly pendants, 4 Training Manual, 4 comics, and 1 tool.
“Pittsburgh” has four sections: Alone and Forsaken, Hotel Lobby, Financial District, and Escape the City, but you won’t see those names as you’re playing the game. You can find, select, and begin playing at any section from the Chapters option on the main menu. We’ll explain where and when each part begins and ends at the top of each section below.
Alone and Forsaken collectibles
Alone and Forsaken starts with the shootout in Pittsburgh, and continues through a couple more fights with hunters, a huge bookstore, and a flooded street. This section ends once you reach the hotel.
Siphon Hose artifact location and Force Carrier comic location
You’ll get the Siphon Hose artifact and the Force Carrier comic from Bill during the cutscene between chapters.
Tools level 2 location
After the shooting stops, loot the convenience shop and the mechanic across the street. You and Ellie will duck into a grisly garage. The tools level 2 is in a toolbox to your left.
Tourists Manifest artifact location
Inside that same gnarly garage, the Tourists Manifest is on a knocked over rack blocking the door along the right wall.
Health: Splinting Training Manual location
Take the stairs up from the garage, and head into the first door on your right. The Health: Splinting Training Manual is on the shelves on your left.
Ambush Map artifact location
Head through the door at the end of the hall outside the sleeping quarters. The Ambush Map is on the wall to your right (and there’s a workbench in here, too).
Termination Shock comic location
When you head outside, you’ll drop down onto a street. There’s a crashed bus off to your right. Climb onto the bus through the open door, and turn left. The Termination Shock comic will be on the floor.
Lost Hill Note artifact location
At the far end of that street, you’ll meet three more bad guys. After the fight, climb over the bus into the military checkpoint. Drop down, and climb over the sandbags on the right side. The Lost Hill Note is inside the guard booth.
Kazden Risk Firefly pendant location
Through the checkpoint, you’ll run into a lot of hunters. The fight will take you from the checkpoint into a huge bookstore on the right. The next five artifacts are all in this area. Once all the hunters are dealt with, head back into the main square. Face the bookstore, and make your way toward the gate along the left. There’s an alley that runs along the left side of the bookstore (there’re metal stairs up to the second floor here). The Kazden Risk Firefly pendant is at the back of the alley behind some shelves.
Traitors Flyer artifact location
Back in the main square, head to the front doors of the bookstore (they’re most of the way back toward the gate you came through, under a big green sign).
Facing the front doors, turn right. The Traitors Flyer is on a metal barricade wall.
Applicant Checklist artifact location
Walk through the front doors of the bookstore, and turn right. The Applicant Checklist is under the stairs in the corner.
Abandon Zone Note artifact location
From that staircase in the front right corner of the bookshop, continue along the right wall on the first floor. Straight back (past the Biographies sign on the ceiling), climb through the window into what looks like a break room. The Abandon Zone Note will be on your left.
Lost Areas Map artifact location
Head up to the second floor of the bookstore (there are stairs in the back right corner). Look for the cafe (also in the back right corner). Unlock the shiv door to the right of the counter. The Lost Areas Map and some supplies are inside.
Mother’s Letter artifact location
After you leave the bookstore, you’ll walk through some alleys until you spot a couple hunters moving a plank. From where you hide behind a taxi, look to your left. Open the shiv door marked with a red X. You’ll find the Mother’s Letter inside, along with a bunch of supplies.
Stash Note artifact location
Back on the street, head for the flooded area. There’s a box truck crashed into a(nother?) River Cafe along the left side. Swim through the truck into the cafe. Swim to the stairs at the back to climb up to the second floor. The Stash Note is on the far side off the floor on a wooden counter (next to a shiv).
Hotel Lobby collectibles
The Hotel Lobby section, unsurprisingly, starts as you enter the hotel lobby, and ends after Joel and Ellie escape the hotel.
Note to Staff artifact location and Shiv: Reinforcement Training Manual location
Inside the hotel lobby, you’ll use a ladder to climb up to the second floor (in the back left corner). At the top of the ladder, turn right, and shuffle across to the far side. The Note to Staff is in a suitcase by the elevators.
The safe code written on it is for the safe near the front desk. From where you picked it up, face the front of the hotel. The front desk is on the left in the front corner. Head behind the counter and into the attached room. The safe will be on your left. You’ll find the Shiv: Reinforcement Training Manual inside.
Hotel Keycard artifact location
A whole lot of hotel room looting and hunter strangling later, you’ll need to find your way through a flooded and spore-filled basement, and then power up a generator. You’ll need this artifact to progress, so you can’t miss it. You’re looking for a security room with a bank of monitors at the top of one of the collapsed sections of floor. The Hotel Keycard is on the desk.
Accretion comic location
Once the lights are on, you’ll use the Hotel Keycard to head back upstairs. After you take out the hunters in the kitchen and dining room, you’ll reunite with Ellie. Use the ladder to climb up to the second floor (again), and then take two lefts to reach the second floor of the dining room. Shuffle across to the bar side, and the Accretion comic is by the couches on your left.
Colby Reed Firefly pendant location
Back with Ellie, drop down to the first floor. Head into the second door on the left — the women’s bathroom. The Colby Reed Firefly pendant is in the stall on the left along the opposite wall.
Melee: Knots Training Manual location
In the main hall, continue just a little past the lobby, and the Melee: Knots Training Manual will be on a desk along the left side.
Financial District collectibles
The Financial District begins after Joel and Ellie escape the hotel, and launch their assault on the hunter-filled square. It wraps up when Henry and Sam lead you to their hideout.
Fireflies Note artifact location
The square where you start this section is full of hunters. Take them all out, and worry about the collectible after.
From where you started this encounter, head straight across the square. There’s a sub shop in the far right corner (after yet another Rivers Cafe). Inside, head behind the counter and into the room beyond. Turn around to your left to find the walk-in freezer. The Fireflies Note is on the ground inside.
This is the only collectible in this square, so once you’ve grabbed it, spend some time collecting supplies before making your way to the makeshift barricade.
Final Attack Note artifact location
You’ll leave that square through a garage (with a workbench). As you leave, you’ll see a cutscene, and then head up some stairs. At the top, you’ll encounter a couple more hunters. Once they’re dealt with or avoided, head into the long human resources (there’s a sign next to the door) office to the left of the stairwell. The Final Attack Note is under a desk at the far end.
Mob Attack Note artifact location
Back down at street level, you’ll eventually spot some hunters in a building to your left. On the second floor of that building, in the section missing walls and windows, look for a room in the back by the stairwell. The Mob Attack Note is under the large, L-shaped desk.
Truck Note artifact location
Back downstairs, take a right and handle a few more hunters. At the end of the street along the right side, you’ll spot a credit union that’s been converted into a ration depot. The Truck Note is on a counter inside.
Molotov: Construction Training Manual location
From the ration depot, head up the fire escape (to the left of the “Death for Freedom” graffiti), and down onto a new section of streets and alleys. After that, there will be a long (and stressful) sequence where you have to evade a truck-mounted machine gun. Keep pushing on until you meet Henry and Sam in a cutscene.
After the cutscene, follow them out of the bedroom. The Molotov: Construction Training Manual is on the counter in the apartment’s kitchen.
Deep Phase comic location
From Henry and Sam’s apartment, follow Henry and Sam to the next floor down. At the bottom of that first flight of stairs, you’ll find a shiv door. The Deep Phase comic is inside that apartment in the kid’s room on your left as you enter.
Lucas Rios Firefly pendant location
Follow Henry through the toy store and up onto the roofs. After handling a couple more hunters, you’ll head inside another building. Henry will unlock a door on the right side of the hallway. Before you follow him, head into the bathroom on the left side of the hall. The Lucas Rios Firefly pendant is in a stall on the left side.
Trial Note artifact location
Cross the hall into the room that Henry unlocked. Straight back from the door, there’s a conference room attached to this office. The Trial Note artifact is on the ground in the righthand corner.
Escape the City collectibles
The final section of the chapter starts with Henry and Joel staging their nighttime raid on the military checkpoint and closes out this chapter.
There are no collectibles in Escape the City.
