In Chapter Order 100% Achievement Walkthrough Guide: The Last of Us Part 1

This is a walkthrough guide to get 100% of all the achievements within a single playthrough, in chapter order, for The Last of Us Part 1.

Intro:

Hello and welcome to my 100% walk-through guide on how to get each achievement in Chapter order. In this guide, I will go step-by-by in order of what collectables to grab and where they are to 100% of the game in a single play through. This guide is for new players that want all the achievements or a returning player like me that just wants to quickly 100% the game.

I have also made an Last Of Us Part 2 guide, if you are interested.

Disclaimer:

This guide is a work in process, and parts were made before the game was out, so all the imagines on collectables I took from PS5Trophies' video on The Last of Us Part 1 Collectables Guide, and IGN website.

The Last of Us Part 1 base game has 225 collectibles and 21 related achievements, all of which can be done in a single playthrough. It'll take us around 21½ hours to get everything done in the base game.

There are no achievement/s linked to difficulty in the remake, so you can play it on the easiest difficulty if you want to make the ride a little smoother. That being said, I would recommend playing on a difficulty lower than 'Grounded'. As in my playthrough, I missed some achievements and a Shiv door because the game didn't be enough resources. So, be warned, if you play on a higher difficulty, you may miss a collectible and have to reload a chapter in the main menu.
Before we begin, we should have some just general tips:

Firstly
• This game has some great accessibility settings; we can use this to help find the collectibles and supplies more easily. Just go into settings and then accessibility. Once there, turn on high contrast mode. This will allow us while in-game to turn contrast mode on, basically turning anything non-intractable gray, but everything else in color. So, it will highlight collectables like Pendants to find more easily, like when in a tree.
  
  Secondly
  
• Try not to use your Shivs: There are a lot of Shav doors, more so in the Pittsburgh area. So it's best to keep them healthy for those doors or keep the blades to upgrade 5 different melee weapons we need for the "Build em up, Break em down" achievement (I'll talk about at in the Hotel Lobby chapter).
  
  Thirdly
  
• Throughout the game, we will collect parts. There is an achievement called "Combat ready" that requires us to upgrade a weapon fully. The easiest one to complete is the Revolver, but it's up to you one gun you want to upgrade fully. The lower the difficulty, however, the more parts. So, play however you like, but you should be able to get the achievement even on the hardest difficulty.
  
  Lastly
  
• For the "Geared up" achievement we need to craft all 6 items: a Health kit, a Molotov, a shiv, a nail bomb, a smoke bomb, and a melee upgrade. So, even if you are like me and don't use the smoke bomb at all. At some point, you'll have to craft one of each in the game.

Disclaimer

This chapter has no achievements or collectibles; it's only for the story. There are items you can pick up and look at as Sarah, but none of these items count towards the Chronicles achievement. So, you are free to speedrun this part if you want.

Right before the checkpoint on the left, walk to the right and wait for a guy to walk over to a woman instead. When zJoel is near, they will talk, and then ask Joel a question

Beyond the Wall

Artifact: 1-2/8 After running from the Firefly attack and shimming through the hole behind a shelf: we'll walk through a tunnel, and at some point, you'll have to pick up Joel's gear. You automatically get 2 Artifacts.

Firefly Pendant: 1/3 David Vigil After leaving the Cafe shop, you have to find a ladder to climb into the side of a building. After climbing up, you have to turn right into another room. Head into the bedroom that is straight ahead, and a Pendant should be on the left-hand side of the bed. Once we pick this Pendant up, we will also get the "Fallen firefly" achievement.

Fallen firefly

Collect 1 Firefly pendant.

Optional Conversation 3/4 Source of the Spores When you are forced to put on a mask because of spores, you will have to couch walk through a bit of the building. You will see a dead clicker/runner up against a wall at some point, and a prompt will come up. Hard to miss.
Artifact: 3/8 Note to Brother After fighting your first runners, head upstairs, and instead of walking forward to go outside, turn left and head for the door in front of you. It should be a note on a table on the left-hand side.
Firefly Pendant: 2/3 Ben Glueck After you have to put down a plank to cross a gap and you jump out of the building. You'll run outside with Tess and eventually have to couch underneath a fallen fire escape into an open area. There is a tree to the left, head over to the tree, and there will be a Pendant hanging on the tree on the left.

The Slums

Artifact: 4/8 Drafting Notice After a while, you'll come to a different area within the QZ with people in it. Walk by a market area and walk to the other end of the bus. After a short cutscene, exit the bus, walk forward, and on the ground to the left, in the middle of a lot of other papers, will be an Artifact.
Artifact: 5/8 Wanted Poster From the last Artifact, head forward towards the notice board, and pick up the poster.
Artifact: 6/8 Warehouse Key A while ahead, you'll reach a room with 2 people in it; whatever one the player kills, they will drop the keys. This key counts as an Artifact, and you'll need the keys to continue anyways. You can't miss it.
Artifact: 7/8 Shipping Manifest After a cutscene at the docks, you enter a battle area. The first Artifact here is basically straight ahead of us, to the right of where the player first drops down. It's along the side near 2 buckets in front of a big blue tub.
Artifact: 8/8 Docks Note The other Artifact in this area is close. Just walk forward, then take a right. It will be in the left corner behind 2 blue tubs and in front of the big rusted ship.

The Cargo

Optional Conversation: 4/4 Body Pile After some time with Marelene, you'll walk into an open area with some QZ guards. You have to deal with them all to get the Optional Conversation in this area. When they are all dealt with, cross the bridge to the right and head to the pile of bodies. Wait for Marelene to head over and for the prompt to appear.
Firefly Pendant: 3/3 Philip Liu The last collectible for this chapter is a Pendant. After the cutscene ends after meeting Eille, walk straight towards a body up against a newspaper dispenser, which the Pendant should be on the right of the body.

Outside

Artifact: 1 Tess' List As soon as the cutscene ends of Joel waking up at night, do the classic gaming trope of turning around and heading back inside the room he was in before. It's on the side table with the lamb on it.
Optional Conversation: 1 Marlene Either pick up the note first or not: head over to Tess standing near the window and a prompt should appear.
Artifact: 2 Patrol Routes Map After turning on the generator and going down the elevator. Look to the right and a note should be there.

Downtown

Artifact: 3/9 Evacuation Leaflet A long time later, after fighting and running from the QZ guard. At some point you will climb up onto a street that is just beneath some skyscrapers. On the right-hand side you'll find between a trash can and a car a note.
Firefly Pendant 1/4 Lenz After some walking, you'll come acorss the entrance to a skyscraper. Walk right and all the way down the end to the first tree. The Pendant will be on the tree, on the right-hand side. If too hard, turn on high-contrast in the accessibility options.
Optional Conversation: 2/4 Dead Soldier in The Goldstone Building When done, head into the skyscraper and through the doorway. A dead body should be to the right, right before the next doorway. A prompt will show up and you'll start an optional Conversation.
Artifact: 4/9 Field Ops Log Head up the stairs and after the first set, you'll find a body against the wall. A note will be next to him.
Shiv Door: 1/2 Head up the stairs and at some point, a cutsense will happen with a clicker. When the cutscene is over, head into the room to the right, then take a left to the next room. The door now in front of us needs a Shiv. Use an unused Shiv to get in.
Arifact: 5/9 Firefly Map Sometime later, you'll head underground into the subway underneath the skyscraper. Walk forward, and you'll can pick up a Molotov to the left here. Past that, keep walking forward up the blocked-off stairs, and a note will be next to a body on the right.
Artifact: 6/9 Note to Derek The next room will be an infected battle room, with many clickers, a handful of runners, and 1 Artifact and 1 Safe. Head left as we enter the room, and there should be a runner eating a body in front of the shop we want to go into. Head into the shop, walk behind the cashier and open the drawer to get a note with the Safe code on it.
Safe: 1/1 03-43-78 Now, the Safe is on the other end of the room from where we are now, so head on over to the bookshop. There will be a runner inside this shop, but he is basically sleeping, making it easy to walk up on and stealth kill. Head on over behind the counter of the shop, and the Safe should be there.

The Museum

Artifact: 7/9 Medical Pamphlet Once out of the subway and on the streets again, there will be a truck in the way that you'll have to climb over with a box. Jump over to the other side, but then turn around to head inside the truck. Inside the back of it will be a note.
Workbenches: 1/1 Right after running into the building and after the cutscene, to the back left of the room, to the left of the doorway to get out of this room, will be our first workbench of the game. We need to interact with it to make it count towards the "Prepared for the Worst" achievement.

Disclaimer:

As stated at the beginning of the guide, there is an achievement called "Combat ready", where we must fully upgrade at least one weapon. You should be able to easily get this achievement just by playing the game if you're always looking around for supplies and parts from room to room. The Revolver will be the quickest gun to upgrade, only costing 155 parts and needing level 3 Tools. We also need to look out for Toolboxes to allow us to get better upgrades for our weapons, starting in the next chapter.

Firefly Pendant: 2/4 Kiper Walking a few steps forward, we head into a room that has had the floor above collapse. We need to walk up this ramp, hugging the left of it, and once up the top of the ramp, turn around and while hugging on the right still, shimmy across the small path to the other side to get a Pendant that's within a display case.
Shiv: 1/2 After being separated from Tess and Ellie, turn around, take the first door on the left, go past the double doors, and then take the door on the left. To our right, after entering, will be another Shiv door.
Optional Conversation 3/4 Checking up on Tess After meeting up with Tess and Ellie and clearing the room of infected, head over to the open windows on the left side of the room. Don't climb the window or be too close to Tess Wait for them to walk up to the window to get 2 Optional Conversations. First Optional Conversation is with Tess. The Prompt should show up when she's leaning out of the window. Save encase Tess climbs the window.
Optional Conversation 4/4 Checking up on Ellie The second Optional Conversation will be with Ellie. Right after talking with Tess, the prompt should show soon after.

The Capitol Building

Artifact: 8/9 Firefly Orders Right after the cutscenes and timeskip, we head down a flight of stairs. Right at the bottom of these stairs, turn around to the right and walk towards a dead body to find a note near it.
Firefly Pendant: 3/4 Davidson After moving the dumper and then climbing over it to get back onto the street, we'll head into a big area that is fully flooded. We want to follow the road forward and instead of turning right into the capitol building, we want to turn left towards the gazebo. Inside will be a Firefly Pendant on the floor, in the water; it's a little hard to see.

Hunting Rifle
When in the capital will be a lot of fighting, so be ready. Head deeper inside after jumping over a small gap. There will be the rifle we can pick up near a dead body; it's hard to miss.

Artifact: 9/9 Smuggler Note Right after leaving the capital and entering the flooded subway, at some point, you and Ellie will come to a part of the subway that Ellie can't cross. So you have to find the wooden pellet to help her cross. Instead, go to the left-hand side where Ellie is standing and waiting. There should be a dead body leaning up against the wall. There should be a note next to him.

Firefly Pendant: 4/4 Jirang While next to the body, where the last Artifact was, will be some flooded stairs to our left; we need to swim down them. Swim down and go straight through. At some point you'll see a doorway to the left; head into that room. In this room will be some parts and a Firefly Pendant on a shelf.

The Woods

We are now in Bill's town, a fun area with a bit of collectibles that are mostly in the same spot.

After walking through the forest to the town gate, we will find a pipe with blades on it while looking around. I do not believe this counts towards the "Build Em Up, Break Em Down" achievement, but I could be wrong. Anyways, the pipe is hard to miss as its right on top of the roof we need to walk on to get past the fence.

Actifact: 1/11 Pills Note After walking into the town, we will drop down into a somewhat open area that has a shed and building in front of us. Enter the building in front of us and enter the first room on the left. On the other end of the room will be the first note of this chapter.
Shiv Doors: 1/2 There is some loot in this area, so be sure to look inside and outside the building. Be warned, as there is a sleeping clicker inside the shed, so be sure to deal with it carefully. Once finished looting around, we can now drop down on the left side of the building, and right after dropping, turn left to see the first Shiv Door
Optional Conversation 1/5 The Turning After going though the locked gate. This area is open and has a lot of loot, so you could go around and loot or walk towards the two-story building straight ahead when we enter the area and go to the first floor of the pizza shop. Inside we will find an arcade machine called "The Turning", stand next to it, and wait for Ellie to walk up to it. The Prompt should then show.
Artifact: 2/11 Note to Bob Afterward, head down the street to the wooden blockage that is blocking us from the church. A note with the combination to the Safe in this area will be stuck in some wire at the blockage.
Firefly Pendant: 1/3 Wang Pick up the note, then turn around. There will be an RV in front of us. Climb on top of the roof where a Firefly Pendant will be.
Safe: 1/1 5-17-21 Once done, drop down from the RV and keep walking back up the street until we walk to the eviction notice sign. When at the notice, walk to the alleyway to our left, and at the back end of the truck will be the only Safe in this chapter.
Artifact: 3/11 Perimeter Note After that, walk into the record shop that should be to the left of the wooden blockage that we were at before. Once inside, walk into the back and then take a left for another note.
Shiv Door: 2/2 With that, we are now done with this area, so make sure you loot around before moving on. We will now walk down the alleyway to the left of the record shop. After the clicker blows up, turn right at the red barrel on the right and use a Shiv to open the door.

Keep walking down the alley, and at some point, we will find a body with some arrows on it; pick them up. Then we need to climb up on a truck, but on top of the truck will be the bow.

Artifact: 4/11
Rachel's Note
After getting past the clicker, dropping down to the alleyway, and past the wire, turn left. There will be a door will be at the end of this alleyway. Go up the stairs, head into the room to the left, and take a hard right to a table with "Rachel" written on the wall above it.Warning, a runner will spawn once in this room.

Safehouse

Artifact: 5/11 Bill's Map After the cutscene with Bill is over, turn around and on the table to the left will be a map of the town that Bill was using before in the cutscene; pick it up.
Artifact: 6/11 Fences Note Now, head into the room that's behind us or to the right. A note will be on the coffee table.
Optional Conversation: 2/5 Chess When you're done, you can walk towards Bill and on the left will be a chess board, near the middle of the room. A prompt will appear where Joel talks about chess with Ellie.
Training Manual: 1/1 Shiv Sharpening After that, behind us on top of the bar will be our first Training Manual for Shivs, as well as the "Self-help" achievement for doing so.

Self-help
Find one training manual
Collect 1 training manual.

Artifact: 7/11 Hunters Note With that, all the collectibles are in the bar area, so loot whatever is left or follow Bill. After climbing up the stairs, go right, and on the table in the room will be a note.
Firefly Pendant: 2/3 Vincent Follow Bill for a bit until we walk into an open area, and yes, it's a battle area with infected. Fight them off or run around and make Bill do all the work to save ammo. After clearing the area out, we want to walk between the ambulance and the blue van and look up. A Firefly Pendant should be hanging from the light post. Use a brick/bottle or shoot it down.

Graveyard

Once the cutscene is over, we have a shotgun, and walking to Bill we'll get the nail bomb. This area has a few things we need to get here, so look around.

Toolbox: 1/1
Level 1 Tools
But our first collectible will be the first Toolbox of the game. After picking up the nail bomb, just walk straight forward; it should be hiding in the corner of the room on the left. Just walk up to the red toolbox and interact with it to allow us to get higher upgrades.

Note:

Toolboxes in the game will spawn at different points if you miss one. If you miss this box, the game will spawn one before reaching high school. So you will have a second chance to pick them up, but I'm only going to show where you can pick them up the first time.

Workbench: 1/1 Once picked up, turn right, and there will be the only workbench of the chapter up against the wall. Interact with it for it to count.
Artifact: 8/11 Bomb Note After looting the bottom floor, head upstairs with Bill and walk through the church. But before leaving the Church, there will be a side room on the right, head into the room, and on a table to the left will be another note.
Firefly Pendant: 3/3 Mrozik Now leave the church and fight through the graveyard to the school. There are a few clickers, so watch out. The next area will have a house we can walk into on the right, which is what we want. Find the house and enter it, and on the first floor of the house, in the bathroom, will be a Firefly Pendant next to the toilet.
Artifact: 9/11 Boy's Diary After fighting the infected and looting around, at some point we will need to cross into a tree house and enter a house before the school. Make sure to look around the house first, as this is a no-return point. Go upstairs of the house and enter the kid's room to the right. On the shelf will be a diary.
Optional Conversation: 3/5 Tess We now want to wait for Ellie to come upstairs into the room to start an optional Conversation with Joel about Tess. Just wait here for a bit and then the prompt will show once she is in the room.

High School Escape

Once in the school, we have to fight our way through some infected to get to the gym area, so look around before heading to the gym. Once in the gym we have to fight a wave of runners and then our first bloater of the game. They are weak to fire, so throw some molotovs at them.

Optional Conversation: 4/5 Elile driving After dealing with the bloater, we get a hand from Bill and have to run. We climb a ladder and run into a house for a cutscene to play. After the cutscene, walk to the truck and wait by Ellie. Once Bill has finished talking, you'll get a prompt to talk to her.
Artifact: 10/11 Note From Frank When finished, head deep into the house and look around for supplies while here. But we want to head for the bedroom that is on the far end, and on the left on a table will be a note from Frank.
Optional Conversation: 5/5 Bill reads Frank's note Once that is picked up, we can now give Bill Frank's note we just picked up for a funny Optional Conversation.
Artifact: 11/1 1 Note From Frank (Crumpled) To add insult to injury, we can pick back up the now crumpled "Note From Frank" that Bill just threw away. We have to pick this up as it counts towards the Artifacts counter and also we get the In Memorium achievement for doing so, making this a funny achievement.

In Memorium
Pick up Frank's note after it's discarded
Hand Bill Frank's note and pick it up again after he throws it away.

After this, head behind the truck and push it out. We have to fight some infected while pushing the truck. There is some loot here, but it's little. After pushing the truck and starting it, a cutscene will play us out.

Alone and Forsaken

Artifact 1/17 Siphon Hose At the beginning of this chapter, we automatically get our first Artifact.
Artifact: 2/17 Tourists Manifest After the hunters are dealt with, look around for loot. There is a shutter we need to open to continue, so it's a point of no return. Once we go through the shutter, turn right, and at the far end of the room will find a note on a countertop.
Optional Conversation: 1/14 Prey Once that is picked up, Ellie would have moved to the table with a dead body on it, and a prompt should show up to talk to her about it.
Toolbox: 1/1 Level 2 When done talking, to the left should be the second Toolbox for level 2.
Training Manual: 1/4 Health Splinting Then just to the right of that will be a smoke bomb that we can pick up. Once finished looting the ground floor, head upstairs and go to the room. On a bed on the left will be our second Training Manual.

Workbenches: 1/3 The Workbench will be straight ahead.
Comic: 1/3 Termination Shock At some point, we will leave the building and jump onto the highway below. Once on the road, a bus should be on the right-hand side a bit up. Our first comic will be at the back of the bus inside. Since this is our first Comic pickup, we'll receive the "Savage Starlight Fan" achievement.

Optional Conversation: 2/14 The Military's Doing Now on the other side of the bus is a brown car. Stand next to the car and waiting for Ellie to come. She will say something, and then a prompt will appear.
Optional Conversation 3/14 Jokes: 1/4 Continue up the road a group of hunters will show up on patrol. You can either wait for them to walk by long enough away or kill them; either way, we need to stay next to the bus and wait in this area long enough for Ellie to pull out a Joke book. After saying a Joke, a prompt will appear above her to question her on the book. This is 1/6 Jokes we need to hear for the "That’s all I got' achievement.
Artifact: 4/17 Lost Hill Note When done, climb up on the bus and head toward the little guard hut on the right, get behind the counter, and a notebook will be on the floor.
Optional Conversation: 4/17 Rations Ellie will walk up to some writing on the wall next to the guard hut. Walk up to her, and after saying something, a prompt will appear.

Disclaimer:

Once past the gate, the area ahead has a lot of hunters in it. We have to kill everyone in the area for a Joke/Optional Conversation to appear.

Artifact: 5/17 Traitors Flyer Our first collectible in this area is close by where we entered. Walk forward and the poster will be on the wall between the 2 split paths to the open area, on the other side.
Firefly Pendant: 1/3 Risk The next one is all the way on the other side of the courtyard. There is an alleyway to the left of the library, so walk to the left of the bookstore, walk down the alley, and by the bin at the end will be a Firefly Pendant.
Artifact 6/17 Abandon Zone Note Next, head into the bookstore and go to the stuff rooms that are in the far back right of the building. A note will be in the kitchen room next to the coffee machine on the right.
Artifact: 7/17 Applicant Checklist Now the next note is found beneath the stairs on your right when entering into the bookstore. If you look below the stairs, you'll find the note on a shelf.
Shiv Doors: 1/4 We are now done with the first floor, so it's time to head upstairs. Go up the stairs, and on the far right-hand side will be a locked toilet room, which a Shiv can open.
Optional Conversation: 5/14 and Jokes: 2/4 Now we need to wait for Ellie to tell another Joke. The wait time only counts down once the area is clear, so you may get this prompt earlier or later. Just wait and listen until she starts telling a joke for a prompt to appear. This counts as both a Joke and an Optional Conversation.
Optional Conversation: 6/17 For Looks Once finished in the bookstore, head upstairs and continue forward. We'll reach an open area where a cutscene plays, were some hunters cross over a plank onto a bus. When the cutscene is over, turn around and go to the right, to a store with a poster of a model in the window. Wait for Ellie to look at the poster and then a prompt will appear.
Optional Conversation: 7/14 and Jokes: 3/4 And now we have to wait again for another Ellie joke. Look around in this back area while waiting for Ellie. After a while, Ellie will finally pull out the joke book and a prompt will appear.
Shiv Doors: 2/4 and Artifact: 9/17 Mother's Note Once the Jokes are over, walk forward to a yellow taxi thats next to a cop car. Turn left here and under a blue cloth roof is a door with a red "X" on it. We can use a Shiv to unlock it. Once unlocked, just walk forward and on a yellow chair is a note.
Artifact: 10/17 Stash Note We'll need to enter a coffee shop through the back of a truck. Head into the shop and go to the first floor of the shop. Once there, follow the path around, and on the bench to the right will be a note about the Shiv Door.

Hotel Lobby

Optional Conversation: 8/14 Miss Coffee Now that we are in the Hotel Lobby, turn to the left, and there will be a coffee machine behind a counter. A prompt will appear when near it.
Safe: 1/1 and Training Manual: 2/4 22-10-56 and Shiv Reinforcement Once done, head back to the entrance and go behind the counter on the right for a Safe. Within the Safe will be a Training Manual, so make sure to grab it.
Optional Conversation: 9/14 and Jokes: 4/4 Now that we are done with the ground floor, could you look around for the ladder to continue forward or look for supplies. Once we climb up the ladder next to some elevators,stand next to the elevators for a bit for Ellie to pull out the Joke book one last time. Once the book is out a prompt will appear.
Artifact: 11/17 Note to Staff Right, now we got to cross to the other side of the Hotel Lobby. So walk forward and hug the wall to the left where the stairs used to be to shimmy across. On the other side is a note with the combination for the Safe on it.

Now we are done with the Lobby, so let's continue. At some point, you will climb up some stairs to an open rooftop where a lot of hunters will be. It turns out that this encounter is great for the "Build em up, Break em down" achievement if you haven't been upgraded and getting kills with the 5 different melee weapons.

Here is a video from BushidoCypher explaining it:
https://www.youtube.com/watch?v=QzC-xDZ7Cmg&ab_channel=BushidoCypher

In the video, it turns out you can find the 2x4, the Metal Pipe, and the Baseball bat in this encounter. The 2x4 and Metal Pipe are being carried by 2 hunters while the bat is on a table upstairs. There is a bedroom that spawns the stuff needed to upgrade the weapons. So, head over to that bedroom, craft the upgraded weapon, get a kill with it so the upgrade is broken, and reload the last checkpoint. Once done, we will have to wait until "Tommy's Dam" chapter to get the last 2 melee weapons for the achievement.

Disclaimer:

We must clear both floors for an Operational Conversation to happen.

Optioanl Coversation: 10/14 The Easy Way With that out of the way, head upstairs. Once up top, there is a room with a hole we could of used to climb up. Next to this hole is a bathroom, and to the left is a bathtub with 2 corpses in it. Ellie walks over to the tub and talks with a Prompt above her.
Artifact: 12/17 Hotel Keycard Once that is done and you are finished looking around for supplies, we will have to open an elevator up which is a no-return point. Once open and the cutscene plays of us falling down, We will enter a room with a generator that we have to turn on to leave this area, but first, we want to head into the security room in this area on the floor above and grab the keycard which we need to leave.
Workbenches: 2/3 Now that we have the keycard, we have to turn the generator on to leave, but in doing so, a Bloater will spawn. So you can either run for the exit or fight; up to you. But once out of the area, we will run up some stairs and need to go through the first room on the right, and on the right will be a workbench. Remember to interact with it for it to count as found.
Comic: 2/3 Accretion When finished, head forward through the kitchen and the dining area while dealing with the hunters. Once we find the ladder needs to leave, and after the cutscene is over, climb up the ladder to the next floor. After going through the first double doors on the left, go into the room to the left and shimmy across to the other side. Once over the other side, the Comic will be on a table to the left.
Firefly Pendant: 2/3 Reed Now let's get back on track. We will have to drop down some broken stairs to the floor below. Once done, we are going to find 2 bathrooms to the left. We want to walk into the second one or the ladies' room. The Pendant will be in the second last stool, to the left of the toilet.
Training Manual: 3/4 Melee Knots When done, head back down the hall and there will be the next Training Manual on the first table on the left.
Optional Conversation: 11/14 Backdrop Once done in this little hall area, we can walk into the next open room. We want to turn right and head toward the backdrop. Wait for Ellie to walk over to the backdrop to get the prompt. Note: There will be 3 different times a prompt will appear, so make sure to do all 3 for it to count as 1 Optional conversation.

Financial District

When the cutscene ends, we can do two things: Kill all the hunters to then collect stuff or collect them in stealth. But even if you kill all of them stealthfully, the game will force you to go loud for story reasons.

Artifact: 13/17 Fireflies Note We want to head over to the freezer in the back of Don Fiocchi's shop. The Building is in the far back right of this area, right next to the blocked-off road at the end of this area. There will be a note in the freezer room.
Optional Conversation: 12/14 Hanging Body When head back over to the hanging body the hunters were before. Wait for Ellie to walk up to it for the prompt.
Workbenches: 3/3 After that, we are done with this area for collectibles, so be sure to look around for supplies. Once done, head on over to the far left-hand side of this area to get through a metal shutter. While inside, we need to grab the cart and move up against the wall to get over. Once over the wall, to our right will be a Workbench.
Artifacts: 14/17 Final Attack Note Alright, walking forward, we will jump over a table and be attacked.

Wait for Ellie to walk up to the sign for the prompt to talk.

When done, head down the alleyway and after a little bit, there will be some hunters and a Jeep with a turret hunting us. We want to cross to the other side of the road. Watch out for the turret, as it'll kill you easily. Just take it slow or run past this area. There is barely any loot here too.

On the other side, head through a window leading to an alleyway behind it. Keep running down the alleyway and enter the building to the right. Go upstairs and fight some more hunters. At some point, we will go through some offices and leave via the fire escape. We will cross over a few boards to an open window. Look around this apartment for loot and then exit by going through a window near the kitchen and then shimmy across to another window where another cutscene will happen.

With that last note collected, could you look around for supplies before following Henry. Once we do follow him through another doorway, a cutscene will happen, and it'll now be nighttime. I suggest making a save here. Follow Henry to the ground floor, and there will be two hunters; pick one and Henry will kill the other.

Now for this area, there is a special condition achievement called "Lights out", where while in stealth, turn off the generator near the gateway. It is both easy and hard to get, just don't have the light on you as you move up, and watch out for the roaming hunters, just take this slow. If you get spotted, you can just reload the last checkpoint or load the manual save to try again. The generator should be on the left-hand side of the gate, just underneath the spotlight. It is quick to turn off, so you could just turn it off and run for the gate if you want.

Once we get control, the whole place is looking for us, and they are well-guarded, so be on your game. If you kill someone with a rifle, you can now pick it up and use it within this chapter, so have fun with it.

Artifact: 1/4 Surgeon's Recorder What we want to do is get to the 6th floor. At some point, after climbing some stairs and opening the door to the floor, we want to head over to the counter on the right for a recorder.
Shiv Door: 1/1 Now the next thing to do is turn around and open the last Shiv door that is also behind the counter. Inside the Door will be a Firefly Pendant on the right.

Master of Unlocking

In opening the Shiv Door, we should get the "Master of Unlocking" achievement for opening all 13 Shiv Doors. If not, do new game + or use the chapter select in the main menu.

Master of Unlocking
Break into every locked door using shivs
Unlock all 13 Shiv-able doors.

Firefly Pendant: 1/1 The last Firefly Pendant will be inside the Shiv door, just to the right.	Stewart-Seume
Artifact: 2/4 Marlene's Recorder 1 Go back to the hall and head into the room that's to the left of the stairs we took. Walk in and on the right will be another recorder.
Artifact: 3/4 Marlene's Journal Head back out to the hallway and then walk to the left. There will be a double doorway on the far left of the hall. Head through the doors and then head inside the tent in front of us. Another recorder will be inside, on the far left of the tent.
Artifact: 4/4 Marlene's Recorder 2 Now the last collectible is in the hall right after the guard's last stand, basically. Clear the room or run past; up to you. But once you are past this area and through the door, take the first room on the right, and there will be one last recorder to the left of the bed.

Jackson

Comic: 1/1
Singularity
Well, this is it, the end. After the long car ride, we play this chapter as Ellie. All we gotta do is follow Joel, but there is one last Comic we need to pick up. Once we're over the fence, we want to walk slightly to the right and look for a broken truck near the rock wall. The Comic is on the seat.

Endure and Survive

And once we pick up the Comic, we will get the "Endure and Survive" achievement and we are done collecting collectibles for the base game.

Endure and survive
Collect all comics
Collect all 13 comics.

Now, all we have to do is follow Joel, and then the game will end after a talk. I wonder what they will do deal with this in a part: II.

The Last of Us Part 1: Outro

We are now finished with the base game; congrats! You should now have the "No matter what" achievement for beating the main game.

No matter what
Complete Part 1

Now we have to play the Left Behind DLC for a few more collectibles, and we are finished. If you are missing any achievements, you can either do a new game+ to get them or use the chapter, select in the main menu to play in a specific chapter.

Conversation: 9/12 Skeleseer Now we want to head over to the magic 8 ball that is a skull. So turn left and walk forward or to the left of where we entered the building first. We need to interact with it 8 times for it to count as 1 Optional Conversation.
Optional Conversation: 10/12 Bird mask We now want to switch our mask with a bird one. It should be on the shelf behind us.
Optional Conversation: 11/12 Witch And the last mask we need will be on the other side of the shelf. So just walk to the other side and wear it, then talk to Riley.

Optional Conversation: 1/3 Carousel ride After we control Ellie again, hop onto the carousel to get an Optional Conversation.
Optional Conversation: 2/3 and Jokes: 6/6 Once we're finished with the Carousel ride, Riley will give us the joke book, allowing us to get the final Joke of the game. We must go through all the jokes for this to count as 1 Joke and as an Optional Conversation.

With that, we will finally have the "That’s all I got" achievement if we have listened to all 6 jokes.

Not Everyone's Perfect

At some point, we will head to Raja's Arcade. Do not interact with The Turning arcade, instead look for the Jak X arcade in the back. After Elliie pretends to drive in it, we will get the "Not Everyone's Perfect" achievement.

Noboy’s perfect

When in the “Raja's Arcade”, look for The Jak X racing machine, and interact with it to unlock it.

Angel knives

When ready, head over to The Turning arcade. Now for this, we must defeat Black Fang without getting hit once. The cheesy way of doing this is to pause the game when the next lot of prompts appear to know them beforehand. Reload the checkpoint if you are hit.

Angel knives
Defeat Black Fang without getting hit
In “Raja's Arcade”, you must get every prompt right not to get hit. If hit, you can just reload the checkpoint.

Artifact: 2/2 Duct Recorder At some point, you will be inside a vent. Take the first left and at the end will be a dead body. Next to it will be the last Artifact and the last Collectable of the game.

Throw a brick or bottle near the hunters to trigger the infected to attack the hunters. Once one of the hunters is killed by an infected, we will get the "Live bait" achievement. Here and in a tech shop are the only times we can get this.

[atlchaotic*]

Hey, I think you missed captains letter in pittsburgh. I found it just by wandering around but I didn't see it in this guide. I don't know if I'm blind or sum, but I think you just forgot to mention it. If it's not the case and I'm just dumb then correct me

[I'M SAYING THE N WORD]

@»SoD« Thekillergreece
Thank you. That was the plan of the guide.
I aren't ready for it as I don't like it. I will however give it another shot to see if the story is still the same to me or not. Therefore I am making a guide for it. It probability wont be as good as I have only played it once, but will edit it if needed

[»SoD« Thekillergreece]

Very useful guide. I hope you are ready for TLOU Part II. :)
