The Last of Us 2 has 8 Training Manual Locations. The Training Manuals are a type of Collectible that unlocks new Player Upgrades (Skill Trees). You can then use Supplements to unlock individual Skills.
All of these items (Training Manuals, Supplements) are also part of the All-in-One Collectible Guide, which is recommended if you also want the other Collectibles. If you only need the Training Manuals specifically, they are listed below with their locations. While there are 10 Skill Trees in total, 2 of them are automatically unlocked at Chapter 2: Waking Up & Chapter 24: The Stadium. The remaining 8 requires a Training Manual each. The good news is there are more spawns than you need. If you miss one Training Manual Location, the next will have the Manual you missed. For example, if you missed the first location, then the second location will have the first Manual and so on. So to make things easier to follow, it’s highly recommended to not miss anything here. There are some bonus spawns. Below are the first spawn points for each Manual. Having unlocked all 10 skill trees from Training Manuals unlocks the Journeyman 
trophy. However, unlike other Collectibles that you can get via Chapter Select this won’t work for Manuals. You must hold all Manuals at the same time (find them in a continuous playthrough) to pop the trophy.
Note: Players who got the Pre-Order Training Manual Bonus will automatically have the first Manual in their backpack. For those players the Crafting Manual won’t spawn because you already have it. Those with the Pre-Order DLC will also get an additional spawn at the end of Chapter 9 (Downtown) in the hotel, in the bedroom upstairs (this won’t be there for players without the Pre-Order DLC).
Training Manuals:
- Crafting
- Stealth
- Precision
- Explosives
- Covert Ops
- Close Quarters
- Firearms
- Ordnance
Training Manual #1: Crafting
Head north to the broken highway bridge between 6th Ave & 7th Ave. There’s a firetruck on the bridge. Climb the parked military truck next to the bridge, from its roof you can jump to the firetruck. Pick up the fire hose 
and throw it down the bridge 
+ 
to a highway segment with an overturned truck. Climb down the hose 
and swing off it to the rolled over truck, in it is the first training manual in the game. These unlock new skill trees for you on which you can spend Supplements (press 
Touchpad to open your backpack and 
scroll to the skill trees). Note: Players with the Pre-Order Training Manual DLC will already have this Manual in their backpack and it won’t spawn here. Instead, those players will find the “Stealth Manual” early at the end of Chapter 9: Downtown in the hotel, bedroom upstairs. This won’t affect the trophies, already having it in your backpack will suffice and doesn’t void any trophy.
Training Manual #2: Stealth
After jumping down the Motel (or pushing the dumpster to jump the fence), walk all the way to the left to find a book store across from a gas station. Enter the book store and in the room with the cash register you can find a Training Manual. Note: Players with the Pre-Order Training Manual DLC can already find the “Stealth Manual” early at the end of Chapter 9: Downtown in the hotel, bedroom upstairs. For players without the DLC it won’t spawn until Chapter 11.
Training Manual #3: Precision
Halfway through the chapter you will push a dumpster up a road and use it to jump into a building with a Workbench. Leave this building and you’ll come to an area with shops on the left and right. Enter the first shop on the right “Goldstar Liquor”. Drop down into the cellar, beware of 2 Shamblers down there. Exit the cellar where the light is coming from to reach a nursery. The Training Manual is on the floor there.
Training Manual #4: Explosives
After passing under the overpass on the main road (just after a taxi), take a left turn to reach a long apartment building. In front of the closed main entrance there’s a parked truck. Climb on its roof, from there jump onto the apartment building’s roof. Enter through the window and go into the first room on the left. Interact with the Workbench there and a human enemy will attack you from behind. Kill him and his gang, then head inside the room they stormed out of to find a Training Manual.
Training Manual #5: Covert Ops
When you have to carry a ladder and use it as a bridge to a boat that’s hanging from the ceiling, check inside the hanging boat for a Training Manual location.
Training Manual #6: Close Quarters
Shortly after the start of the chapter you climb a fence and split up with Manny. In front of you will be a shop called “Spicy Dumpling”. Continue past this shop downstairs. Before going into the next building “Tang Fabrics & Imports”, climb through the broken window on the left for a room with a Training Manual location.
Training Manual #7: Firearms
After the boss fight against the big woman with a pickaxe, enter the next building “La Rosa’s Auto Shop”. Enter the hallway on the right and immediately turn right again into a side office. There you find a Training Manual on a desk.
Training Manual #8: Ordnance
On the top deck of the ship, inside the safe at the ship’s helm (the ship’s “steering wheel”). The safe code is 90-77-01 and it contains the last Training Manual.
Bonus Training Manual Location
Just in case you missed a Training Manual, they will keep respawning in a few more “backup spots”. One such spot is at the start of Chapter 38: The Island. After climbing up the first ladder in this chapter, check the back of the truck on the left. A Coin Collectible is also in there. If you already found 8 Training Manuals it won’t spawn any more Manuals because you already have them all.
That’s all of the Training Manuals for unlocking Player Upgrades in The Last of Us Part II.

I found ‘stealth’ the second manual, in the first hotel before you get to capital hill and before you get taken prisoner. Right before you go into the room where tommy tortured the two guys for info. It was on a table in one of the rooms.
Found all manuals no trophy idk why I’m having problems with the trophies seems very giltched same with the safes
Do I have to pick up the 2nd spawn of the Crafting manual to get this trophy?
Or will the fact that I already have it in my inventory from the pre-order dlc suffice for the trophy?
Having it from the Pre-Order will suffice. The trophy only wants you to have all Training Manuals, not visit all their spawns. There are more Training Manual spawns than you need anyway.
I found the Covert Ops manual but it didnt give me my upgrade & i didnt realise until i need to make shivs ??♀️ What do i do? Im further along now & i need shivs badly!
I claimed all the manuals via chapter select but i dont get the trophy. Can you help me out?
You must have unlocked all Manuals in your backpack at the same time, chapter select resets them and doesn’t count. It works differently than the “real” collectibles (the ones that show in chapter select).
Manuals must be found in one continuous playthrough.
I missed one manual (Hillcrest location) during my playthrough and after that via chapter select picked this one and just got the trophy.
I do not have the Precision training manual but I have the Explosives. I started a new game +, I am only one chapter 10, but I went to the location of the Crafting training manual and there was nothing there. I am not too sure how accurate the following statement is – “If you miss one Training Manual Location, the next will have the Manual you missed.”
