Charted! – Speedrun
Complete the game in 6 hours or less

This Uncharted 4: A Thief’s End Speedrun Walkthrough shows the full game from beginning to end (Cutscenes are not included).
The “Charted! – Speedrun” trophy requires you to beat the game in 6 hours or less. I did it in 4 hours, 42 minutes, 34 seconds.
Most importantly, cutscenes add to your total time so you must them all. Some are unskippable.

I also ended up with 83% shot accuracy. You need 70% accuracy for the “Sharpshooter” trophy.

Speedruns Tips:
– CUTSCENES ADD TO YOUR PLAYTIME! YOU MUST SKIP THEM!
– The timer stops during loading screens and when you pause the game.
– Play on Explorer difficulty (does not disable trophies)
– Enable Auto-Aim in options (does not disable trophies)
– Enable Infinite Ammo & Use the Barok .44 revolver from weapon select. It kills almost everything in one hit. Cheats are unlocked after beating the game for the first time on any difficulty (Cheats don’t disable trophies)
– Remember that you can fire from the hip while running past enemies. Works great at close quarters.
– You don’t need to kill every single enemy. Sometimes you can run past entire enemy encounters without killing.
– You are allowed to create manual save games and can quit the application. There’s no need to do it in one sitting, the trophy will unlock regardless.
– If you have a progression glitch simply quit the application and continue the story, it should load up fine (infinite loading screen, game crash, NPCs not doing what they are supposed to).
– If you die or restart checkpoints it will keep counting your time (it won’t reset the time to the last checkpoint).
– You can check your playtime anytime in the statistics. Compare with the time in the video to get an idea where you’re standing. I had plenty time left for the trophy.
– The Puzzles can cost you a lot of time if you don’t do them perfectly. Look them up in the video, I show them as quickly as possible.

All in all, beating the 6 hour requirement isn’t too difficulty with auto aim and cheats. Just remember to skip every cutscene.

Charted! – Crushing
Complete the game in crushing mode

Beating the game on crushing unlocks the silver trophy “Charted! – Crushing”. Crushing is available from the beginning. It is the highest difficulty in the game.
If you want to make things easier you can enable cheats in the bonus menu (e.g. infinite ammo). You can also use weapon select from the bonus menu to use an overpowered one-hit kill weapon. Cheats are unlocked after beating the game for the first time (any difficulty). Cheats do NOT disable trophies! You can get the “Charted – Crushing!” trophy with cheats enabled.
You have to beat every single chapter on Crushing to get the trophy. Beating only the last chapter on Crushing won’t unlock it.

The hardest part by far is the endboss. He kills you in 1-2 hits. His attacks are also much quicker than on lower difficulties. You must evade his attacks by pressing Triangle/Circle. When he strikes from the left you must press Triangle, when he attacks from the right you press Circle.
My strategy here was to quickly press circle at all times. So if he attacked from the right I would automatically block it each time. I only needed to watch out for attacks from the left. When he attacked from the left I pressed Triangle real quick.

Some of his attacks (especially spin attacks) are really confusing and it’s hard to see from what side he will attack. After a while you’ll get the hang of it. You just need to learn all his attacks patterns.
To make the fight easier you may want to activate the Slow Motion cheat in the bonus menu (under Game Play Modifiers). It will give you a lot more time to block and you shouldn’t have much trouble beating the boss this way.

Uncharted 4 Full Collectible Text Guide & Collectible Overview

Relic Finder
Find the Strange Relics
There are 3 “strange” relics you must find for this. They all count as treasures.

Chapter 9: Strange Pendant
After solving the puzzle with the water bucket and 3 crucifixes you must jump down the cliff on the right side. Here you can attach your rope and swing to a platform with a skeleton on it that has the pendant.

Chapter 12: Strange Relic
This is after following the arrows with your boat. Shortly after you and Sam get split up (because of a rope bridge breaking apart) you will come to an old tower on top of the island. From here you must use your rope and slide down some mud. Now head left. There’s a small hill you can climb. From the hill you must make a far jump into the abyss and attach your rope last second. The rope is really far away and hard to see. It will let you swing to a platform with a big bowl on it. In the bowl is the strange relic.

Chapter 21: Strange Fruit
This is inside the cave near the end of the mission. You will have to attach your rope to a wooden structure and swing down. As you swing down you will see Avery’s pirate ship in the water below you. Now rapel down and swing to the little cave entrance in front of you, on the right side. It’s far away and easy to miss. Inside this cave is the last strange item. Trophy unlocked!

Still Got It!
Hit all targets in the attic with the toy gun
Chapter 4: A Normal Life
At the very start of chapter 4 you will pick up a toy gun. There are 4 red targets hanging from the ceiling. Shoot all 4 with the toy gun to unlock the trophy.

Ghost in the Cemetery
Get through Scotland cemetery combat encounter without killing or being seen
Encounter: Dormitories (Chapter 8).
Select the Dormitories encounter from the main menu (chapter 8). This is the graveyard section of chapter 8 after solving the puzzle in the catacombs.

Getting past all enemies unnoticed is pretty easy. The trophy pops when you’ve opened the gate at the other end of the graveyard. You are not allowed to attack anyone and may not be detected. First, climb around the cliff near the catacomb exit. Then go through the bushes / tall grass. Enemies cannot see you while you’re moving in the bushes. You can climb the wall on the right when all enemies have walked away. Now you hear two guards talking to each other in front of the gate. Hang at the back of the wall while they talk. When they’re done talking, climb up and hide for about 5 seconds until the third guard walks away. When all 3 guards on the upper area are facing away you open the gate.
If you are being detected simply restart the checkpoint or encounter.

Trials and Tribulation
Solve the first trial in Scotland in 10 moves or less
Chapter 9: Those Who Prove Worthy
Shortly after the start of chapter 9 you will come to a room with a puzzle. There’s a big wheel with a switch to the left. Activate the switch to get a water bucket. Fill it with water and bring it back to the wheel. Now the part for the trophy starts. You may only rotate the wheels 10 times to complete the puzzle.
The puzzle is randomized, it’s different on each playthrough regardless of difficulty settings. So it’s impossible to give detailed instructions. I was able to complete mine in 6 moves because I got a lucky starting combination, but yours will likely be different.

The final picture has to look like this: White cross on left, big cross in the middle, black cross on the right, water bucket in middle of top wheel.
Just try around and restart the checkpoint when you know the solution for your puzzle.

Not a Cairn in the World
Knock over all rock cairns in Madagascar

For this you must knock over all 16 rock cairns (rock piles) with your car in chapter 10. Simply drive over them and they will fall apart.
All of them are in chapter 10. Their locations are as follows:

#1 – In front of where you start.
#2 – In the bigger area shortly after the start (area with waterfall on the left).
#3 – Same area as previous cairn, but at the end of the area (where you drive up the mud).
#4 – After driving up the mud, before the wooden bridge on the left.
#5 – After crossing the wooden bridge on the left.
#6 – Shortly after passing the bridge you drive up a muddy hill. After that you come to a new area with a small river and you must drive up a large rock. On the rock is a cairn.
#7 – After driving up the second rock on the right (same area as previous cairn).
#8 – You’ll drive down a muddy hill and see some ruins in front of you. Before the ruins on the left is a cairn.
#9 – After the last cairn you jump down a little rock and come to a relatively small circular area. At the end of this area is a cairn.
#10 – In the area after destroying a wooden bridge with the winch. When Sully talks about Nadine.
#11 – In the very large area on your way to the beacon. It’s at the start of that area, after you see some trucks driving away in the distance.
#12 – Same area as before, further up the hill
#13 – Same area as before, on the hill on the left side with the manmade sculptures.
#14 – Same area as before, near the top of the hill (but before the beacon). This is the best hidden one, it’s standing in some tall grass. Hard to see. It’s just before making a right turn to the hilltop with the beacon. To the left of it is a path that leads to a village with enemies.
#15 – On the hilltop where the beacon is located. In front of the beacon.
#16 – After the second beacon / tower, on the right side of a cliff. You’ll drive past it, hard to miss this one.

Don’t Feed the Animals
Play with the lemur in the market and let it steal your apple
Chapter 11: Hidden in Plain Sight
At the very start of the chapter go to the left of the market square. There are two ladies here who want to sell some apples to you. Buy an apple and go to the man with the lemur at the end of the market. Press triangle to interact with him. As you walk towards Sully the lemur will climb your shoulder and steal the apple – this unlocks the trophy.

I Can See My House From Here!
Climb to the very top of the Clocktower in the City
Chapter 11: Hidden in Plain Sight
As the trophy description says you must climb to the top of the clocktower. This can be done when you have to ring the bell near the top of the tower, but the handle breaks. Before you jump on the bell you must climb the wall outside the building. On the area above the bell is a treasure and some wooden beams. Go across the beam in the middle and you’ll be able to climb the back of the wall all the way to the top. Now just stand on the pillar on the rooftop and the trophy unlocks.

Glamour Shot
Take a picture during the founders puzzle when Sully says cheese
Chapter 11: In Plain Sight
After ringing the bell at the top of the tower in chapter 11 you will come to a puzzle room. After inspecting 3 pirate portraits Sully gives you his phone. You are supposed to take a picture of the pirate sigils, but instead you need to aim the camera at Sully and take a photo when he says cheese.

Stage Fright
Just prior to City Chase, stand perfectly still for 30 seconds (stage demo fail)
Chapter 11: In Plain Sight
After completing the Founders Puzzle in the church you will go back outside to the market square. After opening a door, Sully and you will lean over a balcony (cutscene). Put your controller down and don’t do anything for 30 seconds. Then the trophy pops.
This is a reference to a mess-up at Naughty Dog’s E3 demo of this level. A developer couldn’t find the controller on stage and so Nate was just standing around for 30 seconds and they restarted the demo. It appears the guys at Naughty Dog have a good sense of humor though, and made a trophy of it.

Marco Polo Returns!
Play in the ocean near the sunken ship
Chapter 12: At Sea
From the start of the chapter drive to the left of the big island. There’s a sunken pirate ship here. Swim in the water by the ship and the trophy unlocks. Nice and easy.

On Porpoise
Get three dolphins to follow the boat
Chapter 12: At Sea
When the chapter starts you will be driving a boat. Drive it to the back of the main island. There are three dolphins in the water here. We will start with the one closest to the tower island.

#1 – Far out in the water (at the back of the tower island) you will see 3 rocks. Near those rocks is a dolphin (to the left of the rocks when you come from tower island).
#2 – When you drive in a straight line between #1 & #3 you’ll find this dolphin. At the back of the large island far out in the water. He is swimming around a lot, so his location varies slightly. Sometimes he is further out, sometimes closer to the island.
#3 – Near the island with the sunken pirate ship.

Basically, you just need to drive in a straight line and should get all 3. Because they are swimming around a little bit their location varies. They are always in the same distance to each other, but sometimes they are further out in the water, sometimes closer to the main island.

Peaceful Resolution
After being marooned, leave everyone alive until the Treasury
This trophy takes place over the course of chapter 13 & chapter 14. It will unlock at the start of chapter 15.
You cannot unlock it in encounter select. It has to be via chapter select / in story mode.

There are 3 enemy encounters in total. One in chapter 13, two in chapter 14.
In chapter 13 you can simply rush past the enemies. In chapter 14 Sam will be with and if you get spotted he will start killing enemies. Neither you, nor Sam are allowed to kill anyone. If you do, you must restart the checkpoint.
In chapter 14 you have to get through all encounters in full stealth. Otherwise the enemies spot you and then Sam kills them.

Sometimes, when restarting a checkpoint some enemies simply disappear. This is nothing to worry about and won’t void the trophy. In some sections you may actually want to restart checkpoints just to make more enemies disappear.
Just stay in stealth and play it safe.

Just Floor It!
Drive away in the jeep with Elena without killing any enemies

Chapter 17: For Better or Worse (Encounter: Get to the Car)
During the first enemy encounter in chapter 17 you must steal a car. Neither you, nor Elena can kill anyone! If you are detected Elena will kill enemies. So you must do it in stealth. Climb around the cliffside and use the rope to get past the enemies unnoticed. On Crushing difficulty they will likely spot you, so put the difficulty to explorer.
Drive off in the car and make sure you don’t run over anyone. If Elena shoots someone during the car ride it will count as a kill too. So do your best to enter the car unnoticed and it should be fine.

Swordmaster
Perfectly parry in the sword fight without getting slashed or stabbed
Encounter: The Duel (Chapter 22)
For this trophy you must beat the endboss without getting hit. You can do this via encounter select on explorer difficulty. If you do get hit you can restart the checkpoint and still get the trophy in the end.
Your opponent’s attacks are very slow on the easiest difficulty (explorer). If you try it on a higher difficulty it will be very hard to do.
After beating the game you also unlock the Slow Motion cheat. The cheat does not disable the trophy. So if you have any trouble, enable the cheat and all attacks will be in slow motion, giving you enough time to react.

You must evade his attacks by pressing Triangle/Circle. When he strikes from the left you must press Triangle, when he attacks from the right you press Circle.
My strategy was to quickly press circle at all times. So if he attacked from the right I would automatically block it each time. I only needed to watch out for attacks from the left. When he attacked from the left I pressed Triangle real quick.

For some of his attacks it’s hard to see from what side he’s gonna attack (e.g. spin attack). It will take some practice to get to know all his moves. After a while you’ll get the hang of it. Some of his attack combos are always the same at certain points of the fight. Most of the advanced attacks (like the sword spin) hit from the right side.
Because you’re allowed to restart checkpoints it’s not so bad. There are several checkpoints throughout the fight.

Best Score!
Beat the Highscore in the Crash Bandicoot Minigame.
Chapter: Epilogue
You can only do this in the epilogue (last chapter). It doesn’t work in chapter 4 when you play the Crash Bandicoot game for the first time. The reason being that you have an extra life in the Epilogue which gives you 500 bonus points.
You must beat the highscore of 3500 points. With a few tries this is quite doable. You need to pick up most of the apples, don’t die, and complete the game as quickly as you can. If you are short a few points it’s because you didn’t pick up enough apples or missed the bonus life from one of the boxes. The bonus life is found in a wooden box relatively early in the level. If you don’t pick up the bonus life you cannot beat the highscore.

Hangman’s Bullet
Perform 20 headshots from the rope
Encounter: Drawbridge (Chapter 10)
Select the Drawbridge encounter from the main menu (chapter 10). Make sure you put it on Explorer difficulty and disable auto aim in the control options. There are two ropes in this encounter. The one on the right side works best. Use the rope and wait until it stops swinging. Then shoot the enemies in the head. The AK-47 (or any other assault rifle) work really well for this. You can fire in bursts and should easily get a headshot. The enemies aren’t far away. Some will be standing right in front of you on a building. After killing a bunch of them restart the encounter.

Do not complete the encounter! Leave one alive and restart checkpoint! Each time you load up an encounter your kill counter resets. This means you must do 20 rope headshots in a row via checkpoint restart. If you quit out to the main menu your progress will be lost.
This should only take ~5 checkpoint restarts as you can get multiple headshots on each run.

I Thought I Heard Something
Perform 30 vertical stealth takedowns
+ Shh Sleep Now
Stealth take-down 30 enemies
Encounter: Bridge (Chapter 8)
The bridge encounter in chapter 8 is perfect for this (you can select it from the main menu). Doing a vertical stealth takedown (drop onto enemy below you) automatically counts as a “normal” stealth takedown at the same time. So when you get the “I Thought I Heard Something” trophy you will automatically unlock the “Shh Sleep Now” trophy with it.
The very first enemy of this encounter is perfect. After a few seconds he will walk towards you. Then you can drop onto him for an instant knockout. Restart the checkpoint and repeat 30 times.

Be aware that if you quit the encounter you’ll have to do 30 takedowns again! You must use checkpoint restart 30 times. Your kill counter resets every time you load up an encounter.

Leapfrog
Defeat 10 enemies in a row, alternating gunplay and hand-to-hand
Encounter: Ruins (Chapter 8)
Select the Ruins encounter from the main menu (chapter 8). This is a very good place early in the game to get the trophy done.
Play on a low difficulty. Always kill one enemy with gunfire, then one with melee attacks and repeat. You need 10 kills total (5 gunfire, 5 melee). All the enemies in this area are really weak so it should be easy. Use Melee kills on the enemies on the ground and gunfire on the ones on the ruins. You can’t reach the enemies on the ruins, so you must reserve your weapon kills for them. If you shoot too many on the ground you might run out of enemies.

Rushing Roulette
Defeat enemies with a pistol, machine gun, and grenade, in that order in 15 seconds
Encounter: Drawbridge (Chapter 10)
Select the Drawbridge encounter from the main menu. You will start out with an AK-47, a pistol and a grenade. There are many enemies close together here.
Just like the trophy description says, you must do the kills in a specific order: Pistol, AK-47, Grenade. Kill 3 enemies very quickly with the different weapons and the trophy will unlock. Very easy.

Butterfingers
Make 10 enemies drop their grenades
Encounter: Market Escape (Chapter 11)
The perfect place to do this is the start of the Market Escape encounter of chapter 11. Make sure you put the difficulty on crushing! Enemies throw a lot more grenades on crushing. On lower difficulties it won’t work so well. Crushing is unlocked from the beginning. You can change difficulty anytime in encounter select or in the pause menu.

At the start of the encounter there are 3 enemies. Kill the two on the left that come running. Once they are dead, the remaining enemy on the right will fire his gun at you and follow up with a grenade. Before he throws the grenade (while he is holding it in his hand) you must shoot him. Then he drops the grenade and blows himself up. Restart the checkpoint to farm more kills. If you quit the encounter your kill progress will be reset. So make sure you do 10 in one sitting.
To make things easier it is highly recommended that you enable the cheat “Bullet Speed Mode” from the bonus menu. It will greatly slow down time while aiming. This makes it much easier to time your shot. Usually, after the two other enemies are dead, he shoots at you once, goes back into cover and then throws the grenade.
Try to kill the other 2 enemies as quickly as possible with clean headshots. If you take too long, Sully might kill the enemy on the right.

Boom County
Defeat 4 enemies with the same explosion (all explosive items and weapons are allowed)
Encounter: Showdown (Chapter 20).
The easiest place for this is the Showdown Encounter from chapter 20. Select it in the main menu and play on explorer difficulty. After killing the first 3 enemies of this area, 4 new ones will spawn close together on a rock. There is a rocket launcher sitting on one of the boxes here. Pick it up and shoot the 4 enemies after they jump down the rock. Aim at the enemy that carries a rocket launcher, he has the strongest armor.
This should easily kill all 4 of them. If you don’t get it on your first try simply restart the checkpoint.

Defeat 10 in 60 — China Lake GL
Defeat 10 enemies in 60 seconds with the China Lake Grenade Launcher
Encounter: Drawbridge (Chapter 10)
First you should beat the story to unlock weapon select and the infinite ammo cheat. Without infinite ammo this will be very hard to do because the grenade launcher comes with only 3 shots.
You can buy cheats from the bonus menu and they don’t disable trophies.

Now load up the Drawbridge encounter in chapter 10. It’s important to note that the China Lake Grenade Launcher can only be selected during certain encounters. The Drawbridge encounter is one of them.
Activate the infinite ammo cheat and use weapon select to get the China Lake GL. Now shoot the enemies and you should get this easily. You can kill 10 of them in less than 20 seconds. Without the infinite ammo cheat you would run out of ammo too quickly.

Hang Tough!
Destroy 10 vehicles while being dragged from the rope
Encounter: Convoy (Chapter 11)
Select the Convoy encounter in chapter 11 from the main menu. Here you will get dragged by a rope. At the very start of the encounter you can shoot vehicles with your pistol while being dragged. If you shoot them often enough they explode.
Put the difficulty on explorer for this and enable auto-aim. Then it’s very very easy. Destroy the first two cars and repeat the checkpoint. Keep repeating this until the trophy pops.
When you quit the encounter your progress towards this trophy will be lost. So make sure you destroy 10 vehicles in one sitting.

Run the Table
Defeat enemies with a stealth attack, melee attack, headshot, and explosives, in that order, in 15 seconds
Encounter: Dormitories (Chapter 8)
Select the Chapter 8 Dormitories encounter from the main menu. Any difficulty from explorer to hard is fine for this. The timer starts when you do the stealth kill. Remember you must do kills in a certain order: stealth, melee, headshot, explosive.
As soon as the encounter starts, rush to the enemy on the left wall as quickly as you can. Do a stealth kill on him, then roll away and do a melee kill on the other enemy on the wall. If you’re fast enough and roll away he won’t see you. If you’re too slow and don’t roll away you might get spotted and Sam will kill the enemy.
After the melee kill you’ll want to jump down into the large enemy group. Use the AK-47 to go for a quick headshot and immediately do a quick throw with dynamite (press R1 for a short moment, don’t hold it down to aim!). The quick throw isn’t very accurate and sometimes misses. But the dynamite has a huge blast radius so it should be fine.

It may take a few tries to get the timing down. If you didn’t get the trophy simply restart the encounter to try again.

If you have too much trouble with it you may even activate the slow motion cheat in the bonus menu (unlocked after beating game on any difficulty). The game counts time differently in slow motion.

Hitting a Brick Wall
Defeat 5 armored enemies with melee only
Encounter: Avery’s Tower (chapter 10)
Select the Avery’s Tower encounter from the main menu (chapter 10) and play it on explorer or light difficulty. There are two armored shotgun enemies here. First you need to do a jump takedown to take their helmet off. Then follow up with melee attacks. You are not allowed to shoot them at all (not even the helmet).
You can jump on them from the ruins.

Simply restart the checkpoint and repeat until you have 5 takedowns.

Wingman
Perform 10 combo buddy takedowns
Encounter: Laundry Fight (Chapter 2)
A good place for this is during the fist fight in the prison laundry room (end of chapter 2). You can go there via encounter select.

When one of your friends punches an enemy you must attack that same enemy. Then you will see an animation where both of you knock out the enemy together. There are infinite enemies spawning in that room, so you can take your time (just don’t attack the boss enemy or the encounter will end).

Cliffhanger
Pull 20 enemies over when hanging from a ledge
Encounter: Evasion (Chapter 7)
Select the Evasion Encounter from the main menu. The first enemy in this encounter can be pulled while hanging from a ledge (press square while you’re on the ledge under him).
Restart the checkpoint 20 times and repeat.

Be aware that your kill count resets each time you start an encounter. So if you quit the encounter you need to do 20 kills again. You must use checkpoint restart 20 times in a row.

I Accidentally All the Guns
Use every weapon in the game
For this trophy you must kill an enemy with every weapon. There are 27 weapons total. The first 21 you can get from weapon select in the bonus menu after beating the story. The other 6 you must find yourself.
You can get all the weapon kills in encounter select. Your progress will be saved instantly and will be saved when you quit the encounter.

The following 21 weapons you can get from weapon select in the bonus menu:

1. Aegis 9mm
2. Fossa R-81
3. Raffica
4. Pistole
5. Barok .44
6. Flintlock
7. Para .45
8. AK-47
9. XCR
10. FAL
11. ARX-160
12. HS39
