-Scratching at the Past:
"Found all of the Secrets"

Awarded for collecting all 50 of the secrets. These can be found throughout the game as interactive story collectibles. Make sure to rotate and inspect objects thoroughly.

You can use chapter select to collect missed collectibles.

Here is a video guide of all 50 secrets and also the paintings. I do not own this video, it belongs to "100% Guides". Leave a like if you found it helpful. https://www.youtube.com/watch?v=peJfgOuLisY
-The Statement of Randolph Hodgson:
"Found every part of Randolph’s journal"

There are 10 journal pieces to collect. They play a little video after finding them. They are part of the 50 collectible secrets needed for the above achievement. Under the secrets tab they're the 10 silver circles.

-Golden Path:
"Five characters survived the finale"

Awarded for saving the five main characters through the entire story.

Tips:

• Pass every QTE, Keep calm and combat encounter.
  
• Try and keep relationships at good levels.
  
• As Salim near the start, learn that the monsters react to sunlight.
  
• After Nick and Salim take on the monster, reassure Salim that he will be okay.
  
• Later Eric should discover that the monsters burn under his UV wand.
  
• Take the stake as Jason or give it to Nick.
  
• Get rid of Clarice as early as possible or abandon her as Rachel.
  
• Interact with the guy from the prologue trapped in the yellow goo on the way through the city.
  
• When playing as Rachel in the Star Map room do not knife the phosphorus canister and do not ask Jason to shoot. Convince him you are still in there.
  
• Eric should use the UV light on Rachel saving her from the parasite.
  
• Rescue Salim and bring him to the elevator.
  
• Do not die to any of the infected humans. Can be achieved by passing QTEs.
  
• In the final house during the eclipse don't mess up any QTEs.

-Six Minutes of Night:
"Everyone died in the finale"

Awarded for having all five main characters survive up till the finale and then have them all die during it. If you have a save file from "Golden Path" achievement, load up the finale from that and then have them die in the house during the eclipse.

-Final Girl:
"Only one character survived the finale"

Any single surviving character will work for the achievement. If you have the save file for "Golden Path" achievement, you can load the final chapter and play it out normally.

In the final house any characters left alive that you want dead you can fail their respective QTEs and pass the person you want alive for the achievement.

Note: The name of the achievement is just a reference to a horror trope (prominent in Slashers) where the final survivor is often female and referred to as the 'final girl'.

-Until Death Do Us Part:
"Rachel became infected and killed Eric, or Eric killed her"

Keep all characters alive. In the Star Chamber do not use the knife on the phosphorus round as Rachel. Then make sure Jason does not shoot Rachel but refuse to go into the cocoon. Rachel will then run away and escape.

Later on at the top of the elevator she will attack Nick and Eric if Jason and Salim are alive still. Fail all QTEs and she will kill Eric.

-Double Tap:
"Eric and Rachel both died in the same explosion"

During the chapter "Bloodbath" have all characters survive up to this point. Then as Jason choose to put the charges to the side, "Cautious".

During "The Signal" chapter, while playing as Rachel choose to retreat and then as Nick choose "Stick to the walls!". This will cause Eric and Rachel to die to the tripwires.

-Climbing out of Hell:
"Rachel survived after rejecting both her lovers"

Reject both Nick and Eric throughout the game and have Rachel survive. I recommend keeping relationships as Rachel with Nick and Eric negative as possible.

When the three of them reach the place where Jason drew the arrow on the floor before heading down the elevator, she will break up with both. After this just keep Rachel alive.

-Into the Sunset:
"Salim returned home to his son"

For this achievement you must keep Salim alive and have good/okay relationships with the other protagonists. If you called in Air Support Salim will not have time to go find his son, so refuse Air Support as Eric at the start of the game.

It is also quite possible that if Merwin survives long enough to fix the radio Salim will not be able to return home to his son. To avoid this just kill off Merwin before "The Signal".

-Full Clearance:
"Clarice killed Eric after becoming infected"

When climbing out the chasm as Rachel with Clarice, allow Clarice across. Later during "The Assault" Eric will be killed by Clarice if you keep convincing people not to kill her and bring her along.

While fighting waves of 'demons' in the sacrificial chamber, succeed Eric's QTE against the prologue character and everyone else's. Afterwards Eric will die to Clarice without the player being able to do anything to avoid it.

Make sure to avoid the tripmines that you placed in an earlier chapter. You must remember where you placed these. More info soon.

-Lost in Time:
"Rachel was not rescued from her cocoon"

Have Eric die before reaching the City. I recommend letting him fall down the hole in the Chapter "The Ancient One". This can be done by helping Nick and then failing the QTEs.

Interact with the prologue character covered in goo while travelling through the City.

Doing so will force Rachel into the cocoon to stop her from turning if she tells Jason not to kill her.

Then make sure she is not rescued by killing Nick while he goes to plant the bombs and kill Salim and Jason by dying in the eclipse by failing QTEs or by other methods.

-Start Thinking Like a Marine:
"Chose only Head decisions"

Complete a full playthrough while only picking the Head decisions. Every choice in the game will be marked with a brain (head) icon or a heart icon. If no Head icon is available, pick nothing/wait for time to expire.

NOTE: Unlike previous Dark Picture titles this game doesn't have an achievement for all Heart Choices.

On the pause menu it will tell you if you have made only Head decisions on that playthrough. If you make a mistake it will no longer be present.

-Illuminating Evidence:
"Eric discovered the unexpected effects of the UV wand"

Unlocked when Eric uses the UV wand on the dead 'demon' during the autopsy. It is possible that Salim needs to be kept alive up to this point and have him discover the 'demons' weakness to sunlight as well as him not hiding after helping Nick with the 'demon'.

-Let Me Have a Go!:
"Three characters used the UV wand to attack the creatures"

This achievement requires very specific decisions. I recommend reading the information below and replaying from the chapter that you need to start from using your save files or doing a full playthrough if needed.

Note that in general, Eric and Nick's relationship needs to be positive.

Here is a step by step walkthrough (Thanks wtfd00d):

• In "The Briefing", make sure Eric takes the phosphorus canisters. Agree to Air Support.
  
  
• In "After The Fall", make sure that Salim discovers the sunlight is the 'demons' weakness.
  
  
• In "The Truce", pass Nick's QTEs when flanking the creature with Salim. Assure Salim he will be okay and later Salim will tell Eric of the sunlight weakness. Later Eric will kill Joey with the UV light (UV kill #1).
  
  
• In "The Assault" - Salim must shoot the creature on Rachel, not the one going for him. Later Rachel must choose to save Eric instead of running and she will pick up the UV light (must pass the QTE) and kill a creature (UV kill #2).
  
  
• In "The Ancient One", fail Eric's Stay Still mechanic so that Nick gets attacked by the 'ancient warrior'. Choose to save Nick and pass the QTEs. Next have Eric 'say nothing' two times to Rachel when she says its over.
  
  
• In "Strange Aeons", Have Rachel kill herself with the knife and the phosphorus canister.
  
  
• In "The Vault", Eric will give the UV light to Nick if their relationship is not negative. Salim must not spot the cocoons in the upper left with the binoculars when Nick goes to plant the charges.
  
  
• Then as Nick, choose to go left instead of right and fail the Stay Still mechanic. Have Nick choose to retreat and he will use the UV light on the creature that follows him if he passes the first QTE and fails the second. (UV kill #3) earning the achievement.

Here is a condensed Video guide by '100% Guides' if you want visual representation of the bits described in this guide: https://www.youtube.com/watch?v=Vwdl43e_REY&ab_channel=100%25Guides

-The Sword and the Shield:
"Kurum and Balathu chose to fight together"

This achievement is obtained in the Prologue. Towards the end of the Prologue choose the option to be 'Respectful' and NOT 'Arrogant' when talking with Kurum.

The follow up decision needs to be 'Fight' and you will earn the achievement.

-Chekhov's Gun:
"Rachel used the machine gun"

After Rachel is reunited with the group (after she reascends the cavern after her fall) and is running from the 'demons' through the temple chamber with the machine gun, choose to fight. The chapter is "Assault"

Succeed the following QTEs and aiming sequences.

-Vision of the Past:
"Rachel witnessed the origin of the creatures."

Rachel must be infected for this to happen. Rachel getting infected isn't story related and can be avoided. When holding off enemies in the assault, have Salim shoot the demon coming for him and not the one attacking Rachel. This will infect Rachel.

Keep Rachel alive up until chapter "Strange Aeons". Inside the Star Chamber, after playing with the central machine she will have a vision as a result of her infection.

-Semper Fi:
"Jason went back for Salim and they both made it to the elevator"

Towards the end of the game choose the heart option 'Forceful' as Jason to go and get Salim. Succeed all QTEs and fight sequences and return with him to the elevator keeping both Jason and Salim alive.

-So You're My Technician:
"Merwin fixed the radio"

Quite a simple achievement although quite missable depending on choices. Merwin just needs to survive until the Chapter "The Signal".

Firstly, after cutting Merwin down near the start of the game, while applying morphine do NOT succeed the third QTE as this will kill him. Stop when Jason says "Your killing him!".

Later when Merwin says to leave him behind you must pick the "Commanding" option. 'I won't leave a man behind!' He will then be present in the aforementioned chapter and obtain the achievement.

-Slayer:
"Salim killed five creatures using his spear"

Across the game you must use Salim's metal stake/spear to kill 5 'demons'. I got this as Salim fought his way to the elevator near the end of the game.

Jason didn't go back for Salim but waited at the elevator for him.

-Ain't Got Time to Bleed:
"Escaped the vault without any lingering injuries"

This only includes any characters surviving at the end of the current playthrough. You must complete the final section with the eclipse without taking any damage (e.g. pass all QTEs).

It is possible other failed QTEs could lead to lingering injury so I recommend trying to pass all combat encounters and QTEs for this achievement.

Nick can find a med kit while he searches for Joey in the caves. This means later in the game he will either patch up himself or someone else if they are wounded. This means you can have at least one injury up to the Star Chamber and have it circumvented by the finding of the medkit.

-The Thing:
"Eric helped Rachel purge her infection"

Firstly, have Salim discover that the creatures are reactive to sun light near the start of the game. Keep him alive. Have Nick and Salim tackle the creature without any failed QTEs and assure him he will be okay.

When he is captive he will tell Eric that the creature will react to the UV wand and Eric will discover the creatures weakness to UV light.

When holding off enemies in the assault, have Salim shoot the demon coming for him and not the one attacking Rachel.

While travelling through the city as Jason and Salim, inspect the prologue character covered in yellow goo.

Later in the game when Rachel has her vision, do not knife the phosphorus round. Choose dialogue options to avoid being shot by Jason.

They will try and save Rachel by putting her in a cocoon. This will fail and Eric will use the UV light on her granting the achievement.

-Heart to Heart:
"Nick killed the ancient warrior with a stake"

The stake is found in the Chapter 'Bloodbath' by examining the corpse with the stake through it's chest in the circular prologue room. Jason will remove the stake. Choose the joking option ("Dismissive") to put it on your rifle and he will give it to Nick.

Later during the Vault Nick must survive, choose 'Advance' while planting the bombs. Pass all the QTEs and Keep Calm moments.

The 'ancient warrior' will grab Nick, complete the following QTE and Nick will save himself with the stake, unlocking the achievement.

-Ghost Signal:
"Eric ignored Nick’s radio signal"

For this achievement, keep Eric and Nick's relationship as low as possible and Eric will ignore Nick's radio after planting the bombs on the cocoons.

Negative options include, not bringing Air Support, not taking the white phosphorus, fighting over Rachel, not saving Nick as Eric in 'The Ancient One' if Rachel is still alive etc. As Nick pass the QTEs while planting the bombs on the vault and complete the advance.

-Old Dog:
"Balathu made two kills with his spear"

During the prologue, kill the woman with the spear while playing as Balathu. (Also choose to 'Fight' later).

For the rest of the playthrough, keep at least Salim, Jason and Nick alive. I would keep every character alive up until the city part for this achievement personally.

Have Nick 'Retreat' when planting the bombs and then as Jason choose 'Forecful' to go rescue Salim. After rescuing Salim fail the next QTE when Balathu throws his spear. This will grant the achievement after Jason dies.

Note: If you have a save file with all characters survived and Balathu killed the woman/stood to fight in the prologue you can just load up the chapter "The Vault" and then follow the method rather than a full playthrough.

Furthermore, it is also possible to get Rachel killed by Balathu's spear in 'The Assault'. If you wish to follow this method, shoot the 'demon' on top of Rachel as Salim. Then pass Rachel's QTEs to save Eric but fail the one to dodge Balathu's Spear.

-Oorah:
"Eric and Nick shared a moment in the elevator"

For this achievement, all characters must die before the elevator ride at the end apart from Eric and Nick. Eric and Nick's relationship must also be positive for this achievement. Not being too aggressive over Rachel will help keep the relationship good.

You can earn this achievement from loading up your save file from the all survived achievement, "Golden Path". Load up chapter "Strange Aeons", knife the phosphorus canister as Rachel to kill her. I would recommend doing this along with "Let Me Have a Go!" achievement as both require positive relationship between Eric and Nick.

Have Nick return when dealing with the cocoons. Then as Jason go back for Salim and then pass Salim's first two combat encounters and then after that fail all the following QTEs and combat encounters to get both Salim and Jason killed.

The achievement will unlock on the elevator after Eric and Nick have their moment.
