-Hope You Enjoyed Your Stay:
"Completed the Solo Story"


This achievement is awarded for completing the full game on Solo Story mode (singleplayer). There is no achievement for Shared Story (online co-op) or Movie Night (couch co-op) this time.

Note: If you have this achievement not unlock, reload the final chapter via chapter select into a new slot and play it again.

-Murder Castle:
"Completed the prologue"


Awarded for simply completing the prologue in any mode type on your first playthrough.

-Until Death Do Us Part 2:
"Jeff and Marie watched each other die"


This achievement is available in the prologue. When playing as Marie in the lobby, pick up the left bottle and she will take a bath later. Investigate the man in the bathroom when prompted and make sure all QTEs and heart beat sections are cleared successfully in the entirety of the prologue. Jeff will get gassed and watch Marie bleed out from her wounds.

-Happy Ending:
"Everyone survived"


This achievement can be obtained by following these guidelines and choices:

• Succeed in all your QTEs, balancing, stay calm mini-games and combat encounters.
  
  
• Take and use the inhaler as Erin whenever prompted to. (Do NOT attack Du'Met in the dark room).
  
  
• As Erin hide in the cupboard when prompted by Jamie over the microphone (in Silver Ash Institute). Do NOT run.
  
  
• When Charlie is in the furnace, choose the grate option twice, not the door.
  
  
• In the suffocation chamber, Jamie must choose to kill Kate. (Mark will save her automatically after this).
  
  
• Keep the screwdriver as Jamie and in the glass trap don't press the button OR give the screwdriver to Kate and push the button.
  
  
• Save Jamie on the rooftop from Du'Met, do not run.
  
  
• When you are being chased into a building after Du'Met has picked up an axe, do not barricade the door and choose to run.
  
  
• Believe Charlie is innocent as Mark.
  
  
• Survive the boat attack by making sure each character passes QTEs and they jump off the boat when possible.

-Unhappy Ending:
"No-one survived"


Easy way to do this is to load the everyone lives save via chapter select into a new slot from the final chapter 'Lake'. Fail everyone's QTEs and attack when possible and they will all die. Obviously there are other methods but this is a quick one.

See achievement 'The Cycle Continues' below if you wish to combine these two.

-The Cycle Continues:
"Mark agreed to Du'Met's proposal"


This achievement can be unlocked by following the below steps:

• Let Erin die as early as possible.
  
• Let Charlie die in the furnace by trying to open the door.
  
• Don't kill Kate in the glass trap.
  
• Let Jamie die in the glass trap or on the rooftop. (Only keep Mark and Kate alive).
  
• Choose to "Help Mark" in the Lighthouse as Kate (unlocks 'Award Worthy').
  
• Agree to Du'Met's plan and continue with the unique ending by agreeing to lure new people in.

-Happier Ending:
"The dog made it off the island alive"


Assuming all characters are alive, Jamie and Kate will come across a dog in an abandoned house towards the end of the game. Here Jamie must tell Kate to 'Hide' and then not kill the dog when prompted. It may be required that Kate learned the name of the dog in the Chapter: 'Morellos'.
Keep him alive to the end of the game and the achievement is yours.

-Ignited:
"Jamie chose to save Erin in the suffocation chamber"


Choose the option 'Kill Kate' during the suffocation chamber section, thus saving Erin for this achievement. Erin must have survived the killer in the Silver Ash Institute and not attacked the killer in the dark room. Kate will survive this so don't worry!

-Phoenix:
"Charlie survived the furnace"


When Charlie is locked inside the furnace pick the 'Lift Grate' option twice. He will lift the grate and hide under the flames and later in the game he will be alive and you will earn the achievement at that point, not before.

-Shattering Expectations:
"Kate and Jamie both escaped the glass trap"


If Jamie and Kate are alive after failing to trap Du'Met then they will end up in a glass trap. If Jamie has the screw driver do not hit the button and the trap will not kill her. Alternatively, if Kate has the screwdriver, hit the button and it will not kill her. Doing so will award the achievement after speaking to the Curator.

-Extinguished:
"Jamie chose to sacrifice herself in the glass trap"


Jamie must have given the screwdriver to Kate before attempting to trap Du'Met and then must not press the button in the glass trap, letting Kate live and killing herself. She must die for this achievement.

-Collector:
"Found all of the Secrets"


Secrets are interactable documents, books and items in the environment. Sometimes they require to be rotated and flipped through. Not all items or papers are secrets.

The Curator's Cut (or Shared story) is required for 2 secrets in the chapter 'Party' (Erin must be alive as well - find the candlestick as Kate in the Curator's Cut to save Erin in the Dark room).

-Say Cheese!:
"Took a photo of each crew member"


When in control of Mark you can use his camera tool to take photos. Take at least one photo of each member of the team. I.e. Kate, Erin, Charlie and Jamie.

Kate has a few opportunities for photos starting from 'Scouting'. Erin and Charlie can be photographed at the Lighthouse if they are still alive. I am unsure how to possibly photograph Jamie though, if you know how let me know.

Curator's Cut method: In the Curator's Cut you can access Mark's camera before heading across on the ferry (chapter: 'Opportunity') and the entire group is one place making this achievement trivial. Curator's cut is a pre-order bonus but becomes available to everyone in about a months time.

-Handy:
"Obtained all of the inventory items"


Curator's Cut required.

You need to find every possible item characters will put in their inventory. This includes keys, flashlights, camera lens etc. The items are carried across save files in regard to the achievement progress, not the physical items.
All keys are story related apart from the shed key found in 'Homestead' after crawling under a log. It is behind the shed.

Here is a list of the "missable" items assuming you keep characters alive (although 1 item needs Charlie to die).

• Prologue, Bath soap + Powder - These two items are mutually exclusive in the prologue theatrical cut.
  
• Workshop, Camera lens one - Can be found up high on a shelf in the second room. Use Mark's stick to knock it down.
  
• Workshop, Screw bit - Mark will attach this to his stick. Found on the workbench after the third hide sequence.
  
• Camera lens two, Cliffside (Charlie dead) - Found in the drawer in the ferry station building near the lake.
  
• Homestead, Flashlight + shed key - The shed key is behind the shed. Inside the shed near the body is a flashlight.
  
• Lake, Spray - Tell Mark to pick up the cops gun. The lighthouse must be activated for this.

Curator's Cut:

• Prologue, Necklace + Pocket Watch - Mutually exclusive items that can be picked up.
  
• Party, Lounge Key - Erin must be alive, see "Collector" achievement. You will need this chapter to get two secrets as well.

-Award Worthy:
"Kate fell for Du'Met's impersonation"


This achievements is covered in "The Cycle Continues", see Ending Achievements. Kate must 'Help Mark' in the lighthouse - Charlie, Erin and Jamie must be dead.

-Guilty:
"The crew didn't trust Charlie and he paid the price"


During the chapter 'Silver Ash' find the recording as Erin behind the surgical curtain of Charlie having a conversation. Keep all characters alive and when Mark, Charlie and Erin regroup at the lighthouse, don't trust Charlie as Mark. He will tie him to the fence. Continue on and eventually it will be revealed that Du'Met has killed Charlie and the achievement will unlock then.

-Lend Me A Hand?:
"Charlie's hand was crushed"


During the chapter 'Wall' fail the button mash prompt during the closing wall and Charlies hand will get crushed unlocking the achievement.

-Can You Pet The Dog?:
"Yes, you can pet the dog"


During the Chapter 'Cliffside' Mark will come across a dog if Charlie is dead. When he raises the rock do NOT throw it at the dog and he will pet it instead and the achievement will unlock.

-0451:
"Jamie reset the fuse box"


During the chapter 'Staff Only' Jamie will be challenged with turning on the power. Find the locked keypad door and type in the code 0451 to unlock it and then solve the fuse box puzzle for the achievement.


-Shocking:
"Fixed all of the fuse boxes"


There are 3 fuse boxes that can be repaired throughout the game. The first is to power up the tram car while climbing up the island, the second is tied with 0451 above, and the third is after being separated from the group, to open a wall (after the chapter following Mark in the Workshop). Complete them all for the achievement.

-Sparks:
"Jamie and Erin kissed"


There will be a point near the start of the game (Chapter: Guests) where Erin will drop her lipstick under the bed in a room with Jamie. As Jamie pick all the romantic, flirtatious and kind options possible and as Erin move in for the kiss when prompted. They will kiss and the achievement will unlock.

-Toasty:
"Charlie maintained control during dinner"


During the dinner scene (chapter of same name), you will play as Charlie. Make sure to pick all dialogue options that commend your team and do not get freaked out over Du'Met's disappearance. Perform a nice toast to them.

-Rekindled:
"Kate and Mark rekindled their relationship"


In the chapter 'Scouting' pick the dialogue options below as Mark:
EARNEST
REASSURING
HESITANT
SERIOUS

Then continue as normal until the next dialogue option and pick:
ENCOURAGING

Then in the next set (about Charlie) pick:
EMPATHETIC

SURPRISED
APPREHENSIVE
KISS

-Hark!:
"Mark got the lighthouse working"


Mark must survive up to the chapter 'Lighthouse' and then must repair the lighthouse by climbing to the top, pulling the switch on the outside around the shimmy ledge and then pressing the red button.
