All That Remains: Complete Walkthrough Guide

16. Enter the War Room. Take a photo of the map in middle of the room. Also, take a photo of the blackboard (The Big Board). There are some shapes as part of equations.



17. Leave the room. Let’s use the equations to solve the puzzle above the crate. So:

Circle x Diamond = -2
Circle – Diamond = -3


Circle = -2
Diamond = 1

Square x Triangle = -6
Square – Triangle = -5


Square = -3
Triangle = 2

Take the screwdriver and glass plate.



18. Go back. There’s a crate near the bathroom door. Look behind it for a lock. Use the clue from the other crate to figure out how to solve the puzzle. Go through the door.




19. Look at the abacus and move the wooden beads so they’re all matched up with the black lines. Take a photo of it. Also, take a photo of the pipes on the wall. We’ll use it soon.



20. Go all the way back to where you found the small phone box. Tap on the door to the left and use the arrow buttons to copy the pattern from the abacus and unlock the door. Go through.



21. Turn off the radio for now if you want. Take the wooden piece next to it. Open the drawer below it and take the pressure gauge.


22. Use the screwdriver to open the grate and take the piece of advert from inside.


23. Climb up to the top bunk bed to see a record. It shows he phone box being used as a prism. It’s a clue!



24. While we’re here, let’s solve the alphabet puzzle. You need to use the pipes together with the note on the fridge. I recommend going back to the pipes room to work on it. Pretend you’re a rat running through the pipes. Start at a letter and every time you hit a yellow junction, you turn right or left depending on what the fridge note says. If you’re supposed to go left (or right) at a specific junction and there is no left there, just go straight and turn left at the next opportunity. If you run out of directions but still hit more junctions, just continue going straight. When a pipe disappears into the wall, it emerges on the other side. Don’t forget that!

Here’s an example with A going LRLR:


Don’t forget that you can draw on the photo in the game! Here’s a copy of the fridge note if you want to look at it while doing so:


Alternatively, you can open a smaller version of the fridge note in-game and then open a full-screen version of the pipes. You can then draw on the pipes and look at the fridge note all on the same screen, like so:




If you don’t want to draw on it and rather just mess around outside the game, here’s a clean version of the pipes with the fridge note attached:


You can also try my video which walks you through each letter:

So this is what you get in the end:

A: J
B: C
C: D
D: B
E: H
F: G
G: A
H: E
I: H
J: F

Now, just point each letter to the letter it led to in the pipes puzzle. It should open and you can take the two weights.



25. Use the wrench to take the ladder.


26. Plug in the night light by the bottom bed so you can see a loose brick. Pull out the brick and take the crowbar and other half of the advert.


27. Combine the two pieces of the advert in your inventory. The phone number on it is 555-38-924.


28. Take the night light back. The book on the bed is missing half the page so we’ll come back to that later.


29. Look at the poster for New York above the piano. It says THERE’S MORE TO THE BIG APPLE THAN MEETS THE EYE.


30. Look at the piano keys and take a photo of the lettered keys. You can surmise that the missing ones would be BEG, as in BEG FOR LIGHT. That means the keys go ABCDEFG.

        I see AppUnwrapper has included a link to a video about dialling a rotary phone. I had a momentary problem with dialling. On the game’s phone, one dials clockwise. In the real world, rotary dialling was counter-clockwise in the USA.

        1. Susb8383

          Not true. I live in the U.S. and we had a rotary phone way past when most people had buttons. You turn the dial clockwise as well.

          Thanks for the walk through. I never did figure out the Moscow time but just changed the hands until it worked since I had the other three. What was the point of the Jules Verne book? Maybe that will come up in Part 2.

          1. susb8383

            Yes, I know. But he says in the comment that rotary dial is counter-clockwise in the U.S., which isn’t true.

            1. CatReader

              I retract my statement regarding rotary dialing in the U.S.: it was clearly clockwise, just as Susb8383 stated. What was different from the phone in the bunker is that our phones placed the 1 closest to the dial stop and 0 farthest away. I definitely remember the relative distances the dial had to rotate. In fact, when faced with the phone in the puzzle, I initially tried to dial it in reverse direction.

              Susb8383, for the Moscow time, the clue is on the bottle of vodka. Read the label carefully.

              1. Beansie

                Yes Catreader you are right! The rotary dial phones (in the U.K. as well as US and Australia) started with the number 1 at the top of the dial ie the number requiring the least amount of dialling! As the emergency number in the U.K. was – and still is – 999 I remember there was always a debate about the length of time it took to dial 999 because of the extra time it took the dial to purr back round, before you could dial the next number. I love the fact that I’m so old I can remember this and most of you are so young that you need a video of how to use a rotary dial! Lol ? Hope you managed to work out the radio, or should that be wireless!

    How do you get the ladder down in step 40? Everytime I try it says “I can’t reach. I need something to help.”

  2. The Jake

    On Android, at end of game, when you open door, the final video crashes. Well, it is called glitch games. Hehe. Reported bug.

  3. mn3m0n1c

    Is there anything that I need to do in order for the phone to work?
    I have the advert.
    I dial the the number by pulling the rotary wheel around to the finger stop.
    Nothing happens.
    There is no dial tone, no ringing, no answer, no drawer opening. No bloody key.
    I have the most recent update although I tried before the update as well.
    I watched the walkthrough video but did not see anything.
    Short of deleting the and reinstalling the app, any ides

  4. Beansie

    I got to the very end, pulled the lever and went to the locked door and the final lock is still locked! Is that how it’s supposed to end?

  5. P.A.

    “They were born 1 year and 5 days apart. So that means Cam’s 21st birthday was either on 9/9/1981, or 9/19/1983.” You don’t have to try two dates. Campbell has already mentioned having to babysit his sister so it is clear he is the older sibling.

  6. Steven

    I put the floppy disk in and there are no options to select ‘1’ or ‘4’ – just the same enter password to login page that was there before. ‘BKR-GH00942337’ doesn’t work at that point. Great walkthrough – I would never completed the pipes puzzle without it.

  7. Wendy

    I can’t get the tile to open to show me the security box. I’ve done the patterns, pressed the button but nothing happens. Not sure what I am missing.
