Tell Me Why Achievement guide and roadmap

Tell Me Why is out now and this Achievement guide and roadmap will detail what’s required to achieve all Achievements in the game across both Windows PC and Xbox One.


  • Estimated Achievement difficulty: 2/10
  • Approximate amount of time to complete: 10-15 hours
  • Offline Achievements: 30, seemingly worth 1,500 Gamerscore
  • Online Achievements: 0
  • Number of missable Achievements: 0
  • Glitched Achievements: 0
  • Does difficulty affect Achievements? No
  • Minimum playthroughs: 1 full, perhaps 2 full depending on your bond choices


Welcome to Tell Me Why, a narrative told over three separate chapters.

DONTNOD and Microsoft have confirmed with Stevivor that the game’s Achievements will be enabled in batches, timed for the release of each chapter. As such, this guide will be updated with each new chapter. Update: Achievements have been scraped, though it’s unclear how some are unlocked as they weren’t popping as we completed the game. Additionally, Gamerscore allocations aren’t yet known.

A large number of Achievements come through normal progression, though some will require specific acts. We’ll keep Achievement details general below if you’d like to read through each chapter to identify when you’ll need to perform specific actions. To preserve the game’s story, we’d advise playing through a chapter without looking through the details below, though that’s entirely up to you.

You can replay missions if you need a specific Achievement under two circumstances:

  • Isolation mode
  • Restarting from that specific point and replaying everything beyond it

When replaying, we’d advise picking isolation mode, unless you’d like to explore alternate paths in the story. In these sections, you can skip cutscenes to move faster but holding Y.

Tell Me Why Chapter 1 Achievements

  • Rear View Mirror (50GS): Leave Fireweed Residential Center
    • Obtained through normal progression.
  • This is Despicable (50GS): When we say locked, it’s locked
    • You’ll get this from trying to open a locked door multiple times (we got it in three). We got this by trying to continually open the Ronan family barn. (Chapter: A Big Wooden House)
  • One for the Collection (25GS): Found your first Book of Goblins collectible.
    • The first is found under the Ronan’s house. (Chapter: A Big Wooden House)

  • Full confession (50GS): Make Tessa tell you everything she knows.
    • We did this by performing the following in the Vechhi’s store (and not to worry — the Achievement looks to pop far after you’re done speaking with Tessa):

      • Get Tom to put on the music Mary-Ann and Tessa argued to; then, follow your memories
      • Turn on Tessa’s PC and read the email about the Alliance for Traditional Families

  • Hacking 101 (50GS): Hack into the Police Department computer.
    • This password is Salem and is the name of the 2006 Iditarod winner, as per a note in Dee’s locker. Use the reception PC and D. Wilson to enter the password. (Chapter: To Serve And Protect)

  • Bound to a Lie (50GS): Remember a night when the twins agreed to lie.

    • When you go to clean the coffee table in the living room, the moo box is found on its bottom shelf. Keep using it until this pops. (Chapter: Ahoy Goblins!)

  • Guess Who?: Figure out who inspired each Book of Goblin character.
    • You’ll head to the kitchen table and figure this out; the answers are:

    • When in the Archives office of the Police Station, you’ll need to use the computer to check for the “Ronan Children” and “March 1st 2005” tags during your search (they’ll pop up as you uncover more evidence). Doing so will open up a digitised audio recording of the call. Play it! (Chapter: Cold Case)

    • This is obtained by playing the game and making choices that bind the twins (represented by stars joining) rather than stars drifting apart, then playing to the conclusion of the game. Depending on your choices, some on TrueAchievements say you can focus on this from Chapter 3, with others saying you’ll need to restart Chapter 1 or 2 onwards with this in mind. (Chapter: Veni, Vidi, Vecchi or Epilogue)
  • Life Tears Us Apart: Complete the story with the twin’s bond weakened.
    • This is obtained by playing the game and making choices that drive the twins apart (represented by stars drifting apart) rather than stars joining, then playing to the conclusion of the game.

(Chapter: Veni, Vidi, Vecchi or Epilogue)

    • This unlocks when you finish the game without a strong bond with your sister.

(Chapter: Epilogue)
  • Lock-Up And Go: Lock-up and leave the Ronan House with Tyler.
    • This unlocks when you finish the game with a strong bond with your sister. (Chapter: Epilogue)
