Underground Blossom 100% Achievements Guide

All achievements in the game.

Underground Blossom 100% Achievements Guide

All chapters except for the last one includes four achievements numbered 1, 2, 3, 4.

  1. Story related. Awarded for finishing a chapter
  2. Story related. Awarded mid-chapter for an action pushing the progress forward.
  3. Missable. Awarded for finding a random action, usually related to clicking an object multiple times.
  4. Missable. Available after completing the game.

The achievements are presented in chronological order although there might be slight differences between earning “2” and “3” achievements depending on your choices in the game. The final chapter “Underground” is much more flexible but no achievement is missable in it.

Since the last achievement in each chapter require completing the game they’re in a separate section of this guide so the achievements can be kept in chronological order. I’ve ordered them by chapter, but they can be earned in any order and aren’t missable.

The final chapter Underground is available only after collecting all seven cubes which means obtaining all seven achievements labelled “4”. Achievements in this chapter are a bit more involved which is why their descriptions are longer.

Underground Blossom - 100% AchievementsYour memories are safe with us
Underground – 6

Enter code 23 in the tape machine and pick up tape labelled “Vendome_Ba”. Go to the TV and watch the tape. Step back from the TV.

This achievement is part of the same ARG mentioned above. It involves trailer of “The Past Within” for Nintendo Switch and the game “The Past Within” itself. The trailer shows two codes 3Y1 and XZ2 which can be entered in The Past Within. The exact solution is described in the ARG document mentioned above. Basically Vendome Barroso is an anagram of Rose Vanderboom and that’s how we get “Vendome_Ba” (or “”Vendome_Barro” when the tape is in the TV).
