๐ Scarlet Idol Achievements
This Scarlet Idol achievements guide is designed as a clean reference page for players who want to track chapter completion, hidden achievements, and likely replay routes without relying on the default Steam layout.
At the moment, Scarlet Idol has 11 known Steam achievements: 7 progression-style milestones and 4 hidden achievements that likely relate to endings, route outcomes, or late-game decision states.
Use this page during a second run or as a post-chapter checklist. If you are still in your first playthrough, it is usually better to stay on the chapter walkthrough pages unless you are specifically trying to avoid missing a milestone.

For most players, the cleanest achievement strategy is simple: finish a natural first run, then return with notes. Scarlet Idol's story progression achievements should unlock as you move chapter by chapter, while the hidden achievements are more likely to depend on route conditions, ending states, or choices that are easier to manage once you already understand the structure of the game.
If you want broader progression help before targeting hidden outcomes, go back to the Beginner's Guide, the Prologue Walkthrough, or the Chapter 1 Old House Walkthrough.
Scarlet Idol currently has 11 Steam achievements in total, including 7 story progression achievements and 4 hidden achievements.
Usually no. A first run is better as a natural co-op experience. Achievement cleanup makes more sense on a second run, especially if hidden achievements relate to endings or route states.
Take notes near chapter endings, route splits, and major decisions. If possible, coordinate with your co-op partner so both of you remember which outcome conditions were already seen.
