Global unlock shares from Steam’s own achievement percentages, read on 6 Sep 2026, ordered most common first. The finish rules (beat the game, completed the story, final boss, credits, epilogue and their variants) matched no name or description, so the funnel has no finish step rather than a guessed one. Shares are of players who have the game on their account, as Steam counts them. . Data by SteamPeaks.com.
Playtime is that of people who reviewed, from the 599 reviews SteamPeaks sampled for The Callisto Protocol: their total hours when the sample was read, and the hours they had when writing (the refund-window share). Reviewers have usually played more than owners who never wrote a review. Recomputed daily. How this is computed. Data by SteamPeaks.com.
Quieter than 97% of horror games at month 44.
Monthly averages from the imported archive and SteamPeaks’ own daily rollups after it, Dec 2022 to Aug 2026, each month divided by the launch level (2,229). The band is the 25th to 75th percentile of horror games at each month since launch (54 games at launch); the half-life is the first month under half, counting from the month the launch level was set. The projection is the cohort’s band for the next twelve months scaled to this game’s share now: what horror games usually do next, not a forecast of this game, so it is drawn as a band and labelled an estimate. Recomputed weekly, last on 5 Sep 2026. How this is computed. Data by SteamPeaks.com.
