Global unlock shares from Steam’s own achievement percentages, read on 28 Oct 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. How this is computed. Data by SteamPeaks.com.
