Playtime is that of people who reviewed, from the 300 reviews SteamPeaks sampled for Left 4 Dead 2: 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.
Viewers are Twitch’s counts for the game’s category, sampled by SteamPeaks every 10 minutes; players are SteamPeaks’ own counts, averaged onto the same bins. The correlation is the strongest over lags from six hours before to six hours after; a lift compares the six hours after a spike with the same six hours a week earlier and is an estimate, shown beside its baseline. Correlation is not causation: the figures say how closely the two series move together, not that one caused the other. Verdict from the daily job, run 6 Sep 2026, 15:26 UTC, over 4 days of both series. How this is computed. Data by SteamPeaks.com.
Viewer counts from Twitch.
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. How this is computed. Data by SteamPeaks.com.
The band is the 25th to 75th percentile share of the launch level among zombies games at each month since launch, with their median as the line; a game joins a curve after 6 months of averages. Recomputed weekly, last on 5 Sep 2026. How this is computed. Data by SteamPeaks.com.
