How these estimates are made

Atlas Reactor

We estimate that about 430 people play Atlas Reactor on a typical day (most likely between 99 and 1,300), based on data from Nov 9, 2026. Around 190,000 accounts (between 140,000 and 240,000) have played it at some point. Atlas Reactor is on Steam, but Steam covers only part of its players, so the estimate also draws on the size of its Discord, Reddit, Twitch, YouTube and app-store communities. Confidence: low — a community-size model, not a measurement.

Tannenberg

We estimate that about 810 people play Tannenberg on a typical day (most likely between 190 and 2,400), based on data from Nov 9, 2026. Around 250,000 accounts (between 200,000 and 330,000) have played it at some point. Tannenberg is on Steam, but Steam covers only part of its players, so the estimate also draws on the size of its Discord, Reddit, Twitch, YouTube and app-store communities. Confidence: medium — Steam covers part of the player base, or several community signals agree.
