How to read a Steam player chart
Console players can choose their own platform, consoles only, or all platforms for matchmaking. A Steam-wide count therefore cannot tell you exactly how many opponents are available in your selected raid and platform pool. For a raid without other player squads, read the PvE guide.
- Open the chart for the base game, App ID 2887580, and check which application the figures describe.
- Read concurrent players as the number online on Steam at that time, not total owners or players across all platforms.
- Record the exact date, time, timezone, and source.
- Separate the current value, 24-hour peak, and historical peak.
- Keep Gaijin and console coverage listed as unavailable unless an official source publishes it.
