Individual prerelease counts require verified game access. GaugeDB can record a count if Steam publishes one in its public chart, or when collection becomes available after release.
No Steam player count has been recorded for OSO yet.
Concurrent Steam players, not daily or monthly active users. Console and other launchers are excluded. Peaks cover GaugeDB’s recorded history.
Welcome to OSO, where you get to add hazards to the map whenever you die! Throw down a fan and launch your friends into the void, or kick them into a well-placed spike to get your revenge.
