The weekend after launch is often when games hit their all-time peak Steam concurrents (at least until a big sale or special update), and Borderlands 4 managed to hit 304,398 on Sunday, according to SteamDB's record keeping.
It's an impressive achievement for Gearbox's $70 co-op shooter, but if it puts Borderlands 4 somewhere in the stratosphere, then Hollow Knight: Silksong must be mingling with the aurora borealis, having hit 587,150 concurrent Steam players on the Saturday after it launched.
