The exact number, which stands at 28,230,661, is the first time in history that Steam has reached over 28 million concurrent players - after narrowly missing out earlier this month.
In March 2020, the platform celebrated a landmark milestone as over 20 million different players were seen to be using the service.
In February of last year, IGN reported that the service had seen over 26.4 million players, while further records were later set over Thanksgiving weekend, when over 27.3 million players were playing at one time.
