Half-Life 2 reached over 60,000 concurrent players on Steam over the weekend following its 20th anniversary celebrations.
At the time of writing, its current peak is 64,085 concurrent players. According to Steam DB, this is the game's highest peak since the site began tracking player counts in 2008.
The game's previous peak was 16,101 concurrent players in August 2021.
The increase in players comes after Valve released a surprise update that combines the base game with its episodic sequels, Steam Workshop support and in-game commentary.
A two-hour documentary was released in tandem, celebrating the game's milestone and lasting impact. Valve also made Half-Life 2 free on Steam for a limited time.
