GameDiscoverCo: Counter-Strike has been downloaded by more than 318 million people
Combined with CS: GO numbers.
The information comes from a GameDiscoverCo study on the Steam Deck audience. It is an interesting piece of research that I wrote about a couple of months ago. The data is valid as of October 2025.
Counter-Strike 2 is owned by 318 million Steam users. It is the most popular game on the platform by a wide margin, but you should remember that Counter-Strike 2 replaced Counter-Strike: Global Offensive.
Dota 2 ranks second with 222.6 million users, PUBG is third with 169.6 million, Team Fortress 2 is fourth with 100.5 million users, and Apex Legends is fifth with 70 million users.
PAYDAY 2 is the highest-ranking paid game on the list (9th place). Interestingly, the project surpassed even the combined Call of Duty distribution on Steam in terms of copies sold (10th place). However, the data was collected before the release of Call of Duty: Black Ops 7, so the positions have most likely changed since then.
