24 games like Counter-Strike: Source (2026)
Every game below overlaps with Counter-Strike: Source on things players said about it rather than on our opinion of what feels alike. Each entry shows what it matched on, so you can throw out the ones matching on the part you did not care about.
The short version
- Closest match: Counter-Strike: Global Offensive, which made by the same studio, Valve.
- Counter-Strike: Source is tagged Shooter, FPS, Action, Multiplayer, Team-Based, First-Person, Competitive, Tactical by Steam players. Those tags are what the matching runs on.
- 24 games qualify, each with at least fifty player reviews behind its sentiment figure.
- 5 are free to download, so you can test the resemblance yourself at no cost.
- 6 are from the same studio: Counter-Strike: Global Offensive, Counter-Strike, Counter-Strike: Condition Zero, Day of Defeat, Left 4 Dead, Day of Defeat: Source.
How these were matched
Steam tags carry the most weight, because players apply them and they describe how a game feels rather than how it was filed. Souls-like, Atmospheric and Cozy exist as tags and as nothing else, which is exactly the vocabulary this question needs. Formal genres count for less, themes and a shared studio for more.
Tags carried by more than a third of the catalogue are thrown out before matching. Nearly everything is tagged Singleplayer, so matching on it is matching on nothing. That cutoff is computed from the catalogue rather than fixed, so it moves as the catalogue grows.

Common questions
What game is most like Counter-Strike: Source?
Counter-Strike: Global Offensive, on the evidence we have. It made by the same studio, Valve. That is a statement about overlap, not a promise you will like it as much: two games can share every tag and still feel different to play.
How is "similar to Counter-Strike: Source" decided?
By overlap on the tags Steam players applied to each game, the formal genres, the themes both sit in, and whether the same studio made them. Tags carry the most weight because players write them, so they describe how a game feels rather than how it was filed. Tags carried by more than a third of the catalogue are ignored: matching on "Singleplayer" is matching on nothing. Every entry below shows exactly what it matched on.
Are these ranked by quality?
No. They are ordered by how much they overlap with Counter-Strike: Source. Where two games overlap equally, the better received one goes first, but that only moves a game a place or two. Each entry shows its own player sentiment so you can weigh that separately.
What else did the makers of Counter-Strike: Source do?
Counter-Strike: Global Offensive, Counter-Strike, Counter-Strike: Condition Zero, Day of Defeat, Left 4 Dead, Day of Defeat: Source are also from Valve, and appear in the list below for that reason as well as on tag overlap.
Do you get paid for these recommendations?
No. The order is computed from tag and genre overlap and nothing else. No placement here can be bought, and a game appearing high on this page is a statement about resemblance rather than an endorsement.
