Is the Combat Skirmish client free?

Yes. The client is free, with no account required and no ads anywhere in it.

Do I need to download the client to play?

No. The same game runs in any modern browser at combatskirmish.net with nothing to install. The client is for players who prefer a normal app window: true fullscreen, your monitor’s full refresh rate, and no ads.

Does the client include Counter-Strike game files?

No. The installer is the app only. It streams the game files it needs from the same servers as the website and keeps them cached, so it stays small and always matches the live game.

How does the client update?

It checks for a new version every time it starts, verifies the update’s signature, and installs it. You never need to download it again by hand.

Is there a Mac or iPhone version?

Not yet — builds exist for Windows, Linux, Android. On a Mac, iPhone or iPad, play in the browser instead: it is the same game.

How do I check that my download is genuine?

Compare the file’s SHA-256 checksum with the one listed next to it on this page, or with the SHA256SUMS file published with each release.

Why use the client instead of the browser?

The game is identical — the client loads the same live game the website runs. What changes is the window around it. On Windows and Linux the client gives you:

No ads and no website copy around the game, anywhere.
Real fullscreen that opens with F11 or Alt+Enter, not a browser tab stretched to fill the screen.
Your monitor’s full refresh rate instead of whatever the browser allows.
No throttling when you alt-tab mid-match — browsers slow background tabs down, the client does not.
Sound and voice chat from the first second: menu music plays without a click, and the microphone is allowed once instead of prompting mid-match.
Server links that open the game: a cs16:// link joins that server directly.
Steam-authenticated servers: servers that require a Steam login accept you through your own Steam client running on the same PC. Your Steam credentials never leave your machine.
Automatic, signed updates checked every time it starts.

The Android app is the same game as a phone app, with touch controls, and it updates itself the same way.

Screenshots

What the download contains

The installer is only the app — a small native window around the live game. It does not bundle Counter-Strike: the client streams the maps, models and sounds it needs from our servers, the same way the website does, and caches them so the next start is fast. That keeps the download to a few megabytes on Windows and means the client never falls out of step with the game.

What’s new in 1.41.1 (build 4)

Released October 12, 2026. Every release, with checksums.

Connection fix

Improved

During updates the site now shows a short maintenance notice in your language and reloads by itself, instead of an error page
The key bindings on the loading screen fit small windows and phones
The co-op map list shows when a hidden filter is narrowing the results
When playing inside another site, turning the view past the top or bottom edge is now highlighted too

Fixed

After the last update, joining a server could sit on "Connecting…" forever. Connections go through again, and if a server stops answering while you join, the game now falls back to another way in instead of waiting
Co-op rooms hosted from a background tab could show up in the room list before they were ready to join
