How to Play CS:GO After CS2 on Steam (CS:GO Legacy Guide)
Introduction
Even after Counter-Strike 2 replaced CS:GO, it is still possible to play CS:GO on Steam through the official CS:GO Legacy build. In 2026, many players still look for ways to install CS:GO after CS2 for offline play, LAN matches, workshop maps, and older community servers.
This guide explains how to access CS:GO Legacy, how it works after CS2, and what limitations you should expect compared to the fully supported Counter-Strike 2 version.
Why You Can Still Play CS:GO After CS2
On Spetember 27, 2023, Counter-Strike 2 replaced CS:GO as the main version of the game, but Valve did not erase CS:GO from Steam entirely. Instead, they preserved the final CS:GO Legacy build as an official branch that can still be installed and launched through the Counter-Strike app. That is the main reason players can still play CS:GO after CS2.
This means CS:GO still exists as a frozen legacy version rather than a fully supported live game. It keeps the original engine, maps, and core gameplay, but it no longer receives normal feature development as the active Counter-Strike title. So in 2026, the only official way to play CS:GO is through the CS:GO Legacy build on Steam.
How to Install CS:GO Legacy on Steam
CS:GO is no longer installed as a separate game. The only way to access it today is through the CS:GO Legacy build.
CS:GO Legacy - What It Is
CS:GO Legacy is a preserved, non-updated version of CS:GO kept by Valve after CS2 replaced it. It runs on the original CS:GO engine (Source) and gameplay, but no longer receives updates or official matchmaking support. You can think of it as a frozen snapshot - similar to loading an old save in a game - of the final CS:GO build that can still be installed and launched through Steam.
Activate CS:GO Legacy in Steam
- Open Steam and go to your Library.
- Find Counter-Strike 2, right-click it, and select Properties.
- Open the Betas tab and under Beta Participation, select:
csgo_legacy – Legacy Version of CS:GO. - Wait for Steam to download the required files (around 13 GB).
- Click Play in Steam and choose the Play Legacy Version of CS:GO option to launch the game.
How CS:GO Works After CS2
After installing CS:GO Legacy, the game works the same way classic CS:GO did, but without access to Valve’s official matchmaking. You can still use it for offline play, practice, and compatible multiplayer setups.
Offline Play
CS:GO Legacy fully supports offline play. You can start local matches, play with bots, load custom maps, and test configs, binds, and settings.
LAN and Community Servers
LAN functionality works the same way it did before CS2. You can host or join local network games without using online matchmaking, which makes CS:GO Legacy suitable for private matches or local setups.
Many community servers have already moved to CS2, but some still run CS:GO-compatible builds and can be accessed using CS:GO Legacy.
To connect to LAN or community servers, you need the server’s IP address and port. Use the in-game console and the command: connect IP:Port
Common Issues and Fixes
Below are the most common technical issues CS:GO Legacy users run into and how to fix them using standard Steam tools.
CS:GO Legacy Does Not Launch or Closes After Launch
If the game fails to start or closes immediately after launch, the most common cause is corrupted or incomplete files after switching to the Legacy branch.
Fix: Verify the game files in Steam and remove any launch options.
Open Steam -> Library, right-click Counter-Strike 2, select Properties -> Installed Files -> Verify integrity of game files. Wait for the process to finish, then restart the game.
Black Screen or Invisible Window
In some cases, CS:GO Legacy launches in the background with sound playing but no visible window. This is usually caused by resolution conflicts or third-party overlay software.
Fix: Disable overlays such as Discord, GeForce Experience, or MSI Afterburner, and remove any launch options. Restart the game after making these changes.
Server Version Mismatch
When connecting to multiplayer servers, you may see version mismatch errors. This happens when the server is running a different CS:GO build or has already migrated to CS2.
Fix: There is no client-side fix. Make sure the server is actually running a CS:GO-compatible build, then contact the server administrator for details.
Conclusion
Counter-Strike 2 is now the main platform for CS, but the CS:GO Legacy version is still useful for players who need the classic client. It works for offline play, LAN, and dedicated servers, even though official matchmaking is no longer available. Everything else has moved on to CS2, which is now the actively supported version.
