Automatic Update via Steam:
If you already own CS:GO, CS2 will automatically update in your Steam library. Ensure your Steam client is set to update games automatically or manually check for updates by right-clicking on CS:GO in your library, selecting "Properties," and then "Updates" to verify the game is set to update.
The update process will replace CS:GO with CS2, so all your skins and items will carry over to the new game.
Manual Update or Fresh Install:
If you encounter issues with the automatic update, you can uninstall CS:GO from your Steam library and then install CS2 directly from the Steam store page where CS:GO used to be, now listed as Counter-Strike 2.
