CSGO (Legacy - 2023)

CSGO:Legacy, or CSGO (2023) is the latest version of Counter-Strike: Global Offensive that was officially released by VALVe in 2023 before Counter-Strike 2 took over. CSGO:Legacy contains several gamemodes that weren't ported over CS2 yet, such as Danger Zone or the Holiday modes.

By default, CSGO:Legacy does not keep up with the player inventory, but there is a way to correct this. Look at the bottom of the page for more info.

Requirements

• A Steam Account
• Counter-Strike 2 installed
• About 80GB available

Installation (Windows)

1. Right click on Counter-Strike 2 on Steam, then select Properties (you can also click on the cog at the right of the screen when selecting Counter-Strike 2)

2. Go to the Betas tab, and select csgo_legacy - Legacy Version of CS:GO.

The game will download the files that are required for CS:GO. Once downloaded, you can select it when starting Counter-Strike 2.

Installation (Steam Deck)

Similarly to Windows, we will install the csgo_legacy branch for Counter-Strike 2. However, we will have to do some extra steps to allow our system to run CSGO.

1. Go to the properties of Counter-Strike 2.
2. Go to the Betas tab, and select csgo_legacy - Legacy Version of CS:GO.
3. If not already, you will have to switch to Desktop Mode.
4. Add a non-steam game

/home/deck/.steam/steam/steamapps/common/Counter-Strike Global Offensive/csgo.sh

5. In the launch options, add the following:

-steam -novid -secure -novid

6. In the compatibility options, set it to Steam Linux Runtime 1.0 (scout)

Enabling back your Inventory

Please open steam.inf within the CSGO folder:

Windows:

<YOUR STEAMAPPS FOLDER>\common\Counter-Strike Global Offensive\csgo\steam.inf

Steam Deck / Linux:

~/.steam/steam/steamapps/common/Counter-Strike Global Offensive/csgo/steam.inf

Find the ClientVersion token, and modify the value to 2000426.

When starting the game, you should be able to see a little more in the main menu, as well as accessing to your inventory, and the server browser.
