CSGO (Legacy - 2023)

Requirements

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

Installation (Windows)

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)

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 (Linux 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.

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

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

In the launch options, add the following:

-steam -novid -secure -novid

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

Enabling your Inventory

This step is optional but HIGHLY recommended!

If you do not enable them, you will receive errors in joining some specific community servers (such as snowball mode)
