Authoring Tools

The Counter-Strike: Global Offensive Authoring Tools, also known as the Counter-Strike: Global Offensive SDK, is a set of software utilities that allow you to create your own levels, and other gameplay elements. They include versions of Source SDK tools that have been updated to work with the CS:GO version of the Source Engine.

Availability

The SDK is available on Steam to Counter-Strike: Global Offensive or Counter-Strike 2 owners with Prime Status running Windows. The Prime Status has to be bought through CS:GO (prior to Oct 2023), CS2 or Steam, or by having bought CS:GO before it became free to play (Dec 6, 2018). Players who have been awarded Prime from reaching rank 21 or higher are not given the SDK.

As of the CS:GO update in Oct 2023, under the csgo_legacy branch, the option to purchase Prime Status directly from CS:GO has been removed, but it can still be purchased through CS2 or via its Steam Store page.

After the release of Counter-Strike 2, you are still able to download the CS:GO SDK, even if you already owned the free prime upgrade.

Downloading and Installation

1. Open the Steam window.

What's included?
