Becoming A Steamworks Developer

This article is for those developers that have gotten their game through Greenlight, or that have been given a publishing deal with Valve to post their game on Steam. If you are not already a Steamworks Partner, then you probably have to find a publisher that is, or put your game through Greenlight first. For Greenlight submissions, please see the following article:


Now that you are a Steam Partner you're required to start fill in all the relevant information about the game you wish to publish and sell. For that you need to navigate to the Steamworks Website and login with the account that you wish to publish the game from (if the game has been Greenlit, then you need to use the same account as that which was used for the Greenlight campaign).

The first thing you'll need to do after signing in is add a build account which has the ability to edit App Metadata and Public App Changes to Steam. This can be done by clicking the Users & Permissions link in the navigation bar and then clicking Manage users as seen here:

NOTE FOR GREENLIGHT DEVELOPERS: If your game has gone through Greenlight then you will already have an Admin account and an AppID will have been assigned to your game and an initial Steamworks section prepared. This means you can skip the following and go straight to the section on Edit Steamworks Preferences

At the top right corner click the Add button and then fill in the relevant information whilst enabling the suggested preferences:

Navigate back to the homepage and you'll see information about creating a new application, so let's start working on that no. Click the Create new app button as can be seen here:

This will open the following form:

Fill in these fields and click Create Now, you'll see another prompt which contains a list of ids for specific packages - only close this prompt once you've noted the ids!

Now that your application has been created, click the Users & Permissions link then View Applications:

Edit Steamworks Preferences

If you click on your application, this will open the landing page for it. The landing page contains all the relevant information about your application such as Store Page information, Release Date, System Requirements, Adding promotion artwork/videos, Setting the platforms for your application and most notably how to launch your application. Under the Technical Tools heading click Edit Steamworks Settings:

This will open the General Application Settings page, under the Application Name and Type section confirm that your game name and type are correct. Next under the Supported Operating Systems page check which operating settings you wish to support, you’ll also see a Community Release State section which is used to show when your application appears on the store, change this as required.


Next click on Installation > General

By default your game has no launch options so click the Add New Launch Option button

Now that you have your Launch Option click the Edit button and start filling in the relevant information, by default Launch Option 0 will ignore the Operating System selected unless you add more, it is suggested you create a unique Launch Option for each target platform and fill in the relevant information, when filling in the executable name field you'll need to point it to the correct file, for GameMaker compiled applications this is as follows:

Next up we need to create Depot(s) to store the files for our application, to get there click the SteamPipe Link and then Depots

By default Steam should create a depot for your application, and each Depot has its own unique id which you'll need to note for later. Ignoring that for now, it's suggested that you rename your Depot to have a relevant name such as "Windows Content" or "DLC 1" to keep it clear what it should contain. You can edit these to be Language Specific, Platform Specific or to only work with a specific DLC also. For example you can set up your depots like this:

Once you have filled out all the relevant information, you must press the "Save" button otherwise the changes won't be pushed to the Steam server in the following part. Recent changes to this page have also exposed the Depots Languages settings which also must be filled in, once you have selected the languages you wish to manage press the “Save” button:

So, once you have saved those changes locally, you will need to publish your changes to the Steam server. Click the Publish link now to do that:

Upon opening this page you’ll see the following screen:

It's suggested that each time you make a change to your application that you click the View Diffs button before publishing to review what you have done. Once you've reviewed your changes and are ready to publish then click the Prepare for Publishing button, click the Publish to Steam button, fill in the text field with the on screen code and then click Really Publish.

This has now published the changes you made to your application, just to note that unless your game is released this won't make your application public. Finally navigate back to your landing page and click on the package shown at the top of the page.

You'll see that it has a section for Depots Included, click on the Add/Remove Depots button and update these as required.

This article only covers setting up your game on the Steamworks dashboard, but it doesn't cover the Steamworks SDK and getting your game to use it to communicate to the Steam API. We'll cover that in the following article:
