Steam has the ability to provide free demos for your customers so that they can try before they buy.
It's up to you whether or not a demo will be beneficial for your title, but there are a couple of useful things to consider:
- Quality – Customers are generally using the demo to make a purchase decision on your game. Make sure that what you put out there is high quality and measures up to the real experience.
- Timing – When you release your demo is also important. We generally recommend waiting until launch, but there are circumstances where putting a demo out prior to release is effective. If, for instance, you feel like customers need to touch the game to really understand it, then a quality demo prior to release can be useful.
- Length – You need to balance giving the customer enough content to get them excited, without giving away so much that they feel like they've experienced everything the game has to offer.
Demos are created as a separate App ID as the base app.
The demo will need to be configured with depots, and builds must be created just like a full app. The demo will live on the base game's store page as a button where users can download and try out the game for free.
To create your demo App ID:
- From the App Landing Page, click on "All associated packages, DLC, demos and tools."
- At the top of this page, click the "Add Demo" button.
- The demo you created has its own release checklist and configuration, similar to your base product.
To work properly for customers, your application type must be set as 'Demo' and the App ID of your base game entered in the General Application Settings
section of the Steamworks website for your demo. However, this means your primary account will own both the demo and the base game, thus only letting you launch the base game (this is default behavior for customers too, as there's little reason to let a customer launch a demo once they own the base game).
To get around this and test your demo, you will need to request keys for your demo and activate them on test accounts that do not own the full product.
Minimizing Upgrade Impact
There are a few things you can do to minimize the friction to upgrade from the demo to the full game.
- Share depots with the full app: For any content that's shared between the full app and the demo, put it into its own depot and mount the shared depot from the base app into the demo app. See the Shared Content Depots documentation for more info.
- Share cloud storage with the full app: The saved game from the demo can be stored to the full game's cloud storage so that users can pick up where they left off in the demo once they buy the full game. See the Steam Cloud documentation for more info.
Marketing the Full App
You can direct customers to the full app from your demo by utilizing the Steam Overlay. The in-app overlay allows you to put a link to the store page right in your app. See the Steam Overlay
documentation and ISteamFriends::ActivateGameOverlayToStore
for more details.
Using Achievements in Demos
We recommend that you disable achievements in demos. Instead, store the saved game in the shared Steam Cloud as described in the Cloud documentation
. Then grant those achievements on loading the game in the full game after the user has purchased.
Releasing And Updating Your Demo
To prepare for release, please make sure to complete the checklists found on the right-hand side of the landing page for your demo. Once completed, you can mark your demo page and build as ready for review.
If you are releasing your demo prior to your base product being available, you probably want to prepare your base game's store page and make sure it is visible as 'coming soon' so users can add the full game to their wishlist (also see: Steam Wishlists
). Once released, the demo can show up as new in the demo section. Clicking on the demo capsule in the store will take users to the main game's store page where there's a demo button on the side.
Please see the Preparing for Your Release
documentation for general information about preparing any app for release.
Frequently Asked QuestionsQ: Can my demo users play Steam multiplayer with my full game users?
A: Steam currently doesn't support multiplayer matchmaking between the full game and the demo.Q: What if my demo consists of literally the same files as the full game?
A: Use a shared depot as described in the Shared Content Depots
documentation. Do the following to make sure the demo and full app both work correctly.
Q: How to get the Demo to show up on the base application's store page?
- If you use Steam DRM, re-submit the exe for signing on the demo Steamworks app admin. Package the demo exe into a depot specific to the demo app. Alternatively, you can skip Steam DRM and just call SteamAPI_RestartAppIfNecessary.
- If there is behavior that is restricted to owners of the full app, gate it behind the ISteamApps::BIsSubscribedApp Steamworks API call with the App ID of the full app.
