The team has been working on and improving Proton for a while now, and it has a large amount of coverage. Most APIs are already supported by Proton, and most games work out of the box. We're continuing to improve Proton compatibility, and our goal is to get as close to full coverage as possible. …

Access to the tools is still a work-in-progress and this page will be updated with more information in the coming days. [section]Proton Anti-Cheat Support[/section] Proton supports some common anti-cheat middleware, including Easy Anti-Cheat and BattlEye. [list] [*][subsection]Easy Anti-Cheat[/subsection] Proton supports Easy Anti-Cheat without requiring any recompilation, but it does require you to manually enable support for your build. …

Steam does not contain any paid advertising, nor are advertising models supported in games distributed on Steam. There are varying interpretations for what constitutes ‘advertising’ in a game, so the examples below are meant to help guide developers as to what is and is not supported on Steam. …

We recommend taking advantage of [doclink=marketing/widget]Store Widgets[/doclink] and [doclink=/marketing/utm_analytics]UTM Analytics[/doclink] to help enhance and measure the effectiveness of any off-Steam campaigns. [/list] [section]Not Supported[/section] [list] [*]Developers should not utilize paid advertising as a business model in their game, such as requiring players to watch or otherwise engage with advertising in order to play, or gating gameplay behind advertising. …

[subsection]In-Game Purchases (Microtransactions)[/subsection] Microtransactions offer customers the option to purchase additional content while playing a game. With the Steam Microtransaction APIs, your Steam game can support all kinds of in-game purchases, including items, virtual currency, or any other content you’d like to offer. …

You will pass that information using the InitTxn API. We recommend entering pricing in your database in every supported currency so that users will see a price displayed in a currency they are familiar with. Otherwise, customers may see a price displayed in a currency they aren’t familiar with and will cancel the purchase out of caution. …

The API will automagically do the right thing here for stick based input, so you'll still get a tune-able stick input if your camera is applied to an analog stick (PS4/Xbox style) with full dead zones/response curves/etc. that you can specify in your default configuration. This same input will then work across joysticks, track pads, or motion control gyros (steam controller/ps4) as well as future support for mice. …

By default, this will only affect configurations already using Steam Input API as to not disrupt existing players who have been using Steam Input to existing gamepad support. If you're removing XInput or other gamepad APIs then you will want to set the "major_revision_affects_xinput" flag in order to update existing players. …

It's up to you to decide what accessory types to support, and what cosmetic or gameplay effects different accessory types might have. You may also choose to support different types of accessories on different item types in your game. …

Some developers will choose to participate in Next Fest early in their development cycle to learn more about what customers enjoy.

This has many of the same benefits of following a developer, except that it is scoped to just products that are part of that franchise. When a Steam customer follows your franchise, they are giving Steam a strong signal that they enjoy that content and allows Steam to expand the customer store experience in the following ways: [list] [*] [b]Email notification[/b] - Followers of your franchise will receive an email when a game in your franchise releases or enters early access or exits early access. [*] [b]Featuring games[/b] - When followers are browsing either the Steam front page or a genre and/or tag Steam hub page, Steam will mix in recently released games from the franchise into the main capsules on those pages. …

Developers can now indicate which accessibility features they support, and these will be displayed on the Steam store page for those games. Additionally, players can specifically search for games that support these features. …
