On Windows, any game with Direct Input support will work with the Stratus XL controller out of the box. This includes many fighting and racing games released in the past decade.
To enable full Windows and Steam game support for the Stratus XL for Windows and Android, install SteelSeries Engine 3. After installing SteelSeries Engine 3 and power cycling your controller for the first time, the Stratus XL for Windows and Android will now show up as an X-Input (Xbox style) gamepad, enabling support for thousands of games on Windows and Steam.
In Steam look for "Full Controller Support" on the game store page to see if it is compatible with X-Input and your Stratus XL for Windows and Android.
Out of the box, your Stratus XL for Windows and Android will work with any controller enabled* game. Simply pair your device and game!
*Unfortunately we do not have a list of controller supported games available. Our recommendation is to read the app/game description and if information isn't provided there, to read some of the reviews, since it is likely to be explained there.
