The Steam Controller can emit a Wilhelm scream when dropped, a feature confirmed by Engadget and discovered by a Reddit user. This easter egg uses haptic motors to simulate the scream, making it a playful hidden feature for users.
The feature was identified by Reddit user u/RF3D19 and confirmed by Engadget. It involves the controller emitting a scream-like sound using its haptic motors, despite lacking a traditional speaker. The easter egg appears to activate upon dropping the controller and has a timeout period of about one minute, after which it resets.
