TL;DR
Steam Controller owners have discovered a secret feature that makes the device emit a Wilhelm scream when dropped. The feature uses haptic motors to simulate the scream and can be triggered intentionally or accidentally. Its existence was confirmed by Engadget and Reddit users.
The Steam Controller has a hidden Easter egg that causes it to emit a Wilhelm scream when dropped, confirmed by Reddit users and verified by Engadget. This feature is purely software-based and involves no hardware modifications, making it a harmless surprise for owners.
The discovery was made by Reddit user u/RF3D19, who posted a video showing their Steam Controller emitting a Wilhelm scream after being dropped. Engadget confirmed the feature’s existence through testing. The scream is produced by the controller’s haptic motors, as the device lacks a traditional speaker. The Easter egg appears to have a timeout of approximately one minute, after which the scream may no longer trigger. Users report that the feature can be activated on soft surfaces like beds or pillows, and it is not dependent on the controller hitting a hard surface.
The feature was initially met with skepticism, with some users questioning whether it was a prank or a glitch. However, multiple Reddit comments and Engadget’s verification confirmed it as an intentional Easter egg. The controller’s $99 price point and widespread use make this a notable discovery among gaming hardware enthusiasts.
Why It Matters
This discovery highlights the playful side of gaming hardware design, showing that manufacturers sometimes include hidden features for fun. For users, it adds an element of humor and surprise to their gaming experience. While it does not impact the controller’s performance or durability, it raises awareness about potential Easter eggs in other devices. The feature also underscores the importance of software-based hidden features in modern hardware, which can be activated or revealed through specific actions.
