The Steam Controller has a hidden Wilhelm scream, and people are dropping it on purpose

Valve's Steam Controller contains a hidden Easter egg: when dropped while in Steam Big Picture mode, it occasionally plays the iconic Wilhelm Scream sound effect through its haptic motors. The effect works on soft surfaces like beds or pillows, has a cooldown, and doesn't trigger every time. The discovery was shared on Reddit and has since gone viral, with people intentionally dropping their controllers to hear it.
