Valve's Steam Controller features a hidden easter egg that makes it emit a classic Wilhelm scream when dropped, discovered by Reddit user u/RF3D19. The controller uses haptic motors instead of built-in speakers to simulate the sound, as confirmed by Engadget. This quirky feature has sparked playful experimentation, with users testing drops on soft surfaces like beds.

However, the easter egg has a ~60-second reset timer, meaning repeated drops within that window won't trigger the effect. While some remain skeptical about its authenticity, the revelation highlights Steam's penchant for cheeky developer humor.
