Mega Stomp Panic - Audio Reality Experience

“Mega Stomp turns you into something rad, no experience necessary. When you walk, Mega Stomp will make you sound like you’re a robot, a zombie, a monster, or even splashing in the rain. Every time you step or stomp, the mega stomp senses your movement and plays an appropriate sound effect to complete the audio illusion.”
