This sound is associated with Counter-Strike 2, Valve's updated version of Counter-Strike released in 2023. Footstep audio is central to how players read movement in matches, so short walk clips quickly became useful in memes, shorts and reaction edits about timing, sneaking and map awareness. Creators reuse it because even a few seconds of CS2 movement sound can signal pressure, danger or a blown play to anyone familiar with competitive shooters.
