SCP-106 is a well-known monster from the SCP Foundation universe, often called the Old Man by fans. This walking sound is commonly used in SCP game content, especially clips inspired by or taken from SCP: Secret Laboratory, where the character’s approach is a major tension cue. The audio spread through gameplay videos, short horror edits and meme compilations because it instantly signals that something dangerous is nearby. It remains popular because even a few seconds of those footsteps can create dread without showing the threat directly.
