This sound comes from Rust, the multiplayer survival game developed by Facepunch Studios. C4 is one of the game's most recognizable raiding tools, so its audio became familiar through raid videos, PvP clips and short-form gaming edits. Online, creators use the arming sequence and explosion to signal that something big is about to happen, even outside Rust-specific content. Its staying power comes from that clear structure: a brief warning, then an unmistakable destructive payoff that lands well in fast edits.
