The sound comes from SCP Secret Laboratory, the multiplayer horror game based on the SCP Foundation universe where players navigate a facility in chaos. Grenade and trap effects are part of its combat soundscape, used when explosives detonate during chases and room ambushes. Short clips like this spread through gaming soundboards and edit communities because the blast is instantly readable even without gameplay footage. Creators reuse it outside the game as a generic hidden trap cue, keeping its association with SCP ambushes and sudden player deaths.
