Project Zomboid is a hardcore isometric zombie survival game developed by The Indie Stone and in early access on Steam since 2013. Its jumpscare sting became familiar to players because death is permanent and most encounters begin in silence, making the sudden cue a shared moment of dread. Clips of streamers reacting to it spread on YouTube and TikTok, and editors began lifting the sound for other horror contexts, often alongside the FNAF jumpscare scream in scare compilations and meme edits.
