No Man's Sky is a space exploration and survival game developed by Hello Games and released in 2016, built around procedurally generated planets, trading and space combat. Freighters are large capital ships players can own and command, and when hostile ships attack one in orbit, its internal alarm activates to warn the crew. Clips of that short warning tone have since been shared on soundboards as a clean, game-accurate alert, reused by creators who need an instant sci-fi danger cue without music or dialogue underneath.
