Arc Raiders is a PvPvE extraction shooter developed by Embark Studios, set on a ruined Earth where raiders scavenge the surface while ARC machines patrol from orbit. Flares are a core signaling tool in the game, used to mark positions, call attention, and communicate without voice chat. As clips from matches spread on TikTok, YouTube, and Discord, the flare launch and burst became a recognizable shorthand among players. Outside the game, creators reuse it as an instant signal sound, borrowing its urgency and clarity even for viewers who have never played.
