Mega Man Zero launched on Game Boy Advance in 2002, developed by Inti Creates for Capcom as a darker follow up to the Mega Man X series. Players control Zero in side scrolling missions given by the Resistance, and each deployment opens with interface cues and announcements that mark the transition from briefing to action. The short start sound became familiar through repeated play and later through emulators, playthroughs and soundboards, where fans reuse it outside the game as a recognizable signal that something is about to begin.
