The theme comes from Halo: Combat Evolved, released in 2001 for Xbox and developed by Bungie, with music composed by Martin O'Donnell and Michael Salvatori. Its chant led opening became one of gaming's most recognisable motifs, returning across sequels, trailers and remixes. Bass boosted edits spread through YouTube and soundboards, exaggerating the drums and low choir for meme use. Players still use it to signal instant nostalgia and mock epic importance, long after the original menu screen first made it iconic.
