Warning Call (Theme from Mirror's Edge Catalyst)

This is the main theme song for the video game Mirror's Edge Catalyst, a reboot of mid-'00s action adventure Mirror's Edge. Multi-instrumentalist Iain Cook said: "The sound of Chvrches' music resonates with the minimalist sci-fi dystopia of the Mirror's Edge world, and we feel that the song complements the drama, emotion and empowering themes of [video game character] Faith's story."

The song's lyrics, written by frontwoman Lauren Mayberry, are from the perspective of the game's protagonist Faith, depicting her "world, struggles, and strength." Faith is a rare case of a non-sexualized female leading hero in the medium. Mayberry notably penned an article for The Guardian in 2013 criticizing "the casual sexual objectification of women."
