The song was recorded on June 27, 2018 and released on July 27 via Mer Musikk and Ultra Music.

Two remixes were released, one by Austrian DJ and producer LUM!X and one by Afrojack in collaboration with Chasner.

The video before "All Falls Down", "Tired" served as a prequel to this trilogy where a solar storm destroyed all technology on earth, changing the course of humanity forever.

[1] The lyric during the chorus, "I see it, let's feel it, while we're still young and fearless" samples a part from the melody of the popular production music track "Heart of Courage" by Two Steps from Hell.

Together, with the accompanying music video, "Darkside" is the second song in the "World of Walker" trilogy, following the previous single "All Falls Down".
