He worked too on an official remix of League of Legends theme. Alan Walker has already made some songs for the video game community, like his first single for PUBG, " On My Way", which was released on 21 March 2019, celebrating the first anniversary of the game.
The song serves as the official anthem for PlayerUnknown's Battlegrounds game, also called PUBG Mobile, a battle royal game on Android and iOS, which has 50 million active daily users. The rapper refers to it in the lyrics of the song when he says "2013 I went wild for night, in 2019 I'm getting out 'fore I die". But I would like to speak out for fair treatment and a quick resolution for the sake of everyone involved." The track marks the second collaboration in electronic domain for ASAP Rocky after "Wild for the Night" by Skrillex in 2013.
After the release, Alan Walker posted a message on Instagram to thank all his staff and appeal to justice for the rapper: "The challenges and controversy surrounding Rocky's arrest and upcoming trial in Sweden has affected all of us through the last weeks. The vocals of the song were recorded before the incarceration of ASAP Rocky, due to an altercation in the streets of Stockholm, in Sweden, on 30 July. It is written in the key of G minor with a chord progression of Eb-Dm-Gm. The song is set in common time and has a tempo of 88 beats per minute.
