The game comes with 10,000 new images and 100 video clips of BTS.“Those alternate realities are based on some of the members’ interviews, and they said, ‘If I wasn’t in BTS band, my vision was this’,” Simon Sim, president of South Korean mobile gaming company Netmarble Corp, which developed the game, told Reuters Television.The game allows fans to be involved in video calls and texts with BTS members, including cheering them up if they are feeling down.BTS first formed in Seoul in 2013 and broke through in the US pop market in 2017, becoming the first Korean group to win a Billboard music award.Three new songs from the game - "All Night", "Dream Glow" and "A Brand New Day" - were released earlier in June.
