A behind-the-scenes video was also released by NCSOFT West showing EXO-CBX as they record the song. Not only that, a video of their performance during the Busan event had also been released.
"Blade & Soul" is an MMORPG, a massively multiplayer online role-playing game, wherein one would have to assume the role of a character and play in a virtual world.
While EXO-CBX may only have debuted as a subunit of EXO last October, it is amazing to know that even as a subunit, they are all doing quite well on their own and that they managed to get involved in a project such as this even with their busy schedules. The group had just recently won "Album of the Year" during the 2016 Mnet Asian Awards.
Here's to hoping EXO-CBX continue to do more projects together in the future!
