Lotte Innovate subsidiary Caliburse announced on the 11th that it conducted a large-scale update 2 months after the Caliburse launch. This update includes the second planet "TomorrowPlanet" born from collaboration with world-renowned EDM festival Tomorrowland, a virtual concert hall linked with MBC "Show! Music Core," and a virtual store for fashion brand MCM. TomorrowPlanet is Caliburse second planet, delivering a unique and dreamy feeling to users by recreating the subtle atmosphere of nature including forests, rivers, and waterfalls. The Tomorrowland partnership is strategically significant: Tomorrowland (Belgium) is the most prestigious EDM festival globally with a passionate international fanbase; having a permanent Tomorrowland presence in Caliburse gives the platform credibility with the music-entertainment audience; Caliburse brand as "ultra-realistic metaverse" is demonstrated by the quality of the Tomorrowland environment; the MBC Music Core virtual concert hall creates a second K-pop connection (following earlier K-pop collaborations) that leverages the Korean Wave for platform user acquisition; MCM (luxury fashion) virtual store demonstrates premium brand confidence in Caliburse as a brand-appropriate environment.
