Smilegate Unveils 'OVER//RIDE' – The Soundtrack for Chaos Zero Nightmare
On July 18, 2025, the renowned gaming company Smilegate announced the release of a new original soundtrack (OST) titled 'OVER//RIDE' for its upcoming role-playing game (RPG) 'Chaos Zero Nightmare' (commonly referred to as CZN). This is an exciting development for fans, not only because it symbolizes a notable addition to the game but also due to its collaboration with the globally celebrated virtual idol group, hololive English.
A Collaboration of Star Power
hololive English has skyrocketed to fame, boasting over 90 million subscribers on YouTube, and is known for its unique blend of virtual performance and fan engagement. In this new OST, two standout talents from hololive,
Mori Calliope and
Nerissa Ravencroft, contribute their remarkable vocal abilities, adding a dynamic flair to the game’s atmosphere. Mori Calliope alone has garnered over 2.55 million followers on her YouTube channel, while Nerissa delights around 890 thousand fans with her engaging performances. Remarkably, Mori’s solo concert held in Los Angeles earlier this year was a complete sell-out, highlighting her prominent appeal in the music industry.
Musical Composition and Themes
The OST track 'OVER//RIDE' showcases a fast-paced fusion of rock and metal, designed to echo the intense and dramatic sequences of CZN. Lyrically inspired by the game's rich lore, it conveys a compelling message that emphasizes perseverance and hope, even when confronted with overwhelming despair. The collaboration not only integrates music into the gaming experience but also builds a deeper emotional connection for the audience.
Available immediately across various platforms including CZN’s official channels, Apple Music, YouTube Music, Spotify, Melon, and Bugs, the track is easily accessible for all fans to enjoy. In addition, a music video featuring both vocalists has been released on YouTube, enhancing the auditory experience with stunning visuals. Smilegate has also announced plans for an additional animated music video in the future, promising further engagement with its audience.
Voice of Excitement from Smilegate
Kim Joo Hyung, who heads the business division at Smilegate, shared his enthusiasm regarding this unique collaborative effort stating, “We're truly delighted to have worked with such incredible virtual artists. We hope everyone enjoys the OST, which captures the lore and atmosphere of CZN through music.” His comments underscore the importance Smilegate places on enriching the player experience not only through gameplay but also through music that resonates with the story.
