Cocone's AlterEgo City.

Cocone debuts AlterEgo City as 1st foray into U.S. gaming

Cocone debuted AlterEgo City as its first foray into the U.S. gaming market. The mobile game is available on iOS and Android as a digital playground for art, fashion, and music.

Japan-based Cocone started in Japan with its digital fashion focus, and it has seen more than 140 million downloads and 17 billion digital items sold.

AlterEgo City, formerly known as Centennial and AlterEgo City, invites players to step into the realm of Centennial, a meticulously crafted environment offering lots of customization options. Players can design and personalize their unique digital avatars, from collecting designer digital fashion items to decorating their virtual living spaces within the city.

One of the game’s highlights is the ability for players to select their own unique companion, an Alter Ego, which can evolve into various forms based on in-game choices. AlterEgo City goes beyond typical gaming experiences by allowing players to produce their own music, creating custom tracks that resonate through their AlterEgo. The extensive customization features extend to sharing these creations with friends online, fostering a dynamic and user-driven social environment.

Mari Kim, CEO of Cocone Xenon and the lead creative visionary for AlterEgo City, said in a statement, “Starting today, players can experience the incredibly vibrant and densely packed world of AlterEgo City and have the freedom to express themselves however they see fit, through art, music, and fashion that they choose. With virtually endless customization options, we can’t wait to see what the player base creates within our world, where they can be the version of themselves they have always envisioned.”

Cocone was founded in 2008 and now it is expanding its reach into the global gaming market.
