Guild Wars 3 lands Kazuma Jinnouchi as lead composer

ArenaNet has confirmed Kazuma Jinnouchi as the lead composer for Guild Wars 3, the studio's upcoming MMORPG. Jinnouchi is best known for scoring post-Bungie Halo titles, Metal Gear Solid V, and various Star Wars projects.

Alongside the announcement, ArenaNet released a behind-the-scenes video showing how the Guild Wars 3 main theme was built from the ground up. The video features Jinnouchi working with ArenaNet audio lead Chase Thompson and music lead Nadia Wheaton. He's not working alone — contributing composers include Asuka Ito, known for Rhythm Heaven and PilotWings, and Maclaine Diemer, who has been composing for Guild Wars 2 for years. Thompson's early framing of "respecting the legacy" signals that the new soundtrack aims to carry forward the grand orchestral sound that defined the first two games, and the main theme heard in the video fits that description well.

Guild Wars 3 was revealed at Summer Game Fest earlier this year, and ArenaNet has been steadily feeding out new details since — most recently around the game's narrative and how magic systems like signets and spirits might function. Jinnouchi's hiring is another meaningful signal that the studio is treating this as a full-scale production rather than a quiet follow-up. Guild Wars 2 built a loyal fanbase partly on the strength of its music, so landing a composer with Jinnouchi's resume is a deliberate move to set expectations high.

The main theme is already live on YouTube for anyone who wants to judge for themselves. With composer lineup, narrative hints, and a main theme all out in the wild, ArenaNet appears to be building momentum steadily ahead of whatever the next major Guild Wars 3 reveal turns out to be.
