The official Japanese website for Metroid Prime 4: Beyond has been updated. It now features the full in-game theme of the planet Viewros, which was first heard briefly at the end of the June 2024 trailer. The text on the site confirms that Viewros is the home planet of the Lamorn race seen in today’s trailer. It also re-affirms that Sylux (who didn’t appear in today’s trailer) holds a “deep grudge” against the Galactic Federation and Samus.
