Marvelous USA Inc. (formerly Xseed Games) is an American video game company founded in 2004.

The company was founded in 2004 by former Square Enix USA employees, with the goal of localizing Japanese games for the American market. In 2007, AQ Interactive, Inc. announced the acquisition of Xseed Games, with share transfer before June. The deal was signed on April 24, and the share transfer was completed on June 26.
Xseed Games joined forces with Marvelous Entertainment (MMV) to co-publish its games in North America in 2008. At E3 2008, MMV USA and Xseed Games distinguished the games that would be co-published under the agreement and the games that Xseed would publish separately.
In April 1, 2009, AQ Interactive announced it would be increasing its stake of Xseed Games from 55% to 90%.
On April 14, 2009, Xseed Games announced a partnership with Japanese developer Nihon Falcom. It would go on to localize and publish Ys Seven, Ys: The Oath in Felghana, Ys I & II Chronicles, and the Trails in the Sky trilogy for the PlayStation Portable in North America. Xseed Games later published Ys: The Oath in Felghana and Ys Origin as its first releases on the Steam digital distribution platform in 2012.
In March 2013, Index Corporation's Atlus Online Division online business unit was purchased by Marvelous AQL and transferred to Xseed. On April 6, MarvelousAQL announced that XSEED JKS, Inc. would be renamed to Marvelous USA Inc., with the Xseed banner being used for video games and the Marvelous Online banner would be used for mobile and social titles.
In October 2019, company cofounder Ken Berry was named its president, CEO, and CFO.
In August 2024, Marvelous announced that Marvelous USA would undergo a major restructural change. The Xseed Games banner would now be used for third-party titles, while the Marvelous USA banner would be used for Marvelous' titles.
In 2019, former Xseed localization producer Brittany Avery discovered that she was not credited for her work on the enhanced PlayStation 4 port of The Legend of Heroes: Trails of Cold Steel after leaving the company the previous year. As a result, Xseed revealed its policy of not crediting staff members in games if they are no longer employed at the company at the time it releases. The practice, also done by some other companies in the industry, was widely criticized.
