A new Xbox Game Pass tier has been discovered in leaked code, confirming rumors about Xbox's plans to expand its subscription offerings. The new tier, codenamed 'Triton,' will feature only Xbox Game Studios titles, excluding third-party games that are available on the standard subscription.

According to analysis by Better xCloud, an open-source service that enhances Xbox Cloud Gaming, the code reveals a subscription tier that could be ad-supported and either free or low-cost. This strategy would allow Microsoft to eliminate licensing fees by focusing exclusively on its own first-party catalog. The move comes as Xbox's new CEO Asha Sharma reportedly plans to announce changes to attract more subscribers.

The confirmed game lineup includes popular titles like DOOM Eternal, Halo 5, Fallout 4, and The Elder Scrolls Online. This first-party approach leverages Microsoft's extensive studio acquisitions over the past several years and could potentially serve as the foundation for rumored partnerships, including possible bundling with Netflix subscriptions.
