While only a couple of titles are officially confirmed for Xbox Game Pass in March 2025 so far, the library is expected to grow. Microsoft typically announces new additions bi-weekly, but release date reveals often give subscribers a sneak peek of what's to come.

Thanks to recent announcements, we have a good idea of the Game Pass lineup through May. Events like the Xbox Developer Direct and ID@Xbox have provided valuable insights, although March appears less packed compared to April and May.

Currently, two games are confirmed for March 2025: the 33-player co-op roguelike, 33 Immortals, launching in early access on March 18th, and the single-player survival game, Atomfall, arriving on March 27th.  33 Immortals offers massive, MMO-raid-like experiences, while Atomfall provides a Fallout-esque single-player adventure.

It's highly probable that more titles will join 33 Immortals and Atomfall in March.  If Microsoft follows its usual pattern, new additions for the first half of March should be revealed soon.  Stay tuned for updates.

April is shaping up to be a busy month for Game Pass. South of Midnight arrives on April 8th, followed by Commandos: Origins and Descenders Next on April 9th.  Blue Prince debuts on April 10th, Tempopo launches on April 17th, and the highly-anticipated turn-based RPG, Clair Obscur: Expedition 33, joins the service on April 24th.

May 2025 is also looking promising, with the co-op adventure Revenge of the Savage Planet arriving on May 8th, Doom: The Dark Ages on May 15th, and the unique title To a T on May 28th.
