In May 2026, there are two highly anticipated releases coming to Xbox Game Pass at day one of their respective releases. And of course, more could be announced between now and then. The first of these two games is Forza Horizon 6, which is poised to be one of the biggest releases of 2026. The second of these two day-one Xbox Game Pass games is Subnautica 2. There are other confirmed day-one Xbox Game Pass games for the month of May, including Xbox Game Studios’ Kiln and Mixtape, but these releases aren’t as noteworthy in comparison.
Forza Horizon 6
Forza Horizon 6 needs little introduction. It’s a new Forza Horizon game from Playground Games, set in Japan. As you may know, Forza Horizon has become Xbox’s premier series in terms of critical success, which it combines with commercial success as well, something no other Xbox series has done as of late. It is set to release on May 19, and will be available with Xbox Game Pass Ultimate and PC Game Pass the moment it does.
Subnautica 2
Subnautica 2 has been a long time coming, considering the first game released back in 2018 to an 87 on Metacritic and millions of copies sold. The first game was one of the breakout indie successes of the last generation, and fans have been patiently waiting for a true sequel ever since. It is worth noting, though, that when Subnautica 2 releases, on PC and Xbox Series X, it will be in early access. Meanwhile, there is no word of an exact release date in May either, just a general May window.
