Luna Abyss added to Xbox Game Pass with positive reviews

Luna Abyss, a first-person shooter (FPS) developed by British studio Kwalee, launched on 21 May 2026 as part of Xbox Game Pass. This marks the 13th new title added to the subscription service in May 2026 and the 85th Xbox Game Pass release since the start of the year.

Overview of Luna Abyss

Luna Abyss is set inside a decaying alien megastructure, where a lone prisoner is condemned to scour underground ruins for ancient technologies and answers about the collapse of the civilization that once lived there. The game blends a sci-fi narrative with fast-paced action, putting players through shootouts and platforming elements.

Release information

The game officially launched on 21 May at 9 a.m. ET. Luna Abyss is available not only on Xbox Series X/S, but also on PlayStation 5 and PC. It is also being added to Xbox Game Pass as a day-one release, giving subscribers to both PC Game Pass and Xbox Game Pass Ultimate immediate access to the game.

Development and reception

Kwalee, the developer behind Luna Abyss, has recently gained some attention for its earlier project, a GTA-inspired game called The Precinct. Luna Abyss originated from a demo released in July 2023, which received "very positive" reviews on Steam, and that favorable reception appears to have carried over to the full game.

Reviews for Luna Abyss have been generally positive, with a "Strong" rating on OpenCritic based on an average score of 78 and a recommendation rate of 85%. Critics describe the game as a stylish, compact experience with a distinctive narrative. Its atmospheric setting and challenging boss encounters are praised, although some reviewers note inconsistency in the game's action.

Upcoming releases on Xbox Game Pass

Alongside Luna Abyss, more titles are expected in the coming weeks, including Escape Simulator on 26 May, Echo Generation 2 and The Outer Worlds: Spacer's Choice Edition on 27 May, and several other games launching later in the year. These ongoing additions to the Xbox Game Pass catalog suggest a strong focus on expanding the service with relevant and popular titles.

With the addition of Luna Abyss to Xbox Game Pass, Microsoft continues to refine its strategy of offering players a diverse catalog. This day-one release trend is a key part of its model, helping it put pressure on the competition while giving gamers an attractive value proposition.
