The hand-drawn Metroidvania will arrive digitally on the Nintendo eShop worldwide on 3 December 2026.
The announcement positions Aeterna Lucis as a continuation of the Aeterna Universe while highlighting a renewed focus on tightly tuned exploration and platforming.
Players assume the role of the Queen of Light and traverse a vast interconnected world rendered in the series signature stained-glass aesthetic.
The developer frames Aeterna Lucis as their most distilled Metroidvania yet, emphasizing a refined balance of exploration and combat alongside expanded traversal mechanics.
Aeternum Game Studios also outlines two distinct playstyles designed to cater to different audience segments.
Rewritten from the developer's statements, the two modes break down as follows:
- Aeterna Mode.
Recommended for most players and newcomers to the franchise, this mode balances exploration and combat for an accessible but complete Metroidvania experience.
- Lucis Mode.
Targeted at seasoned players, this option increases platforming difficulty and presents more demanding boss encounters for those seeking a hardcore challenge.
Key verified features listed by the developer include:
- Seamless interconnected world with zero loading screens to preserve exploratory flow.
- A new real-time dynamic lighting engine that interacts with combat, weapons, projectiles, and environments.
- A detailed, full-scale miniature map intended to help players navigate each region and its decorations.
- An allegorical stained-glass lore system designed to be approachable for newcomers while offering deeper narrative layers for series veterans.
- Rebuilt optimization, including overhauled save systems and a target of stable 60 frames per second on PC and consoles from day one.
Aeterna Lucis continues the aesthetic and narrative lineage established in Aeterna Noctis while presenting clear accessibility and difficulty options for a broad audience.
With the Nintendo eShop release date set for 3 December 2026, Switch owners will be able to download the title at launch.
