On December 3, Aeterna Lucis will finally be in your hands
To our entire Aeterna community: the wait is over. We are thrilled to announce that the direct continuation of our universe, Aeterna Lucis, will launch worldwide on December 3, 2026, for $24.99 / €24.99.
Taking this extra year was never a burden or a painful grind. Quite the opposite: we allowed ourselves the privilege not to rush, to nurture the game down to its core, and to pour countless hours into every single hand-drawn frame and seamless area until it carried a true soul of its own.
With genuine humility, we believe our Queen will shine with an extraordinary light in the Metroidvania genre, and we know you will feel all that passion the moment you pick up the controller.
What will you find in Aeterna Lucis?
Watch on YouTube
Seamless interconnected world: Fully fluid exploration from end to end, with zero loading screens or artificial interruptions.
Dynamic real-time lighting: A completely revamped engine where light reacts instantly with your weapons, projectiles, enemies, and environments.
Hyper-detailed artistic map: A handcrafted miniature replica of every room at real scale with full decoration, allowing you to orient yourself at a glance.
Visual storytelling through stained glass: Lore shared in an elegant, visual format designed to expand the story you already know.
Aeterna Mode: A balanced, accessible curve focused on exploration, atmosphere, and platforming without frustrating bottlenecks.
Lucis Mode: An uncompromising, relentless challenge designed for those eager to relive the purest difficulty of the saga.
Rock-solid performance & rebuilt systems: Ground-up rework of save routines, clean memory management, and instant input response from day one.
If we can continue creating and expanding this universe without publishers or massive corporations behind us, it is entirely because you were there supporting our previous games.
Thank you from the bottom of our hearts for walking this journey with us and making it possible for the saga to go on.
Mark December 3 on your calendar and add Aeterna Lucis to your wishlist to join us in this next chapter!

Aeternum Game Studios and Studio Koba present: Future Knight

Hello, community!
Today we share an exciting step in our journey. After years of walking the path of independent development individually, we have decided to join forces with Studio Koba (creators of Narita Boy) to co-develop a very special project.
We want to make it clear that both studios maintain our total independence. This strategic alliance was born specifically to bring to life a new IP that merges the best of our visions: Future Knight.
What is Future Knight? It is a 2D action and Shoot 'Em Up odyssey with a "backlit" aesthetic that pays tribute to classic 80s LCD handhelds. The game combines our technical precision with Studio Koba's overflowing artistic creativity.
Choreographic Action: You will simultaneously control the Future Knight and his bizarre companion "Two More".
Absurd Narrative: A story of revenge and oblivion that begins with a pyramidal sect in May 1993.
Unique Visual Identity: Complex animations and elaborate art integrated into the concept of a retro handheld device.
"Electro A Capela" Soundtrack: A cocktail of electronics and unexpected voices by Salvinsky.
This collaboration allows us to combine the veteran talent of both teams to offer you a purely indie experience.
Don't miss the first preview! 📺 Watch the Gameplay Teaser here:

The final release date for Summum Aeterna is getting closer! September 14 is almost here, and besides new playable content, the game will also include performance improvements, bug fixes, and a completely compatible version for the Steam portable console.
Our previous title Aeterna Noctis got the Steam Deck verification just two months after its launch day, so it is a matter of time before Steam finally reviews Summum Aeterna and grats us with the official verification.
For those who enjoy playing on Steam Deck, keep in mind that the game is playable in its current state:

In-game interface texts are legible on the console, allowing users to navigate through menus and skill trees just like on a monitor screen. You won't miss a detail about the game mechanics!
Summum Aeterna runs smoothly on the Steam Deck, the game adapts its graphics to the portable console. The artistic value and the beauty of the environments and characters do not affect the game experience.
The gameplay itself is perfectly suited to the features of the portable console. The game integrates all functionality available on the controller configuration.
Very soon Summum Aeterna will receive official verification by Steam to clear up any doubts regarding its compatibility with Steam Deck. Meanwhile, those of you who own the portable console will be able to play our Roguelite without issues and enjoy its incredible performance.
See you all on September 14!
