Perhaps this journey will reveal the connection between the world of El Shaddai and your own memories.

We invite you to experience this new "Mythical Concept" —
and we would be thrilled if you shared your impressions with us!

To everyone eagerly awaiting STARNAUT,

Currently, we are still awaiting approval from Valve for the final review, and the full release has not yet gone live.
We will proceed with the full release as soon as the approval is granted and everything is confirmed.

We sincerely apologize for the inconvenience and appreciate your patience and support.

Ladies and gentlemen, it's finally tomorrow.



The Mythos Concept Star Notebook is finally ready for full release on Steam.

It's been a process of trial and error over the past few years.
But the feedback, bug reports, and words of support we received during the Early Access period ......
all helped us in our development.

In the final version, we have completely adjusted the stage structure, enemy patterns, UI, weapon balance, and more.
In addition, please pay attention to the unexpected connection with "that character" in the story.

Your journey will surely change something.
See you in space tomorrow.

Only 2 more days until the release



Today, we introduce the characters!
Here is a sneak preview of their unique personalities 🚀.



Copiasu

“All right, reset time! I‘m feeling great!”
The 8th Designer Baby created by Stella. Driven by the dream of one day becoming a Starnaut and meeting Stella, he continues fighting. However, he actually received that title from Stella right from the start—he simply is too shy to claim it himself. With his incredibly positive personality, he charges forward fearlessly, no matter what kind of enemies may stand in his way.

Stella

“When in doubt, use your fists!”
The guide to Copiasu’s game journey. Originally created as the central AI brain of Seven Nights, she takes on an automatically generated form when emerging to the surface, which can change slightly each time. The form pictured is how she appeared in her first meeting with Copiasu, and is the version of her that Copiasu trusts and cherishes most as his beloved Stella. Stella tries to maintain this form for Copiasu as much as possible, although she finds it a bit chilly during the winter.

Wonderful

“Hmm... WONDERFUL!”
The physical manifestation of Wonderful chat, an AI chatbot created after Stella. He once served as an aide to Copiasu, but has since devoted himself to serving as a support role in his original form as a chatbot AI. You may occasionally spot him in his physical form as he runs around the stage with Lost Data in hand. If you spot him, make sure to give him a punch!

Dislikes Being ignored





Shopnaut

“.........”
A cool and nihilistic arms dealer. Once you’ve saved up enough money, you can buy weapons from him. No matter what happens, he’s always around. He’s strict when it comes to money, but surprisingly nice, even holding sales from time to time. However, he never speaks.

Hello!
This is the STARNAUT development team.
Only 3 days left until launch!



Today, we’d like to share something fun to know before you start playing — a quick dive into weapon builds!

In STARNAUT, you can equip up to 8 weapons at once.
With categories like Antenna, Explosive, and Collision, the combinations are endless — and every loadout brings a completely different combat style.

Here’s a build the devs highly recommend:

Quaker
Dark Pepper Soda
Decoy Bomb



This build is all about maximum satisfaction and pure exhilaration.
It just feels amazing to play.

Other options? Try the speed-maxed loadout featuring B-Fuse — it’s all about velocity and style.
With countless combinations, there's no end to the creativity you can bring to your battles.

So go ahead — find your favorite build, and make it your own!
We’d love to hear your thoughts and see what you come up with!
