About this game
WHAT IS "STARNAUT"?
"STARNAUT" is an easy-to-learn, hard-to-master "survivor-like" game that emphasizes massive Nitro Jumps and Dashes, evading with verticality, synergizing extremely powerful weapons, deep and considered lore, and of course, the strongest force in the universe....love!
Choose your 8 favourite weapons, and annihilate endless hordes of enemies! Feel the excitement of mowing down entire armies of the creeping terror known only as ZOL!
BE CAREFUL!! This game is way too addictive! Time flies when you're having fun!
Humanity is Extinct. Earth is Lost.
Copiasu, a designer baby created by two AIs, carries the final hopes of humanity. After Earth was torn apart by a multi-dimensional rift, he must dive into the multiverse and take on the mantle of Earth's final starfarer: Starnaut.
The Ω Rockets, holding Earth's final records, lie scattered throughout the space between dimensions. Finding and launching them all is the only path to Earth's rebirth! Driven by this hope, Starnaut forges ahead into the unknown multiverse, ready for anything!
NOTICE: Although this game features "gacha" as a plot element, it is NOT a "gacha game"!! Don't get it twisted!
The STARNAUT himself, and no one else, carries this torch burning bright, encoded inside his mind and in his heart, and to remember is to care, about each and every bit of it. Truly an enormous responsibility, by any measure.
He is a miracle, but he is still a person, same as you, who needs the love and support of others, and there are things about people that no circumstance can change....
Before the doomsday, people launched the Omega Rockets with thier precious memories and history but they ended up landing in multiverse!
Starnaut runs today to find out if all of the rockets were launched back, so the Earth will be ressurected. ...or not!?
Mission 1: Explore the Multiverse
Starnaut's unique power draws together distant realities through the multiverse, forming the stages where your battles unfold!
Over 60 diverse and exciting stages!. Clear them all!
Mission 2: Survive the Invasion
Take down swarms of invaders pouring from the multiverse! Some look cute, but don't be fooled!
Not an expert at shooters? No problem! Your weapons attack automatically!
Mission 3: Power Up with Coins
Defeated enemies drop coins!
Spend them at the Shopnaut for crucial weapon upgrades and power-ups during your run.
Mission 4: Launch Rockets and Get Oxygen
Launch 10 Ω Rockets to clear each stage!
They're also your lifeline, providing vital oxygen – activate them regularly to stay alive!
Mission 5: Collect Earth's data!
Hunt down elusive carriers holding fragments of Earth's "Lost Data." Punch them to retrieve these vital records!
Mission.... WHATEVER!! JUST BEAT EM AS MANY AS YOU CAN!!!!
Those enemies are not only hungry for you but YOUR KNUCKLE SANDWICH!!!
There are things like a gacha capsule, jump pad or even a hot spring!
Also, you can buy a new helmet and upgrade your spacesuit to enhance your basic abilities before you start the level.
Everything for you! Just use them well!!
STARNAUT, FIGHT SOLO! ANNIHILATE EM!
Tips for Getting Started
Remember: Defeat Enemies -> Collect Coins -> Visit Shopnaut!
Upgrade your weapons and suit to handle the escalating threats!
The Antenna weapon set is a great all-rounder when you're starting out!
Getting Armor or Auto-Recovery early on makes you harder to take down!
Once bought, weapons have infinite ammo and never break!
Don't ignore the tips from Wonderful coming through the antenna on your head!
Character
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.
Likes Toast when he’s late
Dislikes Solitude
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.
Likes Kaiten sushi
Dislikes Defeat
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.
Likes Ultimate weapons
Dislikes Being poor
Mouse/Keyboard and Controllers are supported.

Although *Starnaut* is a 3D game, this collaboration intentionally brings back a 2D-like presentation—with a few surprises that will make you go ‘Oh!’ Please look forward to it.”Luca Galante (Vampire Survivors Creator/poncle)I grew up playing with Takeyasu San beautiful characters and monsters. The fact that he enjoyed a game I made as far as he wanted to make an homage, I felt honored and very happy. I look forward working with him again.■ About Starnaut*Starnaut* is a 3D action roguelike game that follows Copias, a traveler journeying across multidimensional worlds in search of Earth’s revival.
