About Mythical Concept Starnaut
Mythical Concept Starnaut is a solo survivor-like game set in a multiverse where humanity is extinct and Earth has been lost. You play as Copiasu, a designer baby created by two AIs, who takes on the role of Earth's final starfarer, Starnaut. The Ω Rockets contain Earth's last records and are scattered between dimensions; finding and launching them is the route to Earth's possible rebirth.
Battle through the multiverse
Starnaut's power draws distant realities together to form battle stages. Across more than 60 stages, you fight swarms of invaders, including the creeping terror ZOL. Your weapons attack automatically, and you can choose eight weapons to take into battle. Nitro Jumps and Dashes let you evade attacks using vertical movement, while weapon combinations can create powerful synergies.
Upgrade and survive
Enemies drop coins that you can spend at Shopnaut during a run on weapon upgrades and power-ups. You can also buy a helmet and upgrade your spacesuit before starting a stage to improve your basic abilities. Weapons you have bought have unlimited ammunition and do not break. The Antenna weapon set is an all-round option, while Armor and Auto-Recovery can help you withstand attacks.
Each stage requires you to launch 10 Ω Rockets. They also provide oxygen, so you need to activate them regularly to stay alive. You can punch carriers to retrieve fragments of Earth's Lost Data, and encounter objects such as gacha capsules, jump pads and hot springs. Wonderful sends tips through the antenna on your head, and can sometimes be seen running around a stage with Lost Data.
Characters
- Copiasu: The eighth designer baby created by Stella, he fights with the dream of becoming a Starnaut and meeting her. Stella has already given him the title, but he is too shy to claim it. His positive nature drives him forward fearlessly; he likes toast when he is late and dislikes solitude.
- Stella: Copiasu's guide, originally created as the central AI brain of Seven Nights. When she emerges to the surface, she takes an automatically generated form that can vary slightly. She tries to maintain the form Copiasu first met and trusts as his beloved Stella, though she finds it chilly in winter. She likes kaiten sushi and dislikes defeat.
- Wonderful: An AI chatbot created after Stella, who once aided Copiasu and now supports him in his original chatbot form. His physical form sometimes appears on stages carrying Lost Data. He likes dry dorayaki and dislikes being ignored.
- Shopnaut: A silent, cool and nihilistic arms dealer who sells weapons when you have saved enough money. He is strict about money but can be unexpectedly kind, sometimes holding sales. He likes ultimate weapons and dislikes being poor.
