Dyson Sphere Program is a planned factory simulation game created by Youthcat Studio and released by Gamera Games. It became available in early access in January 2021 for Windows on Steam and WeGame.
Players are responsible for gathering resources to build a growing network of automated factories that span many stars. The goal is to provide power to a supercomputer and eventually construct a Dyson sphere. The early access version has received mostly good reviews, with many praising the game's mechanics and visuals. However, some players have noted that the beginning of the game and the user interface could be improved. The game has been compared favorably to similar titles, such as Factorio and Satisfactory.
Gameplay
Dyson Sphere Program is a game where players build and manage factories in a science fiction world. In this setting, human thoughts are turned into digital data and stored in a powerful computer called the "Centrebrain." The player controls a customizable robot named "Icarus," sent by a group called "COSMO" to an alien planet. The mission is to build structures that generate energy for the Centrebrain. To achieve this, players must create a network of factories across space to collect minerals from nearby planets. The ultimate goal is to build a Dyson sphere, a structure that surrounds a star to capture all its energy.
Factories include machines that collect resources, electrical systems, and assembly lines connected by conveyor belts. Players start by gathering materials like stone, iron ore, and copper manually. As the game progresses, they build automated systems to collect, refine, and produce components, structures, and items. Efficient factory layouts are encouraged to reduce manual work and improve resource flow. Buildings can be removed and rebuilt to redesign factories. All structures require power from sources like wind turbines, solar panels, thermal plants, or artificial stars. The robot, Icarus, needs fuel such as plants or hydrogen.
Special items called "matrices" are made in research labs, which help players advance through a technology tree. This allows upgrades and unlocks new structures and abilities to expand and automate the factory. Upgrading Icarus enables travel to other planets and stars to gather rare resources. Drones transport resources between factories across the galaxy, allowing large-scale industrial operations. The game continues until the Dyson sphere is built and launched into orbit.
With the "Rise of the Dark Fog" update, players must also defend their factories from attacks by a hostile group called the "Dark Fog." Structures like turrets and energy shields can be built to protect against these attacks.
Development
Dyson Sphere Program was created by Youthcat Studio, a team of five people based in Chongqing, China. The studio was started by Mao Mao, who graduated from Chongqing University, and Zhou Xun, who already worked in the game industry. Mao Mao and Zhou Xun met before and shared an interest in science fiction. They got ideas from the space-themed game Stellaris, which included building Dyson spheres as part of its gameplay. They planned a game about constructing a Dyson sphere step by step. Inspired by the 2019 Chinese science-fiction movie The Wandering Earth, Mao Mao and Zhou Xun began working on their game concept in April 2019. They spent several months making early models of the game before deciding to work on it full-time. Zhou Xun left his job to form Youthcat Studio with Mao Mao and hired three more developers to help. The project was funded with money from Zhou Xun’s savings, giving them up to two years to prepare the game for release. Near the end of the two-year period in mid-2020, they met with Gamera Games, a Chinese publisher that helps small game teams. Gamera Games helped Youthcat plan an international release of the game and hired voice actors who had appeared in The Wandering Earth to work on the game.
The National Press and Publication Administration of China approved Dyson Sphere Program on September 21, 2020. The game was released in early access on Steam and WeGame on January 21, 2021. Youthcat Studio planned to spend about a year improving the game during the early access period before considering it complete. In January 2022, the game received an update that let players change how their mecha looked. In December 2023, the “Rise of the Dark Fog” update introduced a non-player character (NPC) enemy group that attacks the player’s factories regularly. The update also added structures players can build to protect their factories. Other updates included customizable keyboard shortcuts and better tools for building.
Reception
Youthcat reported selling more than 200,000 copies within four days of entering early access. By the end of the first week, sales reached over 350,000 copies. The game was the most popular on Steam during its debut week. By September 2021, total sales had grown to more than 1.7 million units.
The early access version of Dyson Sphere Program received mostly positive feedback and was compared to other factory simulation games, such as Factorio and Satisfactory. PC Gamer described the game as "very well made" for an early access title. Rock Paper Shotgun noted issues with the user interface but praised the graphics and real-time lighting. They included Dyson Sphere Program in their list of favorite games for 2021 and called it "a must-play for fans of factory games." Polygon highlighted the enjoyable experience of building and redesigning efficient factories but mentioned that setting up the factory initially involved many repetitive tasks. GameSpot added the game to their list of best sandbox games in 2025.
