London, UK – September 17, 2026 – Lift off to the frontier of space to forge an interstellar empire in a major new playtest for first-person space-sim factory builder Main Sequence, available to download today on Steam.
Featuring the full work-in-progress version of the game, the Main Sequence playtest provides the most extensive look at the game yet, with dozens of hours of content to explore as pioneers set out to expand humanity’s footprint amongst the stars.
Starting out with a single mining ship in a resource-rich asteroid belt, embark on a voyage across space to collect and refine materials, build your factory, research new technologies, and reach new frontiers.
Explore the galaxy as a solo voyager or team up in co-op, travelling to the edge of the solar system and beyond to expand your industrial operation. Research advanced technologies to reach distant star systems and locate deep-space resources, building your ship and space station module-by-module as you venture into the unknown.
Discover abandoned space stations, engage in thrilling deep space combat, automate your ever-expanding facilities, and leave your mark on the galaxy in a resource management and factory sim set across the vastness of space.
The Main Sequence playtest is available to download and play on Steam today until September 25th, ahead of the game’s Early Access launch later this year.
