Main Sequence release date and launch status

This is not a 1.0 release. The developer plans an Early Access period of roughly one to two years, with the final length depending on when the game is complete and well-rounded. The store description explicitly warns that the game will change during development.

When does it unlock?

The publisher has not announced an exact unlock hour. SteamDB records a store timestamp of 16:00 UTC on November 12, 2026. That is a useful planning reference, not an official launch promise.

Use the launch timer to see that timestamp converted into your local time and a table of common time zones. The countdown on this page uses the same estimate.

Price: not announced

There is no official Main Sequence price. The October 1 release-date announcement said more information, including price and launch time, would follow. Third-party estimates are not confirmation.

The developer has confirmed that the eventual 1.0 price will be adjusted to reflect the finished game and expanded content. That means the Early Access price and the final price may differ. The store page does not currently list a price because the game is not yet available.

Platforms: Windows PC at launch

The official launch announcement names Steam Early Access. Steam lists Windows as the only supported operating system. No PlayStation, Xbox, Switch or macOS release has been announced, and we found no public statement about Steam Deck verification.

System requirements

Steam currently publishes a minimum specification only. The game is still in development, so treat these numbers as a baseline rather than a performance benchmark.

Steam currently publishes only the minimum specification. No separate recommended tier is listed there. The separate Steam demo lists the same minimum. We have not benchmarked a retail build because it is not yet available to the public.

What the requirements mean in practice

• 8 GB RAM: sufficient for the listed minimum. If you often play factory games with browser tabs or voice chat open, leaving more memory headroom is sensible, but do not treat that as an official requirement.
• GTX 1050 / RX 460 class: an entry-level dedicated GPU baseline. Integrated graphics are not listed.
• 5 GB storage: the listed install footprint. Patches and saves can add to this over time.
• DirectX 12: the game calls for Windows 10 64-bit or newer with DX12 support.

What Early Access means for this game

The developer’s Early Access statement says the core mechanics and progression are fully playable at launch: ship and station design, trading with NPCs, fighting alien enemies, factories and automation. The current store estimate is around 40 hours of content.

The 1.0 roadmap is not a dated checklist. The developer wants more building options, customization, quality-of-life features, factions, ship and station modules, production lines and exploration. We will not publish a fake roadmap with dates that have not been committed.

Demo save transfer

No official statement confirms that demo saves or builds will transfer to Early Access. If continuity matters, plan for a fresh start and preserve blueprints rather than assuming the demo state will carry over. This is still an unresolved question in the community.

Exact content at launch

The September 2026 playtest included later sectors, Cobalt and Graphite, a Trading Outpost and the Relic Destroyer, but playtest content is not a guarantee of launch content. The demo is a separate, limited slice. We label features as “demo” or “playtest” where the difference matters.
