Main Sequence early access price is £21.99 in the UK when the space-factory game launches on Steam on Thursday, 12 November 2026. Developer Tumbling Dumpling Studio and publisher Mythwright have also announced a 20% launch discount for the first two weeks, so buying straight away should cost less than the standard price.
If you’ve been building ships in the demo, the launch is more than a chance to buy the game. Early Access opens up a larger space-industrial sandbox, with asteroid mining, production lines, research and co-op exploration. Here’s what is confirmed about the launch, what the discount actually means and what you should check before purchasing.
Main Sequence early access price and launch discount
For UK buyers, the Main Sequence early access price starts at £21.99, while the announced US and euro prices are $24.99 and €24.99. Those are the normal Early Access prices, not amounts with the promotional reduction already applied. Mythwright says the introductory offer takes 20% off for two weeks after the Steam release.
Applying 20% to the announced UK base price gives approximately £17.59. That works out at roughly £17.59 before any regional checkout adjustments. Steam will show the exact launch price when sales open. The publisher hasn’t provided an exact discount-end minute, so anyone planning to purchase near the end of the offer should check the live Steam listing.
What you get on 12 November
Main Sequence begins with a mining ship in an asteroid belt. You scan for resources, extract materials, refine what you’ve gathered and expand into increasingly capable space stations. Production machines and conveyor belts turn a small operation into a system that can keep building while you explore elsewhere.
The larger goal is to design your own ships and stations, research new technology and expand into procedurally generated star systems. There are hazards beyond running out of useful materials: hostile alien defences, wrecks and unusual stellar phenomena give your industrial fleet something to prepare for. Both solo play and cooperative play are part of the Steam listing.
How long will the game stay in Early Access?
The developer estimates around 40 hours of Early Access content, although people who enjoy perfecting factory layouts could spend much longer. It isn’t a fixed campaign length. A player who spends evenings refining one supply route could easily approach the same content very differently from someone rushing through research.
Tumbling Dumpling Studio expects Early Access to last around one to two years. The schedule is an estimate, and the developer says the eventual version 1.0 price will be adjusted to reflect the expanded game. There’s no confirmed date for full release, and nothing official here establishes a console version or a precise Steam unlock hour.
Is there a demo, and does progress carry over?
Steam has a free Main Sequence demo, which received a substantial update for October’s Next Fest. That update added cooperative multiplayer, Electromagnetic Science research and equipment including the Shield Generator Mk. 1. It’s a useful way to see whether the mining and automation loop suits you before paying.
Mythwright has specifically said that demo progress will carry into the full game. You shouldn’t need to assume that you must restart everything from scratch on launch day. The publisher hasn’t detailed a separate import wizard or promised that progress can be moved between different Steam accounts, so avoid relying on either.
Main Sequence early access price and minimum PC requirements
Steam currently lists Windows 10 64-bit, 8 GB RAM, an Intel Core i5-8400 or equivalent processor, DirectX 12 and 5 GB of available storage among the minimum requirements. Its current graphics examples include the Nvidia GTX 1050 and AMD RX 460. Check Steam again before buying, as requirements can change during development.
When weighing up the Main Sequence early access price, think about whether you’re happy playing a factory builder while its features are still evolving. The 20% launch discount makes it cheaper to jump in now, but Early Access remains a work in progress. If you would rather play a finished game, there’s nothing wrong with waiting. The Main Sequence early access price is announced; Steam will show the final checkout amount and unlock status when sales open.
The Main Sequence early access price drops by 20% during the two-week launch offer. After that, the normal UK base price is £21.99 unless another sale applies.
