Main Sequence: Release Date, Price & System Requirements

If you like the idea of starting with a tiny mining ship and eventually running an interstellar industrial empire, Main Sequence should be on your radar. Tumbling Dumpling Studio and publisher Mythwright are building a first-person space simulation and factory game where you design ships, build space stations, mine resources, research tech, and automate production. You can play solo or team up in co-op. It’s aimed at people who enjoy Factorio, Satisfactory, and space building games.

We’re sticking to what’s official as of October 20, 2026. If something hasn’t been announced, we’ll say so instead of pretending a guess is a fact.

 

Release Date

The Main Sequence release date is November 12, 2026. That’s when the game enters Steam Early Access. This is not the full 1.0 launch. The developers confirmed the date on October 1, 2026 through a Steam community announcement and a press release.

Early Access is expected to last around one to two years, though that can change as development moves along. The current Early Access build is said to include the core gameplay and main progression flow. The team plans to keep expanding building options, ship and space station modules, production lines, and exploration based on player feedback.

There’s also a free demo on Steam. That’s a smart way to see if the factory loop clicks before you spend anything.

SteamDB lists a planned unlock time of November 12, 2026 at 16:00 UTC. One important note: the developers have said the specific release time and other details will be announced later. So the table below is a reference based on that SteamDB record, not an official region by region schedule from the studio.

Region	Reference unlock time
Los Angeles, US	November 12, 08:00 PST
New York, US	November 12, 11:00 EST
United Kingdom	November 12, 16:00 GMT
France, Germany, Spain	November 12, 17:00 CET
Singapore, Hong Kong	November 13, 00:00 SGT / HKT
Japan	November 13, 01:00 JST

 

Main Sequence Price and Edition Comparison

Here’s the short version: there is no official Main Sequence price yet. As of October 20, 2026, the developers have not announced the final Early Access price. A Steam community post says price and exact unlock timing will come later. We also don’t have official USD or EUR pricing, so it’s better not to trust outside estimates as if they were confirmed.

The Main Sequence edition comparison is simple right now because there are no official multiple paid versions, deluxe editions, or ultimate editions. The clear split is between the free demo and the planned paid Early Access version.

Version	Price	What you get
Main Sequence Demo	Free on Steam	Starting galaxy, first two tech tiers, and basic ship upgrades
Main Sequence Early Access	Not announced yet	Fuller building, automation, exploration, combat, and progression content

The difference here is content scope, not confirmed paid tiers. The developers have also said the price will be adjusted when the game leaves Early Access and moves to 1.0, based on added content and progress. So if you see a “Main Sequence editions” chart somewhere, check whether it’s official before you believe it.

 

System Requirements

The Main Sequence system requirements are listed on the game’s Steam and Epic Games Store pages for Windows PC. The Steam page currently has full minimum specs. The recommended specs below come from the Epic Games Store demo page, so keep in mind that things may change when Early Access launches.

PC

Component	Minimum	Recommended
OS	Windows 10 64-bit	Windows 10 64-bit
Processor	Intel Core i5-8400 or equivalent	Intel Core i5-8400 or equivalent
Memory	8 GB RAM	16 GB RAM
Graphics	NVIDIA GTX 1050 or AMD RX 460	NVIDIA GTX 1050 or AMD RX 460
DirectX	Version 12	Version 12
Storage	5 GB available space	5 GB available space
Other	64-bit processor and operating system	64-bit processor and operating system

Those specs are pretty reasonable, but don’t carve them into stone. Early Access games can shift as optimization work continues.

PS and Xbox

Right now, the only confirmed platform is Windows PC. There is no official PlayStation 5, Xbox Series X|S, or other console version announcement, which means there are no official console system requirements to share. Don’t take the PC specs and assume they apply to a console version. That’s not how it works.

 

Conclusion

Main Sequence looks like a promising pick for players who want space factories, ship building, and co-op logistics without waiting for a full 1.0 release. The Main Sequence release date is November 12, 2026, and it’s coming to Steam Early Access. The demo is free, the final price is still under wraps, and the PC system requirements are modest enough that a lot of mid range machines should be fine. Console fans will have to wait for official news. For now, keep an eye on the Steam page and don’t buy into imaginary editions.
