Main Sequence FAQ: Is It on PS5 or Xbox, Price and Co-op

Main Sequence, a first-person space sim where you mine asteroids, design your own ships and stations and automate whole production lines across star systems, entered Early Access on Steam on 12 November. Developer Tumbling Dumpling Studio said it had passed 200,000 wishlists ahead of launch. Here's what's confirmed about platforms, price and co-op, and what isn't.

Update, 13 November: Main Sequence is out. The developer's "available now" post went up on Steam at 16:03 UTC on 12 November, and the 20% launch discount runs until 26 November ($19.99, £17.59 or €19.99). Early Steam reviews are Very Positive (85% of 80), and a first hotfix arrived on 13 November, fixing several bugs, including two in multiplayer. There's still no console version and no stated co-op player limit.

When did Main Sequence come out?

Main Sequence launched into Early Access on Steam on 12 November 2026. The developer never announced an exact time in advance; its "Main Sequence Available Now!" post went up on Steam at 16:03 UTC, which is 5:03pm in Paris and 8:03am on the US west coast. In Japan that was already 13 November.

Is Main Sequence on PS5 or Xbox?

No. Main Sequence is a PC game, and Steam lists Windows only. No PlayStation 5, Xbox or Switch version has been announced, and the developer hasn't mentioned consoles in any of its Steam announcements. Automaton reports that an Epic Games Store version is also planned, with no date yet.

How much does Main Sequence cost?

$24.99, €24.99 or £21.99. Until 26 November it's 20% off, so $19.99, €19.99 or £17.59, which matches the two-week launch discount the developer announced. There are also Steam bundles with other space and automation games, including X4: Foundations, shapez 2, Astrometica, Space Haven, Avorion and Astro Colony; if you already own one, you get a discount for completing the bundle.

The price won't stay there forever. Asked whether it will change after Early Access, the developer says on the Steam page that "the 1.0 price will be adjusted to reflect the game's progress and expanded content".

Does Main Sequence have co-op multiplayer?

Yes, online co-op. The Steam page says each player is the captain of their own ship, so you can split jobs (one on logistics, one on defence, one exploring) or work on the same goal together. You can also play the whole game solo. The developer hasn't stated a maximum number of players, and Steam lists online co-op only, with no split-screen.

Does Main Sequence have crossplay?

There's nothing to cross-play with yet. It's on Steam only for now, so everyone in your crew needs the Steam version.

Can I try Main Sequence for free?

Yes, the free demo is still on Steam. Since the Steam Next Fest update in October, it includes co-op, so you can test multiplayer with a friend before you buy.

How much content is in Early Access?

The developer says on the Steam page that the core mechanics and progression are fully playable, with around 40 hours of content. You start as a lone miner in an asteroid belt, build stations and factories with conveyor belts, set up automated supply routes between systems, trade with NPCs and fight an ancient alien defence network that wakes up as your industry grows. Star systems are procedurally generated, and there's a creative mode for designing ships freely.

Early Access is planned to last one to two years. The full version should add more building options, new modules for ships and stations, new production lines, more places to explore and possibly new factions.

Can my PC run Main Sequence?

Probably. The minimum spec on Steam is Windows 10 (64-bit), an Intel Core i5-8400, 8GB of RAM and an Nvidia GTX 1050 or AMD RX 460, with 5GB of storage and DirectX 12. No recommended spec has been published yet.
