Introducing Main Sequence

All newsPlayers around this dateRead on Steam

Welcome aboard Commanders!

I'm Kaiden, the solo developer of Main Sequence, here to report on the state of the game.

For the past couple months, I've been focusing on polishing the demo for a September 2025 release, with a specific date TBA. Development has really been picking up recently, and there's a lot I'm excited to share.

Core Gameplay Loop

The first step of any factory game is gathering resources. In Main Sequence, there are two ways to do this: mining asteroids with your ship, and building mining drone bays on stations. You can build out your ships and stations with as many of these as you like, provided you have enough power to run them. This lets you significantly scale your mining operations even in the early game.

The Designer is where you build and expand your ships and stations. In game, you can access the designer either in the Command module to edit your station, or in the Shipyard module to edit the ship you’ve docked there. You can also access the designer from the main menu, where you can design in creative mode and save your blueprints for later.

Once you’ve built your first station, you’ll be able to build Machines to automate refining and crafting. You’ll have to expand your station to fit more and more machines and solve logistics problems to make sure every item ends up where it needs to be.

The core progression is through Research. Certain items you manufacture can be fed into Science Labs and converted into research to unlock new technologies. These include new crafting recipes, new machines, and new modules for your ships and stations. Right now, there are a few initial technologies available to unlock for each category and more will be added as development continues.

What’s Next

If you’re interested in checking out the game as soon as possible, the next round of playtesting will start on August 15th so sign up to get notified. This will be the last round of playtesting before the demo release. The demo will feature the first solar system and the first tier of technology, as well as full access to the creative designer.

If that sounds interesting to you then make sure to add Main Sequence to your wishlist to get notified when the demo releases. You can also check out our Discord to see what other people are building and get more frequent development updates.

Cheers!

Kaiden
