- Playtest Week - 9 September 2026
Greetings Commanders!Since the launch of the demo I’ve been busy working on lots of new content and improvements. It’s been a year now since the first playtest. Getting your feedback has always been the best way to improve the game, that’s why we are running another playtest for Main Sequence starting next week on September 17th.Playtest WeekUnlike the playtest last year, this playtest is only going to be available from September 17th to September 25th. During that time you’ll have access to the full content of the game, and I’m excited to see how far you make it in a week.The demo will remain available during that time and so to access the playtest you will have to sign up separately, and it will appear as its own app in your Steam library. If you have signed up for the previous playtest, you won’t get a notification when it goes live so make sure to check your Steam library on the 17t…
- Thank You for 100 000 Wishlists! - 9 June 2026
Greetings Commanders!It has been almost 2 weeks since the Demo went live, and it's been great to see so many players both returning from the playtest and checking out Main Sequence for the first time. Thanks to your support, Main Sequence now has more than 100 000 wishlists!It has been great to see lots of new feedback for the Demo. Because Main Sequence combines many genres, as the game reaches new players there are many different expectations for what kind of game Main Sequence is and can be. Being able to customize your experience in Main Sequence so that you can focus on the parts of the game that you enjoy the most is something that I will keep working on for the Early Access release. Some of these features, such as peaceful mode, are already in the demo and there will be more to come to scale the difficulty of things such as combat, research and automation requirements.Thanks agai…

- Main Sequence in 2026 - 19 January 2026
Greetings Commanders!It’s been a while since the last update, but the development of Main Sequence has been moving along at a steady pace behind the scenes. There were a lot of exciting milestones for Main Sequence in 2025 which I’ll highlight in this post, as well as give you an idea as to what to expect from Main Sequence in 2026. Public PlaytestThe biggest milestone of 2025 was the release of the public playtest back in August. The interest in the playtest far exceeded my expectations, and it has been great to see so many people enjoying the game even in this early stage. A big thanks especially to all of the creators and streamers who covered the playtest. Not only does it help share the game with new audiences, it is super helpful as a developer to see the live playthroughs and reactions of people checking out the game for the first time. The playtest highlighted some key issues as…
- Introducing Main Sequence - 12 August 2025
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 LoopThe 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…
