Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Early Access is the best way to realize the full potential of Main Sequence, as it allows the game to evolve based on feedback from the community. Making the game available in Early Access means that players can help shape each update along the journey, which ultimately makes the game more balanced, engaging, and enjoyable.”

Approximately how long will this game be in Early Access?

“The plan is for Early Access to last 1 to 2 years, with the most important factor being that the game is a complete and well-rounded experience when it leaves Early Access.”

How is the full version planned to differ from the Early Access version?

“For the full version of Main Sequence we plan to have more building options and customization, as well as quality-of-life features. This could include new factions, new modules for ships and stations, and new production lines. We plan on expanding the world with more places to explore, things to discover, and characters to meet.”

What is the current state of the Early Access version?

“The core mechanics and progression are fully playable, where you start as a humble miner and build up an interstellar logistics empire. You can design space ships and space stations, with lots of options for both functionality and decoration. You can trade with NPCs and fight alien enemies. And of course you can build massive factories, and automate everything in the game so far. There is currently around 40 hours of content, though fans of automation will hopefully find these systems deep enough to offer many more hours than that.”

Will the game be priced differently during and after Early Access?

“Yes, the 1.0 price will be adjusted to reflect the game’s progress and expanded content.”

How are you planning on involving the Community in your development process?

“The creations that players share are awesome to see and play a big role in informing the development process. There are also direct channels for feedback built into the game, as well as ways to engage with the community on Steam and Discord where we are active. Gathering feedback and engaging with the community is at the core of Early Access so as new opportunities come up those will be explored as well.”

About This Game

You are at the frontier of human-charted space in a small mining ship, tasked with expanding humanity's footprint amongst the stars. To succeed, you’ll need to collect resources, automate production, expand your base of operations, and research new technologies.

You start out with a single mining ship in a resource-rich asteroid belt. Use your scanners to find the best places to mine, and then refine the resources on your ship. Build a space station to set up a permanent base of operations which you can begin to expand and automate.

Onboard your stations, the factories you build are the heart of your industrial operation. Build machines, connect them with conveyor belts, and plan your production lines to keep everything flowing at full efficiency. Once that's running, that same logic extends across systems - automated supply routes between stations, and a fleet that keeps everything provisioned while you focus on expanding your operations.

Every ship and station is yours to design, inside and out. Module by module, you decide cargo capacity, reactor placement and weapons - whatever the situation calls for. Save designs to use again, share them with friends, or build freely in creative mode.

You'll need those weapons. Your industrial activity has woken something up - an ancient alien defence network that's identified you as a threat . Use your fleet to protect what you've built, or take the fight to them before the next wave arrives.

Research new technology with the items you produce. Each unlock opens up new ships, station modules, items and upgrades - everything you need to push further out. You will need to expand your industrial operations into new frontiers, but each new area will bring its own challenges and enemies to overcome. Use all of the tools at your disposal to build the ultimate battleship capable of handling any threat on your path to victory.

Venture into the unknown, with each procedurally generated star system offering unique logistic challenges to overcome. Explore wrecks, find new resources, and discover stellar phenomena such as black holes and neutron stars. Meet allies along the way as you uncover the different factions within humanity, and choose who to help as you build your legacy amongst the stars.

Play solo, or in co-op where each player is the captain of their own ship. Divide responsibilities however you like - one on logistics, another on defence, another out exploring - or work side by side on the same objective. Co-op opens up what’s possible. The bigger the crew, the bigger the empire.
