What the developers have to say:

Why Early Access?

It is important that you consider the information below before deciding if you want to support Astroneer this early:

Astroneer is an incomplete game that is in currently in Alpha.

Astroneer will be in Early Access on Steam so that we may get the game in the hands of players as soon as possible. Engaging with the Astroneer community is extremely important to System Era, as we want to work closely with our players to make Astroneer the best aerospace and planetary exploration experience ever.

Since the game is in active development, Astroneer may have bugs, crashes, multiplayer instability, performance issues and so on. This is part of the development process and while we will try our best to keep the experience as stable as possible, rapid live development can cause issues at any moment. Supporting Astroneer this early allows us to develop the game with player feedback, and that feedback will ultimately shape the future of the game.”

Approximately how long will this game be in Early Access?

“It is hard to estimate exactly how long Astroneer will be in Early Access, though we are aiming to release the 1.0 version with free post launch updates in 2018.”

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

“The full version of Astroneer will be the complete aerospace exploration fantasy.

  • Explore infinitely diverse worlds with unique atmospheres, biomes, and landscapes.
  • Shape your world with a myriad of deformation tools and features
  • Survive against a number of hazards, ranging from weather situations, aggressive flora, and environmental effects.
  • Build and manage a working industrial base and leave your fingerprint on the galaxy’s economy.
  • Customize everything. Change what your Astroneer looks like, choose the base layout you want, and customize your vehicles for specific roles.
  • Play with friends in an online experience that encourages communication and cooperation to succeed, or play on a dedicated server that could contain friends and strangers.
  • Unravel the mysteries of the galaxy as you search for the elusive rare items.

What is the current state of the Early Access version?

“The current version of Astroneer is changing rapidly while we implement new systems to the gameplay experience. After spending the Pre-Alpha period exploring, prototyping, and scoping out the final version of the game, we are now in full on content development. Expect to see new features/content rolled into the experience every update. For details about what we have coming, see the below section about Alpha!”

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

“Astroneer launched at a low price considering how early in development the game was. As the game matures and its content grows the price of the game will be reviewed.”

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

“System Era will work with the community to ensure Astroneer is the best fantasy it can be through a number of ways: Our own forum, Steam Community forums, our blog, Twitter, Youtube, and Facebook. System Era aims to be as transparent with the game’s development as possible so that its community can be as equally transparent with us with how they're feeling about the game and share the improvements they would like to see. We post regular updates on youtube showing off what the team is working on!

Basebuilding Update Live!

Steam 'Early Access' users will receive this update today, Thursday February 22nd, 2018.

The Basebuilding update is Astroneer's biggest update to date. Whether underground, on a mountaintop, or on far away planets, the all new Basebuilding and Power systems will allow you to create efficient bases that are all your own. This update includes 20+ new art pieces, which includes new platforms, modules, items to print, and much more. With that being said, this update is only the beginning for Basebuilding as a system. We have already begun development on more features and content to continue growing the already robust foundation. Check out the basebuilding trailer below!

You will find these updates in, the current build of the game.

Introduction of the Basebuilding System

Creating bases has changed fundamentally at its core. Now Astroneers can create bases however they like with a variety of new movable platforms and new ways to connect those platforms together.

We have introduced free standing movable base platforms. Three all new Platforms have been added. Two versions of the Medium Platform, and a platform for base modules, the Large Platform. These objects can now be placed and rotated individually, allowing for greater flexibility in base configurations. Lock platforms into place by connecting them to power. If you want to move them again, just disconnect all power lines.

Introducing: Fabricators. Fabricators are portable printers that allow you to make bases. Pop up the new control panel, pick what you want to fabricate, and in the end you will have a crate you can unpack immediately or bring with you anywhere you go. The Small Fabricator allows you to bootstrap an entire base from your Backpack and is used to print Medium Platforms and Medium Fabricators. The Medium Fabricator is for printing Large Platforms and Base Modules. Medium Printers and Vehicle Bays remain unchanged for now.

The starting Habitat module has received a visual update. Complete with a built in Oxygenator, Power Generation System, nighttime running lights, and 4 power connectors, the new Habitat is top of the line Exo Dynamics technology.

All printed base Modules and Platforms now come in the form of packaged crates. This allows them them to be moved or stored before deploying. Hovering over a crate on the ground or a Module on a Platform will show a hologram preview of its orientation. Base module crates can only be unpacked while on top of a platform, so keep that in mind when planning your base.

Added a new Landing Pad which automatically deploys next to a new Habitat. The Landing Pad is used to call in your first packaged items, and as zone for other players who join your session to land. Be aware that calling in new packages to the landing pad will destroy the extant ones. We plan on adding more functionality to the landing pad in the future. For now, shuttles will still land in the area in front of a vehicle bay.

Bases created in previous builds will automatically migrate to the new Basebuilding system. When loading into an old save, Platforms and Modules will be converted to their movable, packaged form. We tried to support old saves as best we could so there was no loss of items, but terrain might not always generate properly. As always though, use old saves at your own risk.

All holograms have received a visual update. They should now be much more readable at all times of day.

The introductory landing sequence has been updated. We will continue to improve on the introductory sequence in future updates.

Implemented an all new Power System

Changed the Power System over to a system that uses streaming shared power pools. That means items that need power pull from available power generators on a connected network. All Modules, Rovers, and crashed solar arrays have been migrated to use this new power system. To see how a network is doing, check out the new power indicators on platforms.

Cable and Cable Connector Art has been updated. Cables and their Connectors are now indicators for how much power is running through a network. When the indicator is red, the network needs power and all Modules connected to it will not run at optimal efficiency. As you add more power, the indicator will begin to expand, and connected Modules will run faster.

Added a new directional power tool, Extenders. Extenders are printable in bundles of six from your backpack. Extenders provide directed power flow, which redirects excess power from one pool to another. Drag a cable from the extender to indicate the direction of power and where you would like it to flow. Power flow is indicated by the large chevron on the cable.

Added small standalone platforms for small power items. When placed on the ground, Small Solar Panels, Small Generators, Small Wind Vanes. and Worklights will now deploy standalone bases with two Power Connectors on them. Use these to add power to your network, power bespoke standalone platforms, or as extenders that also add power. Small worklight bases also contain spikes can now stick to any terrain surface regardless of orientation.

Interaction Updates

A new interaction verb “Use” has been added to the game. Holding Use (by default E on keyboard and X on the Gamepad) triggers using an object. It is also used to get in and out of vehicles and the Habitat.

A new interaction verb “Examine” has been added to the game. Holding Examine (by default Q on keyboard and Y on the Gamepad) triggers examining an object or its control panel.

Holding Q on keyboard or Y on Gamepad will now open the Catalog whether or not the Backpack is open. This is a change from the double-Q / double-Y interaction from previous releases.

  • Shoulder buttons can now toggle items in the Backpack Auxiliary slots on and off.
  • Interactions that need to be held rather than tapped, like Use and Examine, now have a visual indicator ring around them.
  • Platforms and Modules can be rotated using Z / X keyboard and RB / LB on Gamepad by default.
  • When standing close enough to power slots, Gamepad users will auto-select slots that can pull connections.
  • The Backpack printer can now be used with the directional pad and A button, rather than having to use the Gamepad cursor.

Other Updates
  • Small Generators now auto-pull nearby Organic resources when actively generating power.
  • Small Generators will now automatically turn on when an Organic resource is added.
  • Firework rocket has been added to the Catalog as an unlockable object. Happy Lunar New Year!
  • Control Panel buttons, including the Research Platform, have been updated to change color and icon depending on whether pressing it will start, stop, or cancel a process, or if there is insufficient power.
  • Tutorial help menu carousel has been updated to include Basebuilding, Power, and Interaction changes.
  • Informational widgets that appear at the bottom of the screen have received updated visuals.
  • Optimized rendering of hovering info text that appears over holograms, along with other minor framerate optimizations.
  • Made several changes to the gravity system to improve stability of Rovers.
  • Medium Generators now provide about 30% more power

If you want to see the other stuff that happened this month that didn't make it, check out our vlogs for weekly insight to what the team is doing.


  • Fixed several issues causing Rovers to float when outside of physics range. There should now be fewer instances of Rovers going on a beautiful journey into space.
  • Unified the simulation of the vehicle chain. This should mean many less vehicle physics freakouts going forward.
  • Fixed an Xbox One crash that sometimes occurred when players were transitioning into Multiplayer games, improving overall stability.
  • Fixed a PC crash that sometimes occurred when players were transitioning into Multiplayer games, improving overall stability.
  • Fixed a minor issue where large rocks would not despawn when dislodged, causing untidy bases.
  • Fixed an occasional bug where the mouselook camera would do a single wild 360 degree swing.
  • Fixed an issue where players were sometimes able to pick up things inappropriately while seated.


The following major features are continuing during development, but are not included in this release. Now that we are in Alpha, you can expect to see all of these items implemented during the first half of 2018. Click here to see the full roadmap.

Dedicated Servers - (Q2 2018)
We now have our final plan for implementation and player workflow when it comes to dedicated servers and have begun implementation. The rollout plan is to have servers provided through a 3rd party during Early Access for stress testing, and then DIY hosted servers at a later date.

Basebuilding - Implemented & In Progress
Its finally out! As mentioned above, we still have plenty more we want to add to this system. We would love your feedback once you get your hands on it.

Research 2.1* - Implemented & In Progress
The next steps include working on items that instantly grant you research points, and unlockable blueprints that can only be found out in the world and never be unlocked via the catalog. Expect this to keep getting more content for our next few updates.

Weather and Hazards - (Q2 2018)
As a part of Terrain 2.0 we will also be introducing an entirely new weather and hazard system to challenge players. First on the list is fixing the wind system so it is more predictable and players can rely on it as a source of power generation.

Terrain 2.0 - (Q2 2018)
Not much has changed here. The terrain system is now stood up, and final tools are being implemented to account for item placement in the world. Adam has begun generation of terrain and exploration of new planets and biomes.

Thanks for reading all of this! Really excited to get these sweeping changes into the hands of players.

Patch 0.5.1 Live!

Steam 'Early Access' users will receive this update today, Wednesday January 17th, 2018.

This update is a followup to the Research Update! The team took some much needed time off for the holidays and were going to hold off on updating till February, but decided to keep to the "update every month" schedule to spend time fixing some bigger crash bugs and add another feature to the Research system!

You can find these updates in, the current build of the game.

Research System now uses Multi-Phase rates
This release we've made a big update to the research system that debuted in our last update. Now every research subject contains multiple phases with different Byte values. Some items have their most valuable phase early, some much later, and some in between. So if you really want to maximize your research operations, you have lots of new decisions to make about what to research, when, and for how long. To help you make these decisions and figure out how much you want to min-max as a player, the Control Panel on the Research Chamber now shows a timeline of all the current item's phases.

If your current research subject has moved into a lower-rate phase, and want to replace it something that's higher value, you can stop the current research operation and and load in the new subject right away. But be careful, stopping a research operation early means sacrificing any uncollected points! So don't be reckless, okay?

Update to the lighting system has been implemented
In this patch we included an overhaul to the lighting system. The main goal was to get the game running using the ACES tone mapper, so we could then get the game running in HDR in a future update. That meant spending lots of time recreating the look of Astroneer in a completely new system. We aren't completely done tweaking this, but overall this approach is a huge step in the right direction.

If you want to see the other stuff that happened this month, check out our vlogs for weekly insight to what the team is doing. The most recent one shows off the new Basebuilding system:


  • [AS-1522] - Fixed a number of issues that were causing save files to be deleted when the game crashed or the application was closed. In the most common case, this occurred when very large saves took enough time to write out that the user had time to close the window before the file finished.
  • [AS-1958] - Fixed an issue causing inconsistent playback of Gas Hazard audio
  • [AS-2097] - Fixed a minor issue where the Astroneer could still walk around when scrolling through the pages of the Help screen.
  • [AS-2104] - Fixed an annoying Multiplayer bug which prevented the Client player from exiting a flipped vehicle in Multiplayer games.
  • [AS-2113] - By adjusting a few things in the engineering team’s favorite part of the code, local wind effects should now only spawn for the relevant player rather than all players in a Multiplayer game.
  • [AS-2158] - Fixed a bug where the Research platform remained in the "completed" state if it lost power while in that state.
  • [AS-2172] - Base platforms no longer have "ghost" slots on the front that store only Compound. Goodbye, secret Compound storage.
With automated crash reporting coming online last month, during this release cycle we focused on fixing some of our most common crashes. There are a dozen or so more, but are pretty technical so I tried to summarize them here.
  • [AS-2148] - Fixed a crash that occurred when entering the pause menu
  • [AS-2150] - Fixed a crash that occurred while printing an item
  • [AS-2153] - Fixed a crash that occurred while opening your backpack in certain situations
  • [AS-2155] - Fixed a crash that occurred while loading a save game

We just completed a comprehensive overhaul to the roadmap! Now you can see projected time frames for upcoming content, as well as our ideas for free post launch content. The following major features are continuing during development, but are not included in this release.

Dedicated Servers
We currently have a dedicated server running with a third party that we can connect to. There are plenty of bugs still yet to deal with, but we are getting closer and closer to public launch.

We have already completed a couple of playtests, but this is feeling really great right now. If you watched the above vlog, you can catch some glimpses of basebuilding in action, but here is an image that Spencer made during one of our recent playtests that sums up a lot:

(none of the above art is final*)

Research - Implemented & In Progress

We just keep going! This update As with all of the new systems we are shipping, these are just base implementations that we will now work on expanding. Multi Phase items are now in, and the next steps include working on items that instantly grant you research points, and unlockable blueprints that can only be found out in the world and never be unlocked via the catalog. Expect this to keep getting more content for our next few updates.

Terrain 2.0, Weather, and Hazards

This is still in a similar place as last update. Zabir is working hard on ironing out some of the last authoring tools that the art team will use to create planets, biomes, and weather. The next step here will be generating one of the existing playable planets with the new system for testing!

Also, the first versions of aggressive flora were shown off in the last vlog. We are now working on making variations that utilize some of the cool behaviors Andrew created.

Thanks for reading! Stay tuned for details of our next update, which will probably be our biggest one to date!

About This Game

Explore and reshape distant worlds! Astroneer is set during a 25th century gold rush where players must explore the frontiers of outer space, risking their lives in harsh environments for the chance of striking it rich.

On this adventure, a player’s most useful tool is their ability to shape their world, altering the terrain and extracting valuable resources from planets, and moons. Resources can be traded or crafted into new tools, vehicles, and modules to create everything from massive industrial bases to mobile rover bases.

  • Reshape terrain as though it were made of Play-Doh.
  • Survive on and explore procedurally generated planets that can be entirely deformed and traversed.
  • Build vehicles and travel to new planets and moons.
  • Snap together components and objects to create custom vehicles and modules.
  • 4 player online drop-in/drop-out co-op.

What does this mean? It means that Astroneer is still very early in to its development. We've designed Astroneer from the ground-up to be a game that is developed in Early Access. When you first play the game, you will notice that the core gameplay is there but that we have a lot of work ahead of us. Now that we have moved to Alpha, you can expect the following content in the next few months:

  • Basebuilding: This system will allow for completely customizable base layouts that can be modified and moved at any time. (Q1 2018)
  • Power Refactor: Power management will become a completely new gameplay experience, players will have the flexibility to layout base infrastructure however they wish. Want to harness the power of the sun but create your base underground, hidden from the harsh weather on the surface? Create a solar farm and run cables down to your subterranean base. (Q1 2018)
  • Terrain 2.0: An all new procedural terrain system that will be much more performance friendly, while allowing us to create much more robust planets. These new planets will include more diverse biomes, land features, underground cave systems and more. (Q2 2018)
  • Weather & Hazards: A completely new system to challenge players when exploring or while at their base. Deal with environmental effects while in the relative safety of your base, or explore planets while outsmarting aggressive flora. (Q1 2018)
  • Dedicated Server Support: (Q2 2018)

In addition to the features mentioned above, you can expect a game like Astroneer in Alpha to contain bugs, crashes, and overall instability in single and multiplayer.

If you think our core gameplay is compelling enough to want to support Astroneer while it’s still in Early Access, we'd love to have your support. Otherwise, we recommend waiting until Astroneer is out of Alpha and in a state where the game is more stable and gameplay and content are further along. We're committed to making Astroneer the best it can be and including you this early in to its development is a crucial step that that.

If you're curious about the direction we're aiming to take Astroneer in, be sure to go check out our road map, and our development vlogs that we post a couple times a month!
