Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is 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?

“Hi! Thanks for checking out our early access release of Maia. Alpha access gives us the unique opportunity to work with the community and craft the game together. Maia is a game with unprecedented complexity, and developing features directly with our players allows us to refine these intricate game systems to create a world that really feels alive.”

Approximately how long will this game be in Early Access?

“We want to keep development hurtling forwards at a steady rate and plan to release update builds once a month as the game progresses. (You'll often see smaller updates go out sooner as we push out important fixes as soon as we have tested them.)

We just released 0.55! After that we will be releasing the campaign, extra single player maps and full modding tools over the coming months, whilst refining the game and adding greater depth to the content.”

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

“We plan for the full version of the game will have a complete single player campaign as well as the current sandbox mode. The campaign will last between 10-18 hours, depending on the player, but we expect the sandbox mode and additional single player maps (and of course mods) to give the player potentially endless replayability.”

What is the current state of the Early Access version?

“The game is still very deep in development, so many things might be broken. Sometimes in a rather amusing manner, sometimes... less so. The current sandbox build (0.57) has the core game play of colony building, colonist interaction and base simulation, the best is still to come.”

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

“We have priced the game at a reasonable price to avoid people impulse buying the game in it's early state. Once the campaign is in, and the community feels that we have hit the right level of quality, we will be raising the price to reflect it.”

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

“We try to read every forum post and email sent to us and work hard to consider and incorporate peoples feedback into the game.

You can follow updates and give us feedback on the game via Twitter on @Maia and on

On you can view changes going into the game in real time as we develop it.

0.61: A Maze Of Death

Maia 0.61 is out now. Right now. This build brings many new useful features to the game and a significant amount of tweaks and fixes.

Here’s a video of me playing the latest release:


This update brings several new user interface and management tools to the game. Room options are now available and allow for managing the stockpiling of items, new security features and even tweaking the lighting of a room. Just click a room to see the available options. Carefully managing these fine grained controls can significantly improve the efficiency of a busy base.

When placing items the UI now presents more useful information about whether an object is reachable, and visible paths are shown to illustrate how the colonists would walk to the item.

Movement orders

You can now practice your interior design skills and rearrange items in your base using the new movement order. By click-dragging on an item you will create a new move order and your colonists will push the items to their new locations. Utility robots given movement orders will use them as waypoints and if they are not too busy, go directly to the locations.

The tutorial has been significantly reworked and with more guidance and information, and provides an easier and clearer first contact with the game. Even experienced players may find it useful to give it another go.


Build priority changes for better base flow and design. Colonists are now more aware of the flow of a base and will order door builds based on the need of that specific room. They will also no longer have complete emotional breakdowns when locked in a room with no doors, so will build one if it is placed. They will also share workbenches more efficiently and the amount of duplicated builds has been reduced.

Suit refill points are now critical to surface operations. You can no longer build items far away from your base and must build a supply chain to the item so your colonists can restock their suits and rest.


Resuscitation and first aid has been added, allowing colonists to save unconscious members of the team (if they like them enough). Just ensure you pick some colonists with medical skills as improperly given resuscitation can give patients other health complications.

Other notable changes:
  • Colonists with surface walking skills will now walk much faster in suits.
  • Atmosphere generator output increased a little.
  • Vent system tweaked to push less air than the atmosphere generator.
  • Medical emergencies are now mentioned by the base announcer.
  • Probe generation fixed. Every map now has several lost robotic probes to find.
  • Tutorial spelling mistakes fixed.
  • Migration event emails now lock onto specific creature.
  • Camera locks on to colonist who sent an email when it is opened.
  • Utility robot infotip fixed.
  • If an AI is destroyed in code they will now properly release any item they were using.
  • Tutorial can now be completed using the alt-rotate.
  • Text overlays for objects and rooms are no longer drawn when an email is open.
  • Mouseover text is hidden if the player opens the manifest.
  • Cursor animations for left and right clicking.
  • Cursor size options added to the menu.
  • Capsules should no longer land next to each other.
  • Holes in several environment models fixed.
  • Fix for pathfinding bug where colonists went to wrong interaction point, potentially getting stuck.
  • Interface options menu split off.
  • Lights brighten when mouse-overed.
  • Tracking sound fixed to only fire when clicking a living item.
  • Sounds for selecting colonists on the menu added.
  • Sounds for turning on and off heaters fixed.
  • Fixed several colonist animation bugs.
  • General game code improvements and optimisations.
  • Inter-gameobject messaging improved code quality and to reduce bugs.
  • Engine render calls made more efficient.
  • Lava lights fixed.
  • Lava optimisations.

As you may be aware, we are rapidly approaching beta, so do send us all your bugs and issues. Be sure to get yourself on the development branch to see all the latest changes.

That's all for now. If you like these updates be sure to drop us feedback via Twitter and Steam reviews.

0.60 Love and Lava

Alpha 0.60 is here! Lava can now rain down into your base, incinerating anything in its path. Here's a video of me showing off the new features and changes to the game:

Lava, (perhaps more accurately, magma) is now in the game! Maps with high tectonic activity will run a huge risk of lava breaches, that will pour into your colony and destroy anything in its path. Watch as your equipment and colonists die gloriously in the all consuming fire. The system is a full 3d fluid smoothed particle hydrodynamics simulation so has realistically simulated viscosity, density and pressures all running in real time.

All intelligences in the game now have a detailed long term memory, allowing them to remember their actions, moods and feelings. In their emails, colonists will now comment on what they did in a day, why they did it, how they felt about it, how important it was and even details down to what the bases conditions were like at the time. Domestic and alien creatures will use their memory to make better choices in the future, such as returning to a place they found food or warmth.

Colonists can now make friends, build relationships, fall in love and make enemies. The relationships will change their attitudes towards each other, their moods and their behaviour in the base. New interactions, such as arguments, follwing and shoving will come about as colonists get to know each other.
Interface improvements
The game's zoom has been improved substantially to allow you to get in close to the action, and also to allow you to pull back for a wider overview of your colony.

Many small changes have been added to the user interface to improve object placement, such as wall-snapping auto-rotation of items and object-type rotation memory, to allow for consistent placement when placing several duplicate items. A small amount of latency has been reduced from the mouse movement which will also make things feel more responsive.

The new mission-day counter on the top right of the screen will give you a better feel for your base's progress as you track the passage of time.

Other notable Changes:
  • Plants can now be harvested earlier if needed. Priority is given to plants that are fully matured.
  • Colonist food preparation priority increased.
  • Extra detail added to colonist emails regarding food and base planning.
  • Pressing escape from the options menu now takes you back to the game.
  • IMP digging cancel requests no longer pop up if there are no dig orders.
  • Colonists can now request to disable the alarms for a short period of time.
  • Game window buffer swap now performed before the frame end sleep, to improve responsiveness.
  • Tweak for world gen to prevent jungle worlds!
  • If water need is higher than food need, the colonists may now eat to fulfil it too.
  • Colonist water need only hijacks food need if need is greater than 50%
  • Eating now gives a bit more water.
  • Solar arrays now correctly advertising food need to the vox nocturna.
  • Geothermal generator now repairable by robots.
  • Twilight Zone mission ending and some text fixed.
  • Colonists will no longer go outside without suits to shoot or inspect downed aliens.
  • Fix and tweaks for medical room items build priority.
  • Chance of leg or arm fracture from earthquake reduced down to 2% for each.
  • When choice to torch medical beds is given and dismissed colonists will only have a 25% chance of getting gastric distress instead of 100%.
  • Fix for geothermal generators causing colonists to go outside without suits on.
  • Sitting on the floor was not giving colonists enough rest. Therefore if you did not build colonists beds before they got tired your base would become very unmanageable.
  • Entire world object placement generation code updated. Must faster now, and you will always have some creatures on the map.
  • Colonists have a little more water in their bodies now.
  • Sweating reduced when dehydrated.
  • Sweating reduced to two litres per hour equivalent. If a colonist has one litres of sweat on their body, sweating now stops.
  • Fix for announcer bugs.
  • Food prep priorities tweaked a little bit.
  • Object destruction order priorities tweaked on many objects. Fossils are rarer. So less likely to jam up your storage room in the early game.
  • Gaps removed from emails.
  • Multithreading improved for systems with four or more cores.
As you may be aware, we are rapidly approaching beta, so do send us all your bugs and issues. The estimated date for the 1.0 release of Maia is now the end of May.

That's all for now. If you like these updates be sure to drop us feedback via Twitter and Steam reviews.

About This Game

About This Game

Maia is a strange and hostile alien world, toxic to humans, yet lush with new life. Your mission is to colonise this poison eden, survive it's dangers and establish humanity's first foothold in the stars. Created by independent developer Simon Roth, Maia is a space colony simulation game about surviving and thriving on another world.

Build your Base

Burrow into Maia's mineral rich crust to build and manage a complex base that fulfills your colonist's needs. They'll need somewhere to sleep, somewhere to build and a steady supply of food, water and energy.

An Enormous Procedurally-Generated World

Twelve light years from earth, the planet 3452C[Maia] circles Tau Ceti. Its atmosphere is toxic, its surface is ravaged by solar flares and meteor blasts and its unstable crust is constantly shifted by earthquakes. Nevertheless, it is theoretically habitable. Explore Maia through a series of vast procedurally generated mission areas, each one up to 2km by 2km in size.

Challenge Yourself

In addition to the sandbox mode players can take on four specific missions, with more to come in updates. Deal with an influx of refugees from a stricken space station in Cassiopeia, survive the perpetual night of arctic winter in The Twilight Zone, study Maia's local ecosystem in SN1572 and begin to terraform the planet in the shadow of an active volcano in Stratospheric Sulphates.

Research and Learn from the Planet to Survive

Maia is a hard science fiction game based on real or extrapolated technology. Some of the colonist's tools have been brought with them, but others must be fabricated from what they can find. Once your base is up and running colonists can begin to study the native environment researching new ways to use the flora and fauna of Maia to their advantage.

Dangerous Atmosphere

Maia's atmosphere is toxic to humans, so to keep safe you'll need carefully manage the atmosphere around your base with well placed airlocks, atmosphere generators, heaters and air vents. Air flow and heat circulation are realistically simulated, emulating the deadly challenge of surviving on an alien world.

Advanced Colonists AI

In Maia you don't have direct control of your colonists, they operate on their own initiative, fulfilling their wants and needs. You'll need to take care of both their bodies and minds if you want any of them to survive.

An Army of Robots

Colonising an alien world isn't something humanity can do alone, instead they've created robotic helpers to do the jobs they don't want to. The I.M.P. robot digs through Maia's crust and collects useful minerals, while the Utility Repair Robot takes care of all that routine maintenance humans can't be bothered with.

First Person Mode

Experience Maia through the eyes of your pet robots. Assume direct control and explore your base in first person, directly interacting with it by performing your robotic tasks. Become part of the world you've built.

Genetically Engineered Super Chickens

To survive, your colonists will need to create and manage new sources of food, thus the people of Earth designed the genetically engineered super chicken, the Uberhuhn. With enough time and diligent research you can even begin to collect and herd the native wildlife of Maia. Unfortunately most of it tastes terrible.

Custom Engine

Maia runs on a custom game engine made by independant developer Simon Roth. It is used exclusively in Maia and is purpose built specifically to support this game.

Immersive Soundtrack

Maia's immersive sci-fi soundtrack adapts and responds to in game events, ensuring it always reflects the mood of the game.

The Inspiration

Maia was inspired by games such as Dungeon Keeper, Theme Hospital and The Sims. It mixes strategy, management and construction with dark gallows humour about the many dangers of an alien world. Maia also draws from the retro future style of 1970s sci-fi.

To Come

  • A full story driven campaign, several hours long.
  • More rooms, and new base management systems.
  • Multiple bases.
  • More indigenous life forms and a functioning food chain.
  • Somewhat sassy computers.
  • Realistic water and lava simulation.
  • Cats with bee suits.
