EA4 Release - electricity patch


A brand new update is now available on Steam: the Early Access Update 4 (version

In this update:

You'll find:

- Lots of new electrical boxes! Which brings a billion possibilities! We can't wait to see your creations! On our side, we will use these mechanisms to animate our donjon and create enigma.

- Welcome the "mini planets" A few modifications in our engine were necessary, but it's finally done! Now, we handmake those little planets and use them in the story mode. Those planets will soon be used for some key points in the adventure!  



- Welcome the Avis planet, directly linked to the "Stellar Overload". All the revelations on this planet will only be revealed in the story mode, (as and when release come out) don't try to make us talk!  

A new wallpaper on Aevis is available here

All the details of this update here.

The following of the story plot is asking us a little bit more effort than planned. We actually wanted to improve some gameplay elements (your feedbacks were very useful!). The dedicated server is not totally stable yet, but we solved the main problems. It should be out for the next update.

Early Access Update 3, let's go!



We are more than happy to present the new update ( of Stellar Overload!

Find below the list of the main new features available in this update.  



A brand-new feature has been added to the game: electricity!  

In this very first version, you can have fun with switches, cables, batteries, doors, lasers, NOT gates and AND gates. 

To be more specific, we chose to separate logic and power supply. You have to handle both systems at the same time:  

  • Be sure supply power to your items with batteries and powercables (otherwise they may not function that well). 
  • Control your items with switches through logical cables.

You can have more information in game pressing F1 (or TAB), we added a specific part in the codex for the electricity.  


A new type of vehicle is coming: a motor on a rail. We decided to call it "Motorail"! To function, it has to be connected to a battery and to at least one switch…  

Those two elements (motorail and electricity) can seem pretty trivial but it actually multiply the creative potential of the game.

We cannot wait to see what you’ll do with it!  

The HookBlade  

It’s been a while since you have been asking us to add melee weapons. There you are: there is a blade in the game! At the same time, we added a functionality to it: the grapple. The grapple allows the player to have more mobility. 

You will find the Hookblade in the inventory in the creative mode (use the new “weapon” filter). In story mode, you’ll find it during your adventure. 

For now, the grapple only functions on walls. But we are planning on improving its uses and making it possible to target enemies.

Novo Ares

An update = a new planet. This time, we progressed pretty well on the Novo Ares planet.

Novo Ares is a very specific planet: very arid in the surface and tropical at the bottom of its canyons.

 Syntonized Stellarium Lab 

Here is the true dungeon of Merx: the Syntonized Stellarium Lab. Robots took over an ancient human lab where humans did some research on Stellarium. Stellarium is a material about which we do not know much. We have to take back this lab! 

Do not look for the old fortress, we erased it from the game.

Other interesting functions 

  • Share universes on Steam Workshop

Did you create a big dungeon? You can now share it worldwide! Everything happens on the universe loading screen. 

  • Hunger

You asked for it, it finally is in game. Some items now restore hunger, others restore life. 

  • Difficulty levels

When creating a game (or loading it), you can now configure several difficulty options (such as having easier enemies to kill, activate hunger…) 

  • Block physics

It is still at an experimental level so it is not activated by default. However, you can test it by activating it in the game creation window.

All that is only a part of the main new features of this version. You can find all the latest novelties in details in the updated release note here

Note for all AZERTY players: you have to reconfigure your keyboard. You will find a new button, at the top right-hand corner of the option window to setup all the shortcuts into AZERTY. 

As usual, do not hesitate to tell us what you think on our forum or on social networks. We gladly read all of your remarks. 

But above all: have fun!

We are glad to present the early access update! Here are the main new features you will find:


Our second planet, Istara, has been highly improved, graphically and technically. Istara is a cold forest planet with three biomes in it: the swamps, the sequoïa forest and snowy forest. A new population of animals appeared : spiders, brakhs (a local boar) and bees. New trees were also added: pines, spruces and above all, the giants sequoïas.

New vehicle : the Spacejet

3 new control blocks have been added: the Gyrograv block, the Spacejet cockpit and a directionnal thruster. You can now get into space by building a spacejet with those new elements! 

The thrusters allow you to control the direction of your ship. You will need 6 thrusters, one for each direction to fully control your ship (Forward, backward, move laterally to the left, or to the right, up and down). If you put only 2 blocks forward and backward for instance, you will just be able to go forward or backward.

Do not forget to check the key bindings options: we added a vehicle section so you can set your bindings according to your preferences, with no effect to the character bindings (on foot). 

Workshop on Steam feature : Share your plans with the community!

You want to show to the community your brand new spaceship you just made? You want to try a house a friend of yours did? 

By pressing the “P” key while in game, you will open the plan sharing tool. This tool allow you to share every plans you created with all your local saves, but also with the rest of the world directly on Steam Workshop. Just drag and drop a plan from this new screen to your inventory and put it in your world (if you have the right blocks to build it!) Just drag and drop a plan from your inventory to the workshop, add it and bam! It’s online! 

New community feature: Transforming a creative universe into a custom universe

Build your world in creative mode, then transform it into a custom universe (“C” button on the universe’s list). The custom mode is your universe with no scenario. You will start with an empty inventory and a knowledge of every recipes. More options to customise this mode will be added in the future.

New features for the creative mode

You can now put creatures to create your own swarming dungeon! Eww... ! 

You can now define the spawn point for the players by using the /setspawn command. Use it for example to set the spawn point in front of your dungeon. 

You can also enable or disable the inertia using the command /togglemomentum. Our artist team asked for this option, and some of you will definitely like it too! 

Recorder improvement, and plan setting enhancement 

Right click now registers automatically an object. The algorithm now spreads to all the blocks linked to the one you are targeting. You’d better separate your object from the ground before you do that ;) 

New death system

Death is always hard to balance and above all, today we don’t have every tool to do it. From now on, when you die, you will loose all your inventory but your weapons, ammo and armor. You will need to come back where you died and click on the bag to loot your inventory. 

Make some backup chests before you go kill some monsters, who knows ;) 

New quest log

You can now follow a secondary quest by selecting it from the journal (press “J” key) and by clicking on the “Follow” button on the top right corner. 

3 characters will wave at you at a moment during the adventure (at the end). Keep an eye open ;) 

You can also check every modifications and improvements we have done in the last seven weeks on the detailed release note of this new update here

Note for all the AZERTY players: You need to reset your key bindings manually in the game options, due to the new spacejets mechanics, we currently can’t mix US and FR key settings anymore. We will provide a fix in a future patch regarding this issue.  

Note for the builders: you can now access the old “EA1” version to create all the blueprints you want, and then copy them to the new version folder. To access the old version: right-click on Stellar Overload in your game list, choose “properties”, and go to the “betas” tab. Select the “steam_ea1_v0.8.5.2” version in the dropdown list. 

As usual, we have open a new section on the forum. Do not hesitate to tell us your feelings about this new version of the game. 

 And most importantly : Have fun
