ISBS - Living Systems

In 1 collection by Ankain
Improved Space Battles
5 items
Improved Space Battles Standalone - Living Systems adds life to your interstellar empire by populating it with hundreds of autonomous civilian vessels. Your systems will no longer feel empty and devoid of life as civilian vessels buzz around from planet to planet on their daily business.

This mod is compatible with Stellaris 1.6 and 1.7. Let me know if you run into any issues.

Civilian activity will grow along with your planets and economy. After your empire reaches a certain size, civilians will start to leave the system in search of new opportunities. Watch as your empire grows from a single starport to a living, thriving galactic hub!

It is HIGHLY RECOMMENDED that you use this mod in conjunction with Improved Space Battles [Graphics] to experience the mod as intended. This will greatly reduce the visual clutter caused by civilians.

To safely remove the mod, set civilian density to OFF and wait 1 year before disabling it.

Interstellar Civilian Fleet

Billboard Advertisement Ship

Civilian Vessels
  • Adds civilians to Stellaris. Civilians represent the general population of your empire and will automatically move around within your borders.
  • Adds over 40 different civilian ships, spawned at random to ensure each solar system looks different. Also includes Billboard advertisements within systems and interstellar fleets that will move around within your empire.
  • Highly customisable settings (through in-game policies) to ensure you can play with minimal performance impact. Read the policy tooltips!
  • It will take several years to populate your systems after enabling this mod.
General Description

Civilians fleets are created from planets with spaceports. Once a planet grows to 4 pops or more, civilians will start leaving the planet to explore the solar system. Civilian activity increases along with the planet population - larger planets will generate much more activity within a system.

As the planet develops, different ships such as billboard advertisements will begin to appear . When your empire grows beyond a certain size, civilians will also start leaving their original solar system and move around in your empire.


The biggest concern I have with this mod is performance. To ensure that it is able to run on a wide variety of systems, I have added several customisation options. These options are controlled through empire policies (though you have to use "free_policies" through the console to change the same option multiple times). The following options are available:

  • Civilian Density [Normal (default), Low, Off] : Controls the number of civilian ships spawned in player empires. Lower this to improve performance. Turning off civilian density will also disable the mod, allowing you to safely remove it after about a year of in-game time.
  • Intra-System Billboards [Enabled (default), Disabled]: Controls the spawning of billboard advertisement ships in-game. I was unsure if people might find the ads distracting so I added an option to turn it off.
  • Interstellar Ships [Enabled (default), Disabled]: Controls the spawning of Interstellar Civilian Fleets that move between systems.
  • AI - Living Systems [Off (default), Contact only, All]: Controls the spawning of civilians in AI empires. Contact only means civilians will only spawn in Empires you have contact with. All means civilians will spawn in all AI empires (pretty big performance hit late game).

    Feedback, suggestions or criticisms greatly appreciated!

HUGE thanks to draft3dd for the Russian Localisation!

For an improved Stellaris experience, use this mod along with the following ISB mods, which adds 5 new super-capital class ships, over 50 new technologies and 11 doomsday weapons - including planet destroying, star system destroying and anti-fleet super-weapons.

@Hydra99 The private sector funding cutting edge research even in the future!

LOL I attacked a civilian and got research out of the Debris

@catonaj @Shits'N'Giggles Unfortunately no, I've been trying to figure out a way to do it for a very long time.

@Teldara Hmm the main issue with that would be wormholes, and needing to duplicate every civilian ship design with the 3 FTL techs.

@6480 @Dawn's Tear Thank you! I'm really hoping that we get the ability to mod away the fleet icons a later update/expansion.
I love the mod but is there any way to disable the faction flag that they have? the all the civilian ships makes it a tad cluttered.

This mod is so awesome, I love the billboard ads. Let me know if you need someone to make graphics for more. Good luck trying to figure out how to hide the civilian ship icons.
Teldara Jul 10 @ 6:53pm 
Is it possible to have the ships to use the FTL travel based on the set rules? It's a little jarring when you see a civilian ship use warp drive when using Hyper Lane only

After getting to late game status This should have been in the game from the get go! my map filled with my empires civilians and others and it was alive. Bill boards every where. Glorius as robbaz king of all humans would say. Hope you make more bill boards or even star wars empire themed ones hehehehe. :D thanks again for this definetly was needed.

one thing that I noticed that probably would be good to change is that the civilian fleets should not park inside or very close to military fleets. They should avoid them.

I actally really like this mod - however I would like to see the ability to turn off the fleet icons for the civilian ships - its distracting and unecessary to see them
