StellarStellaris


We have uploaded the previous version of NSC to the workshop for those who wish to continue their save games before upgrading to this new version. Please note that this is only updated when a major update is released for NSC (that requires a new save game).

May 6, 2025 - Season 1 - Update 15 (Mod Version 1.0.15)
This is a minor update that should work fine on existing games.


  • Return of the Jed... erm, Strike Cruiser - As an apology gift for messing up the 4.0 update, and in appreciation for everyone being patient and supportive while we fixed our mistakes, when you start up your game and reach the proper tech level, you will notice that the Strike Cruiser has returned as its own separate ship class. In addition, it has a new weapon that fits into the PD slot - the Hyperdrive Scrambler, which can target ships directly and shut down their FTL drives! At this time, the Strike Cruiser just has the sections that were used for the Cruiser upgrade, but we'll be adding more and doing more with the Strike Cruiser in Season 2!

  • Fixed all bugs causing problems with NSC ships not working in 4.0 (HOPEFULLY!!)

  • Fixed numerous other bugs and errors discovered during testing.





May 5, 2025 - Season 1 - Update 14 (Mod Version 1.0.14)
This is a minor update that should work fine on existing games.


  • Added a new tech file to overwrite the individual techs for Battleship and Titan, to make sure that Battlecruiser and Dreadnought techs pop up in the appropriate order. With this change, NSC now no longer overwrites the vanilla Engineering tech file, which should drastically increase compatibility with other mods that make changes to vanilla engineering techs.

  • Fixed a bug where the Explorer and Cruiser did not have proper access to their cloaking devices. Explorers will now use the same cloaks as vanilla Science ships.

  • Fixed a coding bug with the Diagnostician job given by the Galactic Hospital.

  • Fixed several minor coding bugs with NSC starbase buildings & modules.

  • Changed the Diagnostician job to remove bonuses that no longer exist in 4.0 and added new bonuses.

  • Removed several NSC loading screens to save file space (some are still present for troubleshooting purposes as well as because I like them.)

  • Fixed a bug where localization files other than English did not update properly for 4.0.





May 5, 2025 - Season 1 - Update 13 (Mod Version 1.0.13)
New Save Game is Absolutely Required For Stellaris 4.0


Updates & Bug Fixes

  • Mod updated for Stellaris 4.0.

  • Fixed the Diagnostician job not working properly for Gestalt empires.

  • Fixed a bug that allowed the Flagship to be built by Federations.

  • Fixed a bug where Explorers could not be built at Beastports.

  • Fixed a missing section name for the Level 3 Explorer.

  • Fixed missing names and descriptions for the 4th and 5th levels of the Galactic General Hospital megastructure.

  • Fixed a bug that was causing the Planetary Construction Office to not work properly.

  • Made a few code changes in an attempt to fix some of the "broken" ship behaviors given by the NSC Combat Computers. (We won't know if this actually works until the community can test it out.)


New Features & Feature Changes

  • The NSC Mod Menu has been removed for the time being, and will be redesigned in the future with more stable and bug-free coding.

  • The Machine Shipset has been removed since the original creator of it recently updated the original mod here: mod_detail.php?publishedfileid=2077186491

  • Ships no longer have access to ALL combat computers/behaviors - ships now have access only to the behaviors that make sense for that class. (This should help in combat computers running off the screen when using multiple mods that add computers.)

  • The Mothball Fleet feature has been disabled pending a rewrite of its coding necessary to make it less buggy and more useful.

  • Added cloaking devices for the Explorer class.

  • The Strike Cruiser Interdiction module has been moved to the Aux slot and now has a limit of 1 per ship.

  • The Strike Cruiser now has access to a targeted FTL Disruptor weapon, and can equip 2 per ship.

  • The Privateer Operation doctrine now reduces logistic upkeep of ships and increases trade output of jobs (Its former functions are no longer relevant after 4.0. This doctrine will be renamed something more appropriate in the future.)

  • Renamed the Federal Reserve Bank starbase building to Central Reserve Bank, since not all governments in Stellaris are federalized.

  • Changed the build limit on Level 1 Explorers from 3 to 4. Limit is still capped at 10 after Level 2 is researched.
