5X - The Ultimate Balance Mod v3.3

Spud Dastardly presents the biggest Master of Orion: Conquer the Stars mod in the galaxy! This mod is massive overhaul of the gameplay experience. The list of changes it makes is far too long to list here. It's like a whole new game! It includes a total rebalance of every aspect of gameplay, new technologies, improved AI, and much more.

Languages/Sprachen/Языки/Idiomas: English, German (Deutsch), Russian (русский), Spanish (Spain) (Español (España))

The Unofficial Code Patch by WhatIsSol is highly recommended for use with or without this mod! You can get it on Nexus Mods[]. For best results with 5X, you should delete ShipBlueprintTemplates.yaml from the Unofficial Code Patch folder and load the local mod portion of the patch after 5X.

5X was featured in a series of videos by YouTubers Mal and Sabouts! They played two games on impossible difficulty (using version 2.3.1). You can see the first video above, or click here to watch it on YouTube. At the end of the second game, they did a review of the mod and the game which is featured above, though there's some spoilers on how that game ended up, so you might want to watch the whole series first.

I've put many hours of work into this mod! If you would like to show your appreciation with a donation, you can do so here.[]

Version 3.3 Changes:
  • Fixed dragon not using its fighter bays ever.
  • Added minor rifle improvements to each hyper advanced chemistry node. Previously that node was the weakest of the 5 in terms of usefulness.
  • Reorganized some of the mod file contents. This is a backend change only.
  • Added two new starting ages: Microlite Construction and Multistate insulator. Similar to the lopsided starting age, you get all of the techs up to those respective tech nodes but nothing else beyond the pre-warp techs.
  • Adjusted tiny spiral and small spiral galaxy generation for better star distribution and to fix occassions where the galaxy would not generate as many stars as it should
  • Planets now degrade due to pollution 1 turn after hitting the pollution limit
  • Antarans now send a minimum fleet of 2 frigates (previously 1)
  • Added a partial Czech translation by Frost_DeatH. Hopefully to be eventually completed.
  • Shifted all techs in the tree to the right so Extreminate no longer overlaps with the UI thing on the left (Credit to Frost_DeatH for doing this)
  • Adjusted Antarans a bit. Their titans and doomstars now use quantum missiles to boost their attack power. Now their fleets are allowed to include more destroyers, cruisers, and battleships than were previously allowed. This should allow for more balanced looking fleets rather than 80 titans plus a much smaller number of smaller ships (the quantum missiles should also lower the number of titans you see)
  • Reduced production cost of Volcanic Cooling

For previous version changes, see the change notes.

Version 3.3 is the final major 5X version I have planned. I will still update the mod to fix bugs as necessary or add translations as they become available.

Any feedback is welcome, and I'm happy to answer questions about specific changes. The French localization for 3.0 is not available since my translator quit playing MoO. If you enjoy this update, consider donating (link near the top). I put many hours of work into it!

Yes, you can use the UCP from the Steam workshop. Note though that you still have to go through the install instructions for UCP on that mod page instead of just being able to subscribe and use it.

I uploaded version 3.3 of 5X a few hours ago. I discovered that the horizontal position of Evolving Technologies was erroneously reverted back to its default position, creating a display issue. I have just corrected this with a quick update.

@Spud Dastardly

can i install the Unofficial Code Patch from the Steam Workshop instead of Nexus and then install your 5X mod?

Thanks Reriser, rothsky, and Superman was my bitch :)
@Num7 The Elerians usually do pretty well in my games. I haven't noticed any issues. Has anyone else noticed issues with the Elerians?

Spud, I congratulate you with a small holiday - the anniversary of your modification, which kept the game afloat after the developers dropped the project! I wish you success in studies and a great career and strong family life! And sorry for grammatical errors!

It seems most of the games in which an Elerian AI appears, they get crushed and are always the worst CPU player, lagging behind. Is it possible that their maluses are crippling their growth pretty bad? Let me know if it has ever been brought up.

Thank you! Excelent job with this mod!

This mod is awesome! I've noticed a few minor bugs/anamolies but it really improves the game.

I wish I could, and I've tried before, but it leads to UI problems and stability issues (hence the galaxy not loading properly with that mod). The game is not designed to handle more than 9 players. It's better to leave that for a separate mod I think for those players who want to try to get it to work.
