5X - The Ultimate Balance Mod v4.2.1 (Next Update Aug 25)

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 Steam or on Nexus Mods[]. If you are going to use UCP with 5X, it is necessary to use the 5X UCP Compatibility mod

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 4.2 Changes:
  • Military outposts are now stronger (as strong as a star base) and now have to be researched in the tech tree (tier 2). Advanced military outposts have also been improved to be as strong as titans. They are now given for free when you research that node rather than occuring as a choice.
  • Re-arranged a lot of early game techs based on feedback on the changes I made previously, particularly on the bottom part of the tech tree. See government, physics, and biology in particular. The pollution techs were moved around, and missile base is now back in advanced fusion, among other things.
  • Pollution processor no longer upgrades atmospheric renewer since atmo. renewer is no longer given for free. Now there's just one version of the pollution processor that gives 15 on any mineral richness.
  • The Orion guardian is now stronger. Let me know if I overdid it. The intent is to be able to beat the guardian once you get past the Zortrium armor level.
  • Changed the icons for several added 5X techs, mostly in the transdimensional node so they aren't using the same icons as other techs.

Version 4.2.1 Changes:
  • Nerfed pirates a bit. Destroyers and cruisers will be sent out later. Pirates stop spawning at turn 200 instead of 150. This is due to complaints that pirates are too hard on pre-warp.
  • Adjusted Orion guardian blueprint again to make it more effective against fleets of smaller ships (more auto fire weapons)
  • Updated race perks for UCP compatibility mod to reflect the recent UCP change to high gravity

Past changes can be viewed in the change log.

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!

Also check out these related mods:
  • Split Tech Tree is an addon for 5X that re-arranges the entire tech tree into 8 separate branches to make it more like a MoO2 style tech tree. This completely changes the tech tree strategy, so if you want to shake things up with a totally rearranged tech tree, give it a shot!
  • 5X Lite is a lighter version of the 5X mod that includes most of the balance adjustments of 5X but none of the added technologies, tech tree changes, added uber biomes, etc. It's for players who want a more balanced game but one that's closer to the original in terms of its scope.
  • ALL AI + 5X galaxies allows you to play with every race at the same time on 5X galaxies and allows you to use 5X galaxy ages/density settings with potentially every race on an extreme circle galaxy. This mod can be used standalone or with 5X. There is also a no wormhole variant.
  • 5X UCP Compatibility Mod is for players using 5X with WhatIsSol's Unofficial Code Patch. It re-enables the bugged technologies disabled in 3.4 because those bugs are fixed in UCP, and it takes advantage of some modding features added by UCP. I highly recommend using both UCP and this addon!
  • Custom 5X Assets contains new ship icons for the alternate hull types introduced in v4.0 as well as new planet icons for the added uber biomes.

And did you add all those galaxy types???

Wow, there so much more. One question as you have 2 different kinds of hulls for each class, what happens with creative races?

The lithovore perk has fixed population grown tied to mineral richness. They grow slower in general because of that
jpoisel Jul 10 @ 3:47pm 
Hey, Spud, is it Silicoid that's nerfed in pop. growth, or the Lithovore perk itself?

Just uploaded a minor update to address a few issues. It shouldn't break any save files.

@Venusaisha he wrote OUTDATED afterwards...he realised is not working...and Yes...the loading was after all those 5x and the battle pods i had too...but i tried it without any other mods but the growth and it still didn't yeay...outdated
Venusaisha Jul 9 @ 12:46pm 
5x has its own thing, however if a mod is "OUTDATED" then not up to current patch. It pays to be updated, also did u load it after 5x mod, ucp, 5x galaxy and 5x compatibility? :Diplomat:

I have a mod called PopulationGrowthSpeeds.yaml ...but is not there any file that deals with population growth within this 5x mod, ucp, 5x galaxy and 5x compatibility? doesn't break my game or just the population growth mod is not working...

I got it to work as it should... I started from scratch, which I found out I did not have/need to, and slowly activated/added the other mods but kept 5x at the bottom. I had it towards the middle, with other cosmetic mods, 5x assets, uber planets, realistic, and things as such right after.
Thanks again for this great mod. Wish the dev/pubs would pay you to actually fix this mess lol

Also, the ironclad is not build-able like it used to be either :( ] [/url] ] [/url]

I will attempt to remove all previous mods and see if something changed it
