5X - The Ultimate Balance Mod v4.4.0

Spud Dastardly presents the biggest Master of Orion: Conquer the Stars mod in the galaxy! This mod is massive overhaul of the gameplay experience. It's like a whole new game! It includes a total rebalance of every aspect of gameplay, new technologies, improved AI, and much more. For a more specific overview of what this mod does, see the Readme on Nexus Mods[].

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 4.4 Changes:
  • Bug fixes
  • Changed population growth speeds and research speed settings. Details can be found in the change notes. If you used Fast population growth speed before, give Normal a try now (basically Normal + microbiotics = what fast previously was, and the other speeds are +/- 25% or 50% from there).
  • Modified the game speed presets (colossal, lightning, etc) and added some new ones. The upshot of using these instead of custom settings it that they also affect how often you get leader offers, which is not available as a separate setting. The "small" speeds give you fewer leaders and the "large" speeds give you more.
  • Hyper advanced colony ships now place a global DNA scanner
  • Defense blueprints will now have some front facing weapons. This means they can fit more weapons on the blueprint, making them stronger, but they now have a weakness to attacks from behind.
  • Removed phasors from Dragon blueprint and gave it more missiles instead. Also adjusted weapon modifications for monsters. No more space creatures somehow shooting MIRV missiles.

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:
  • 5X UCP Compatibility Mod (5XCPC) is for players using 5X with WhatIsSol's Unofficial Code Patch. It re-enables several features which were disabled due to bugs, and it takes advantage of some modding features added by UCP. I highly recommend using both UCP and this addon!
  • 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. Don't use this one at the same time as 5X.
  • ALL AI + 5X galaxies allows you to play with every race at the same time on 5X galaxies (this may cause some issues, which is why it's not in the base 5X). This mod can be used standalone or with 5X. There is also a no wormhole variant.
  • Diverse Specials and Massive Planets is a popular mod created by Morpheus to add dozens of new planetary resources to the galaxy. This version is fully compatible with 5X, but you should load it before the 5X UCP Compatibility mod, and you can't use it at the same time as Split Tech Tree.
  • 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.
  • 5X/Resource Pack Patch mods 5X to use the assets in the Resource Pack mod.
For reference, the correct load order for the above mods if you should choose to use any of them is:
  • 5X
  • UCP
  • DSMP*
  • 5XCPC
  • Split Tech Tree*
  • ALL AI + 5X Galaxies
  • Custom 5X Assets
  • 5X/Resource Pack Patch
*DSMP and STT shouldn't be used at the same time.

@Old1: The game has no check for infiltrated empire spies. It only checks for the embassy pact. To add that would be a code patch. The conditional clause stating about “spy mission” could be removed by 5X.

Maybe it needs to refresh to fix the loop hole. UCP correct version , uninstall game reinstall ,verify cache after u delete it. Then make sure mods are in order in mod section before starting new game.:Diplomat:

I mean that is something 5X most likely can not fix
Old1 May 8 @ 10:38pm 
It should but it doesn't.
Sensei  [author] May 8 @ 2:20pm 
I think that one needs to be fixed by UCP
Old1 May 8 @ 1:25pm 
I think i may have found a bug.
I just had several spy's conduct missions of infiltration in the other empires to find out how they were doing but once they succeeded i still couldn't find out because the diplomatic screen kept telling me that i need an embassy or a spy mission to do that.

Depends on what the save will show.
I don't know yet...

But since i use 5x and ucp and i have no problems, i still think theres something wrong with things i don't use. Or i just didn't see it yet
Inquisitor Sarkessian May 7 @ 4:11pm 
Yupp. that's the the correct load order based on 5X instructions.
I will start a new game and make a save and upload it.
Will that help?
Sensei  [author] May 6 @ 4:24pm 
At first look it looks like UCP is not the problem. Next idea:
I think custom assets needs to be loaded after compatibility mod. But i didnt find that information actually written down somewhere.
If thats not the problem, i am running out of ideas without a save

55.1.1 2.1.41258W64S (28/04/2017 12:18) **** UCP-S.0.5.8a ****
