Frequently Asked Questions

What version of Sins of a Solar Empire is supported?
Sins of the Fallen is a modification for Diplomacy and will be ported to Rebellion. (Currently Diplomacy 1.34).

How do you install and activate Sins of the Fallen?
Please read How to install and activate Sins of the Fallen.

Why does your mod have so many folders?
As Sins of a Solar Empire is a 32bit game it is restricted to 2GB of ram utilization as well as other various hard coded limitations. The stacking structure used with this mod allows more than 2GB of content by allowing portions of the mod to be loaded. 

Will you support Entrenchment or Vanilla?
No, I did have previous versions that supported Entrenchment (See Release History), but have decided the it was too much effort for one person to try and maintain both.

I hear you have a BSG mod too, why isn't it posted here?
For various reasons moddb is no longer hosting any BSG mods, therefore the downloads hosted on this site will never contain any BSG related content.

Sins of the Fallen

A quick update on the mod, 2013 and what's in store for 2014. 

 It's all about customization

Sins of the Fallen is a fully customizable mod for Sins of a Solar Empire. In fact it pioneered the concept of splitting factions into multiple mini-mods creating a truly flexible approach to creating unique gameplay experiences. Want a total conversion feel with Fall of Kobol or Transhumanity- no problem, just activate those factions.

Sins of the Fallen is one of the largest mods for Sins of a Solar empire boasting 6 unique expansion factions added to the already existing 3 vanilla factions . This works out to 16 choices when selecting your faction and loyalist/rebel decision.

2013 saw new Titans, corvettes and abilities added for Rogue Loyalist/Rebels, Hypercorp Loyalist/Rebels, Plague, and FoK factions. Each faction also got a host of new Research subjects supporting the new Rebellion features.

It's not just about the factions

Multilingual Support
Sins of the Fallen supports 3 additional language translations for string text: French, German and Spanish. Yeah they're Bing translated but guess what... That's what Stardock does too!

Planets, Planets and more Planets
Sins of the Fallen boasts the largest number of high quality planets in any sins mod. Choose from 5 different optional systems adding new planets, gas giants and moons to any map in the galaxy.

New for 2013 is the Kobol system which initially has 10 new planets but will grow larger in 2014.

Optional addons help increase the fun by adding things like capturable moon bases or alien artifacts to find, adding optional effects and giving starting flagships to each faction.

New for 2013 are the addons for disabling Titans and Superweapons, Adding Bonus Density to maps and Effects.

Don't like TEC as the militia every time? Solved- just activate an optional militia for your desired faction (requires the corresponding faction to be loaded). This works great for setting up a total conversion with FoK.

Arggghh! Pirates!
One of the new additions this year is Light (default) and Heavy Pirates. Heavy pirates include capital ships with their Raids (Thanks to SZO) while light pirate raids will work like usual.

Another new addition to Pirates is the ability to set Rogue as the Light or Heavy Pirate variant.

What's in store for 2014

First and foremost is to finish Nephilim . I've already acquired new assets that will be awesome for the faction and will be designing their abilities for a release sometime next year. 

 More Artifacts
I don't want to spoil the surprise- so lets just say more artifacts with more interesting gameplay implications!

 Random Events
More random events unique to Sins of the Fallen!

 New NPC
A new NPC that will replace the pirate AI with a completely new look/feel and capabilities (including research available to the pirate class NPC). Thew new NPC assets will also be available to replace as the Militia type.

 Bug fixes and enhancements
There never seems to be an end to finding missed issues (thanks to many of you) or improvements I want to make ;)

Thanks to everyone for their support and feedback over the many years. It's been a lot of fun making this mod with you.

This mod isn't dead is it?! It's a relief to see something other than the 9001 Star Wars/Star Trek Mods. Not to insult the afforementioned in anyway...

I highly doubt Star Wars factions are going to be added into this mod, there are too many Star Wars mods as it is, i know of 4 off the top of my head, the next update will probably be the completed Nephilim and with any hopes the new Pirate NPC.

I reinstalled all the datas,i deactivate and activated them again (of course i restarded) and still an error comes up and the game closes... normal without the mods i can play but its sooo boring after SOTF .... so please can someone help me?

Hey there, got a question. I downloaded the Fall of Kobol mod on its own, managed to install it and get it working after half an hour last night, but today if I try and open Rebellion I'm getting a message up saying something about 'it came from above', which I presume is to do with Sins of the Fallen, and then says I need to restart the game after initially activating the mod. The problem here is that every time I reopen it, I'm just getting the same message.

Are you talking about the Loading Screen, because you will always see that message on start up, and it's a passage of some form about the Plague, one of the races for SotF.
