Star Wars: Interregnum is an upcoming mod for Sins of a Solar Empire: Rebellion that builds off of the highly successful Enhanced 4X Mod. Fleeing the unknown terror that is chasing the Vasari, the factions of Sins of a Solar Empire stumble on a temporary wormhole that takes them to a galaxy far, far away. The sudden arrival of armadas with trillions of refugees and thousands of warships between the events of Episodes 5 & 6 forever alters the Star Wars universe and plunges the galaxy into an unprecedented period of chaos and violence. Begun, a new conflict has.

12 comments by ahobgoblin on Jan 22nd, 2015

Hello all. Seems an introduction is in order, seeing as this is the first time anyone other than our fearless leader has posted to this page. My name is Ahobgoblin, and I've been working for GoaFan77 on this project for just over a year now. Thus far, I've contributed to the soundtrack and worked quite a bit on elements of the HUD, but recently my efforts have been concentrated on introducing a new challenger into the galaxy. The time has come to introduce to you all the next minor faction entering the fray of the Great Interregnum.

The Atzerri Cartel.

[My apologies to all of you who were expecting the faction reveal for the Rebellion, but you'll have to wait just a little longer for that gem.]

As many of you are well aware, the story of the Interregnum takes place in the Star Wars galaxy, with the factions from vanilla Sins introduced as they flee the dark terror pursuing the Vasari. Until now, however, independent forces of the TEC were still found guarding unclaimed worlds, and this represented a bit of an immersion break. It is my pleasure, then, to introduce the group of rogues, pirates, and mercenaries who have risen to defend their homes and bases from Imperials, Rebels, and extragalactic powers alike, and have replaced the standard Sins militia.

Sometime after the beginning of the Interregnum, representatives from various mercenary forces, smuggler groups, and other organizations met on the planet Atzerri to discuss the galactic situation. It was clear to the leaders of these groups that the introduction of new galactic powers severely threatened their operations. Space, and the worlds and outposts within it, would be at a premium; with fourteen or more independent factions all attempting to carve out sections of the galaxy. Accordingly, it was decided at this meeting that the best and only way to combat the major powers would be to pool forces and resources. Thus, the Atzerri Cartel was formed.

The main goal of Atzerri Cartel forces is to attempt to stop major powers from assuming control of their "business" holdings. In this line of work, there are no heroes, no prestige or glory, and very little in the way of resources. Accordingly, the Cartel employs a ragtag assortment of warships, most outdated or retrofitted, some bought or stolen from major factions, to patrol their base systems.

The following ships could be encountered in the employ of the Atzerri Cartel:

Skipray Blastboat (Corvette):

Identical in form and function to its Imperial counterpart, the Siener Fleet Systems Skipray Blastboat is common among mercenaries and pirates due to their incredible reliability and hyperdrive capability.

CR92a Modified Corvette (Light Frigate):


The CR92a Assassin is a cousin of the more recognizable CR90 Corellian Corvette employed by the Rebellion. Originally built by the Empire to ward off pirates and Rebel fighters, many of these Modified Corvettes have been repaired by Cartel forces and deployed to protect cartel worlds.

Marauder Cruiser (Long Range Frigate):

The variant of the Marauder Cruiser employed by the Atzerri Cartel is the stock design, furnished by the Corporate Sector Authority. Equipped with a single long-range turbolaser battery rather than the missile launchers favored by the Rebellion, Marauder Cruisers are a common sight protecting frontier worlds.

DP20 Corellian Gunship (Anti-fighter Frigate):

Available to the Cartel only in small numbers, the Corellian Gunship is identical in almost all respects to those employed by the Rebellion during the Imperial Civil War. However, due to the high cost
of proton warheads, the magazines of Spacer DP20s are limited to firing concussion missiles only. Typically tasked with anti-fighter defense, Corellian Gunships can be found protecting worlds of higher-than-average value.

Nebulon B-2 Frigate (Siege Frigate):


A redesign of the famous Nebulon B Escort Frigate, the Nebulon B-2 features an increased arsenal and heavier armor when compared to its predecessor. Whereas the original Nebulon B was often tasked to serve as a hospital ship, the Cartel has opted to outfit their large supply of obsolete Nebulon B-2s for planetary bombardment operations.

Dreadnaught Heavy Cruiser (Heavy Cruiser):

Anyone familiar with military history can recognize the distinctive Dreadnaught Heavy Cruiser at a glance. Possessing an imposing profile, these ship were first designed for use before the Clone Wars,
and have since become a permanent fixture in fleets of pirates, mercenaries, and militias. Despite their age several continue to see deployment in Imperial border fleets. Atzerri Cartel Dreadnaughts
are roughly equivalent to those employed by Imperials, with the exception of their fighter complement.

Z-95 Headhunter Squadrons (Fighter):


Before Incom became famous for designing the X-Wing, then snubbing the Empire and producing them for the Rebellion, the company produced a fighter that can be found in every Outer Rim spaceport, and most everywhere in between. The Z-95 Headhunter is old, outgunned by modern fighters, lightly shielded, and beloved by their pilots and owners regardless. Cartel forces deploy Z-95 squadrons from the hangars of Dreadnaught Cruisers and orbital stations.

Y-Wing Bomber Squadrons (Bomber):

One of the oldest fighter designs employed by the Rebellion during the Galactic Civil War, the BTL Y-Wing Starfighter was designed during the Clone Wars to be a capable fighter-bomber. Years later, it
still fulfills that role, despite being considered slow and ungainly by pilots of faster craft. Unlike the Y-Wings employed by the Rebellion, however, Cartel Y-Wings lack proton torpedoes because of their expense, favoring concussion missiles as a substitute.

Ich kann versuche zu helfen, aber nur auf Englisch - es tut mir leid. Es gibt viele Gründe, warum "minidumps" kommen vor. Könntest du ein bisschen mehr Informationen geben?

Is it only this mod that crashes? Does it crash every time?

Do you have all required files for the mod and those are correctly activated?

Do you have the latest update for Sins? There could be something wrong in the update. Try to verify your game data files: go to your Steam Library and right-click on Sins of a Solar Empire: Rebellion, then select Properties. Click the Local Files tab and then Verify Integrity of Game Cache

I seem to be having a problem where whenever a hostile culture takes over my planet the game just stops functioning. You can hear the sound in the background but it just freezes and will eventually give you the message that Sins of a Solar Empire Rebellion has stopped working. I don't seem to have this problem when my planet is bombed out, just the culture takeover.

That is unfortunate. Do you have the stellar phenomenon DLC? Fairly recently I noticed something that I knew could potentially cause a problem with culture overthrows, but I hadn't seen anyone report it. I've fixed the problem on my end, and you can prevent it from happening in future games if you disable random events, but I'm not sure if there's anything you can do for that save game to stop it. If it always occurs even when loading it from a prior save, you may just have to try and do everything possible to not lose it to culture.

hi, well, i found a new silly problem that's affecting all my steam games, that's rebellion and all my mods, SWEAW & FOC and their mods and Darkest Hour and its mods... the problem is that i'll be playing a mod and the game will all of a sudden minimize to the desktop. It doesn't matter if it's a steam game with a mod or a game with a mod.

I have a geforce 970 video card and i'm running win7 64bit.

I heard there was something weird with the 3D settings where they could cause this, but under managing 3D settings you have "maximum pre-rendered frames" and "vertical sync" that use the 3D application settings.

Any thoughts as to how to stop the games from doing this irritating minimizing thing?

Do i even need Vertical Sync turned on for rebellion, or my other games? I know they aren't 3d games.

Thanks for anyone's assistance in solving this problem.

The only thing I can think of is that you have either another application or a windows system message that is launching/popping up during your gameplay and causing the game to exit fullscreen.

For the record, we are not associated with the SoGE project. Interregnum is GoaFan77's own take on a Star Wars mod for SoaSE. Key differences include gameplay style, timeframe, scale, and the fact that Interregnum is not a total conversion.

That said, by all means, download and enjoy!
