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.

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.

Who exactly allied with the warlords in this game? Other warlords? From my perspective i kinda feel like they'd be on their own because most of the time the (generic) warlords are too busy fighting themselves to be trying to find friends. I know i'm kinda ranting here, but i'm pretty sure that at one point Daala killed the other warlords in the original canon because they couldn't set aside their differences. at least I think that's how it went...

TL;dr Are the warlords making any friends and/or allies?

Depends entirely on the Warlord. In canon Grand Moff Ardus Kaine's Pentastar Alignment basically stopped fighting everyone for a time, and they have a unique tech that improves their diplomatic position because it. Grand Admiral Thrawn made agreements if not alliances with all the Imperial factions during his campaign against the New Republic, and in this mod he's the only Warlord still on good terms with Darth Vader.

Zsinj and Isard on the other hand indeed do not make friends easily. However, since the Warlords are an umbrella faction for all of these guys, you'll find their diplomatic relations are kind of mixed because of it.

I must be an annoyance on this page by now, but i just glanced at the image at the top of the screen and see that its the rebel (New republic?) captured executor class fighting an imperial/warlord executor class. Is this a hint of something that may be in game? or did you just like the photo and use it?

annoyance? never. We always appreciate interested community members. As for the rebels getting a hold of an executor in this mod, it is entirely possible, or I should say, will be entirely possible in the next release, for the Rebel Alliance to capture Kuat and begin to produce SSDs the same way you can now as an imperial player. As for the New Republic, well, for that you'll have to wait and see :-P

I'm afraid this probably won't happen simply because Sins does not handle retexturing ships very efficiently. You actually need to duplicate an entire model just to use a different set of textures. For the Nighthammer this was worth doing since being an all black SSD was its distinctive feature, but just to add emblems or logos is not really worth it. Especially for a ship as large as the SSD.

That said, it would be pretty simple to make a minimod that would make all SSD have the New Republic logo on them, so you could just activate that when you want to play the New Republic on a map with Kuat.

So what do you fine folks think about Valve allowing people to charge for mods through Steam? Also, the preview video you did with Gul Dukat was great; can't wait to see what else you guys have cooking up for the next release that we haven't seen yet!

I happen to think its quite absurd, actually. too many mods are based on content that falls under creative commons licences- take star wars, for example. We are allowed to use the images, sounds, etc, as long as we're not making money off our product. the instant we start to, Disney and their rather large team of lawyers sends us a nice cease and desist letter.

I'm glad they're testing it with Skyrim first. :p Sins will never have Steam Workshop so it is probably nothing that will concern this corner of the galaxy.

And thanks! There will be more to come.

I have to say, I enjoyed the video that you did with Gul Dukat ('Gul Gaming') on YouTube, GoaFan77. Any taster of the next Interregnum update is always a plus for me.

The Imperial Capital ships that have had new models implemented look quite nice, indeed! Looking forward to more videos between you and Gul. ^^
