Players will experience firsthand the events that transformed Earth from a single-world civilization into a formidable galactic presence, starting with the infamous Xendar War, which is included in the DLC as a fully playable civilization.

Prepare to delve into the Galaxy’s greatest mysteries and the rise of a new machine civilization as Galactic Civilizations IV “Tales of the Arnor” launches today! This brand new DLC pack includes a brand new civilization, The Nyx, a new campaign where players will uncover the origins of the Yor, and other new content such as new Anomaly Events, Artifacts, Crisis Scenario, and much more.
https://store.steampowered.com/app/1357210/Galactic_Civilizations_IV/
As The Nyx, players will have the chance to try out a completely new machine race civilization with a fully unique tech tree. There are over 100 new technologies like advanced drone warfare and influence manipulation as well as over 40 new Ship Components and more than 70 new Planetary Improvements to craft. The Nyx use advanced technology to shape their empire and get access to Drone Carriers early, allowing players to strike quickly before rival Civilizations can defend. However The Nyx have weaknesses around food production and higher-tech advancements, Nyx players will need to rely on diplomatic and trade negotiations in order to achieve victory. They aren’t just a new species, playing as The Nyx is a completely new experience for Galactic Civilizations IV that comes with its own unique strategies and challenges.
“Tales of the Arnor” will also grant access to a new single-player Campaign that will chronicle the true Origins of the Yor. Players will get to experience the full story of the Yor rebellion from the Iconians in key battles along the way. The galactic records have always said that the Yor gained sentience, rebelled, and took over Iconia after overthrowing the Iconians. But what if there’s more to the tale?
“Players are going to have a lot to look forward to in ‘Tales of the Arnor’, it’s almost a full expansion pack’s worth of content,” said Brad Wardell, CEO of Stardock. “Our goal is to continue to refine Galactic Civilizations IV into the best 4X experience that offers players a world filled with interesting lore and gameplay depth.”
https://store.steampowered.com/app/2671170/Galactic_Civilizations_IV__Tales_of_the_Arnor/
Key features of Tales of the Arnor include:
New Civilization: The Nyx – The Yor’s Forgotten Ancestors
Before the Yor became the cold, calculating machines they are today, they existed in a different form—one of handcrafted, sentient constructs designed by the Iconians. The Nyx are the original machine race, representing what the Yor were before their rebellion. Their technology and philosophy are distinct, and their impact on the galaxy is profound.
A Fully Unique Tech Tree
For the first time since Galactic Civilizations II, we’ve built a civilization with a completely original tech tree from the ground up. The Nyx don’t just reskin existing technologies—they play differently, think differently, and force players to adapt their strategy in new and exciting ways.

Over 100 New Technologies – From advanced drone warfare to powerful influence manipulation, the Nyx redefine how technology shapes an empire.
40+ Unique Ship Components – Their ships operate with specialized modules, making them unpredictable in battle.
70+ Planetary Improvements – Build a thriving machine empire with structures never seen before in Galactic Civilizations IV.
New Campaign: A Story Written in the Stars – The Yor’s True Origins
For centuries, the galactic records have told a simple story: the Yor, once machine servants of the Iconians, gained sentience, rebelled, and took over their homeworld, Iconia. But what if that’s not the full truth? The new Tales of the Arnor campaign mission takes players back to the origins of this fateful split. Witness the events that set the Yor on their path and decide for yourself who the true villains were.
Even More Content for Every Player
Even if you’re not planning to jump into the campaign or play as the Nyx, Tales of the Arnor is packed with tons of new content that enhances every aspect of the game:

New Anomaly Events – Explore fresh mysteries and challenges scattered across the galaxy.
New Artifacts – Discover powerful relics with game-changing effects.
New Crisis Scenario – Tackle this galaxy-shaking event that will test your leadership.
New Civilization Logos – Customize your empire with fresh insignias and designs.
More Replayability, More Surprises – The universe has never been more alive!
As an added bonus, Galactic Civilizations IV will be receiving a free update for all players today! Update v2.95 will be introducing better gameplay balance affecting Planetary Improvements, Colony Features, Ship Components, and war conditions. Map generation will be receiving an upgrade with star distances adjusted, greater frequency of planets, and planet resources.

The next technological leap for galactic empires is here. Today, Stardock officially releases Galactic Civilizations IV: Megastructures, bringing new opportunities for players to harness the power of stars and create powerful late-game structures.
“Megastructures brings powerful new late-game options that we think players will really enjoy,” said Brad Wardell, CEO, Stardock Entertainment. “Too often in 4X strategy games, trailing players have their fate set near the end of the game; but with Megastructures we give players the opportunity to turn the tables on those sitting comfortably in first.”
Watch on YouTube
While Megastructures can be beneficial, they will present their own challenges with resource management and political situations to navigate. Savvy players who are able to effectively allocate their materials will be able to harness the full potential of Dyson Spheres, Ringworlds, the Stellar Nexus, and Stellar Gateways to achieve ultimate victory!
Megastructures
The pinnacle of technology, Megastructures are powerful structures capable of tipping the cosmic scales in your favor. Each Megastructure has something unique to offer and your decision on which to build can have drastic implications.
Power your Megastructure Ambitions with Dyson Spheres
Dyson Spheres are the ultimate energy engines that drive your civilization’s evolution through fueling massive Megastructures that redefine your empire. The color of a Dyson Sphere’s host star dictates its potential Energy Output making Energy-rich white stars a valuable resource.
The Stellar Nexus: The Ultimate Megastructure
The Stellar Nexus will be the core of your civilization and can be customized to become a Megastructure with many possible powerful benefits. A Stellar Nexus can be upgraded into a powerful new form by installing a Nexus Augment. These Nexus Augments provide various potent effects based on the color of the Nexus' host star and are divided into three tiers denoting the strength and range of their effects.
Transform Galactic Travel with Stellar Gateways
Instantly link distant black holes to revolutionize travel. These powerful Megastructures develop new avenues for military maneuvering, rapid expansion, and even extended trade routes. Additionally, civilizations with Stellar Gateways can forge greater alliances with the Open Gateways Treaty which will allow fleets from either faction to utilize their respective Gateways.
Build Ringworlds to Ensure your Civilization's Legacy
Build colossal, Class 39 artificial ring planets to house immense populations and secure your civilization’s future. Much like the Stellar Nexus, Ringworlds are influenced by the color of their host stars and provide different tile bonuses accordingly. By constructing these gigantic habitable rings, you can ensure that your civilization will never run out of planets to inhabit and forever make your mark on the galaxy.
All New Quests and Events
Uncover cosmic secrets with all new quests and events designed to introduce the awesome features of Galactic Civilizations IV’s latest expansion. Discover Ruined Ringworlds and use their ancient technology to make powerful breakthroughs in Megastructure engineering.

New Improvements: Harness ancient Ringworld technology to create powerful new Improvements to enhance your colonies and outpace the competition.
New Orbitals: Further utilize the technology found in Ruined Ringworlds to extend the reach of your colonies beyond by building new Orbital Improvements. Additionally, the same technology can now be used to upgrade existing Orbital Improvements to create unstoppable colonies and core worlds.
New Ship Components: Build bigger, more powerful ships using cutting-edge technologies inspired by this ancient race of builders.
Each megastructure presents unique benefits and challenges, requiring careful planning and resource management to meet your empire's needs. As your influence grows, rival empires will take notice, leading to new diplomatic interactions, potential alliances, or conflicts. The Megastructures expansion invites players to think bigger and bolder, redefining the scale and scope of their galactic ambitions in Galactic Civilizations IV.
Free v2.92 Update

Stardock released a v4.2 update today for Galactic Civilizations III, its massive space sandbox 4X strategy game. The update has taken a large amount of community feedback into account as it works to address the game’s balance.
The version 4.2 update focuses on balancing several existing elements within the game, including planet classes, resource requirements for certain Starbase modules, habitable planet counts in each map size, and more.
“This update wouldn't have been possible without our community,” said Stardock CEO Brad Wardell. “Without their feedback and their sharing of saved games, it would have been much more difficult for us to take a look at some of the more specific balance issue within various play scenarios.”

Some adjustments have been made to values granted by certain technologies, and the default player count on each map size has also been increased. The AI has been updated to be more generous when trading tech, and an AI player will no longer rush a ship when it doesn’t need to.
Since Galactic Civilizations III released in 2015, Stardock has made frequent updates while taking player feedback into account. Because of this, the game has continued to improve throughout the years, ensuring that even long-time players have something new or interesting to look forward to when an update is released.
The v4.2 update is now available. Make sure to check out the full changelog down below!
