Galactic Civilizations IV News

[h2]A year’s worth of feedback, suggestions and general improvements make their way into Stardock’s massive update[/h2][h3]Join us today from 1pm - 3pm EST for a livestream event here on Steam[/h3][h3]Full Changelog Here

[/h3][previewyoutube][/previewyoutube][p]
Stardock Entertainment has released the v3.0 Hyperlane Update of its space strategy title, Galactic Civilizations IV. The update introduces major new features such as Hyperlanes, Fleet Supply, a new Map Generation System, updated AI and hundreds of changes based on player feedback over the past year.

“We’ve been pouring through fan feedback for over a year on how to make GalCiv even better,” said Brad Wardell, CEO of Stardock Entertainment. “We’ve tried to address everything, and then some, of what players wanted like more strategic options, more interesting map generation options, better AI, better late game performance, user interface improvements and a lot more.”

Some of the major updates include:
Hyperlanes. While Galactic Civilizations has free-form map movement of units, Hyperlanes provide direct lines between distant stars allowing for very fast travel between disconnected sections of a sector.

New Map Generation. The map generation system of the game has been remade and now includes new options when setting up a game.

Fleet supply.  To allow for more strategic options during war time, civilizations have a Fleet Supply cap that is increased by technologies and planet improvements to make different starship designs more distinct.

Adaptive AI. At higher difficulty levels, AI can adapt their difficulty if they are losing to ensure a more challenging game.  Moreover, at all difficulty levels, the AI has been significantly improved.

Major UI improvements.  Dozens of updates, big and small have been made to the user interface of the game to streamline player interaction.

Performance overhaul. Maps have been made bigger and more stars in a map are supported to go along with a year-long effort to optimize the game engine’s performance.  This should be particularly noticeable on lower end hardware.

Balance wishlists implemented.  Stardock painstakingly reviewed posts on its forums, Steam, Reddit, third-party forums, etc. on balance suggestions, wishlists, etc. and implemented them after careful review.

Visual Updates. The engine received a major update to intelligently anti-alias ship components with each other on a ship to make starships visually look better on screen.

Better Steam Workshop integration. Players can design and share their ships online. Version 3.0 is more responsive, requires fewer steps and generates higher quality screenshots for modders.

DLC updates. All of the released expansions and DLC for Galactic Civilizations have received updates over the past year to provide additional content and features for those who have them.

The award-winninig Galactic Civilizations series is the oldest actively developed space strategy game series starting with its first beta release in 1993 for IBM’s OS/2 operating system.

[h2]Background[/h2]
The Terran Alliance was formed shortly after the confirmation of intelligent life in the galaxy following a probe from a mysterious alien civilization known as the Arcean Empire. This contact soon resulted in the development of FTL travel which quickly spread throughout this area of the known galaxy which inevitably led to an encounter with the quadrant’s most powerful civilization, the Drengin Empire.

The saga of the various conflicts between the Drengin and the coalition of civilizations put together by the Terran Alliance is told elsewhere. Ultimately, the Drengin Empire was defeated and for a time thought permanently restrained.

However, the Drengin continued their ambitions which ultimately led to them discovery the Navigators, a species from well outside the known area of space. These creatures had discovered a series of constructs built, we presume, by the Precursors that crisscross the entire Milky Way galaxy. These constructs, called Subspace streams, opened vast areas of the galaxy to the attention of the Drengin who quickly explored and settled in new areas covertly.

Now, a decade later, the Drengin have regained much of their former might and the Terran Alliance is now frequently engaged in far flung skirmishes with the Drengin in sectors far from home. This After Action Report covers one such skirmish in the Atheris Sector.


[h2]Beginnings[/h2]
Commander Voss has operational authority for the entire sector. Her command post is on planet Aetheris Prime, a promising Terrestrial world.


Voss also has a small contingent of Navigator advisors who have provided some additional technology. They also have agreed to build boreholes on the world that their teams will make use of.


The sector has two clumps of stars in them:


Subspace sensors have indicated that there is definitely another hyperspace using entity somewhere in this sector. But we do not know where yet.


[h2]Exploration[/h2]
The TAS Excursion has found an abandoned Precursor world which we have called Tabit III.


The hyperstorms on the planet make it fairly unpleasant to live but it has a Durantium deposit that may prove invaluable. Nevertheless, not exactly a vacation destination.


A starbase is hastily sent out to Tabit III to help begin processing the ore. It quickly becomes known as “Tom’s Mine” named in honor of Ensign Thomas Yule who, sadly, perished during the setting up of the starbase.


[h2]Operational Report: 90 days[/h2]
Commander Voss’s 90 day report provides many insights on the unusaul sector. It is a very resource rich sector and multiple high quality colonization targets found. No sign of hostile activity yet.


In addition, the Navigators present a new device known as a Hyperlane detector. These are similar to subspace streams except they exist within a sector. It shows that that this sector even has one:


Which spans the gap between the two clumps.

The only negative in the report is that Xia Isoda and her team were forced to relocate to Tabit III since no one would go voluntarily.




[h2]Ringworld[/h2]
This sector also contains a ruined Ringworld.


This could be very interesting later. The ringworld, ironically, was discovered by miners from Tom’s Mine. Naturally, it has been called Tom’s Ringworld.




[h2]Contact: Drengin Outpost[/h2]
After traveling to the other clump of stars, our probe discover the Drengin Empire. They have not, as of yet, noticed us yet. But they are here.


Voss orders the construction of a military starbase to monitor them.

Voss also orders the design of a new Frigate class ship.




[h2]Drengin Travelers[/h2]
The Drengin end up noticing our presence due to one of their Gladiator explorers (i.e. a spy) making their way to Aetheris.


Needless to say, we have no intention of releasing their murderous spy back to them.


[h2]Artifacts[/h2]
The TAS Hobbes has, in its various adventures in this sector, recovered a number of Precursor devices. The most impressive so far is the Gift of the Mithrilar which is a device that when activated on a planet uses some sort of nano devices, operated by a Yor (not the sentient Yor we know today) that increase the intelligence of our citizens. Voss orders it deployed on Aetheris Prime. Hopefully this doesn’t become a decision to regret later.




[h2]Drengin Expansion[/h2]
The Drengin have clearly been operating in this sector for some time. Voss orders additional research into military hardware to deploy in this sector.

Improvements to a game’s user interface go a long way towards improving the experience you’ll get when you’re playing it. The v3.0 Hyperlane update made some significant changes to gameplay, which we’ve covered in the past few developer journals, but today we’ll take a quick look at the new UI features that it adds too.

One of the most essential changes we’ve made to the user interface comes in the form of a much improved Civilization Data Tab. There’s been some major reorganisation to make better use of this essential screen, and we’ve partitioned the whole lower half of the window for a new Civilization Wide Bonuses display interface.


It’s pretty useful to be able to see Civilization Wide Bonuses when you’re making decisions in-game, and having to hunt for it slowed things down. Previously, much of this information was a little difficult to get at: for example, if you wanted to know what your overall Beam Attack bonus was, you’d have to find and select a ship, then bring up several cascading tooltips, searching for the right bonus from a potentially long list.


Now all this information is available at a glance, all in one place. Bonuses are organised into what is being affected, and then where the bonus originates from. In the screenshot above, you can see that the Cosmic Contaminant's Gross Income bonus comes both from Techs (at 10% here) and also by Civilization Policy, which is adding another +5 Credits.

As the game develops there can be a lot in here, and there’s a handy scroll-bar at the bottom of this window so you can access extra columns as they’re needed.


Next up we’ve got a new Graphs tab. 4X games are data heavy and the sharper your tools for processing it, the better the experience will be. Part of the fun in any strategy game is in the planning, and planning is much more fun if you’ve got interesting and useful tools to help you out.

The Torians here are looking like they might want to go to war with us, the Cosmic Contaminant, and so it can be handy to figure out how we match up together. The new Graphs tab allows us to pick a Civilization and compare them to ours over a series of player-selectable metrics.

Here, I’ve picked some crucial information you might want to know if you need to size someone up for a war at a glance (or two), and I noticed something interesting: they’ve got a really low Food supply. This is something the CC could exploit during a limited war: by taking Core Worlds or Colonies that provide the Torians with Food, we could severely weaken them and force them to readjust their economy to make up for those losses.

This is another useful feature that will help you find and formulate strategies as you play.


If you want to compare your progress to multiple Civilizations, the Timeline is still there too, and this serves a different function in showing you each Civ’s overall progress over time.


We’ve already talked about Fleet Supply, but as a reminder, here’s where the new indicator on the main UI is.

Also on the top bar of the UI, we’ve encapsulated the lesser used Trade Resources into their own UI element on the right.


With this change, top bar shows all your most commonly used resources at a glance, with the Trade Resources tucked away for when you need them, and is a little less busy as a result.


Remember the Civilization Focus selector? Here’s where it’s located at the bottom of the Civilization Overview screen.

We’ve also made a significant change to the War Aims user interface, ensuring critical information on the progress of a war is always available as you play.


Here the Manti are engaged in two wars, with the Festron and the Korath Clan. We’re looking at the War of Conquest with the Festron, and you can see here that we’ve achieved several important War Aims: we’ve captured a Core World and two Colonies, although the Festron have so far given our mighty Fleets the slip and we’ve not destroyed a Starbase yet either.

As you complete these goals, the Progress bar will fill up, clearly seen near the bottom of War Aims UI element. Whoever fills the progress bar first will be the first to claim victory and the war ending Events will start. You can also see how many Months (or Turns) you’ve been at war, and how many Months remain before the “end the war already” Events start kicking off.


Finally, we’ve added a Mod Manager button to the main menu, which links you directly to the GalCiv IV website’s Workshop, where you can browse and add many community made mods for the game. GalCiv is a huge and expansive game and people love to mod stuff to better suit their tastes, and now it’s easier to find those mods.

Hope you enjoy the changes to the UI, let us know if you find these features useful in the comments below!

Cheers!

Today we’re going to take a closer look at two of the bigger features we’ve added to GalCiv in v3.0 “Hyperlane”, both of which complement the new map generation algorithm and really work to enhance the core gameplay of GalCiv IV.


As discussed in previous developer journals, Star Hyperlanes allow players to more easily transit from one part of the game map to another. Let’s briefly recap on what they are, how you use them, and why they’ve been added to the game.

v3.0 updated the map generator to create more realistic looking star maps, clustering stars and planets together in groups and giving more shape, and therefore more strategic gameplay, to your GalCiv games.

Before v3.0, stars were pretty evenly distributed across each sector and while some players like this even distribution, we thought that adding the option for clustered distribution would bring more of that dynamic, asymmetric gameplay that’s so fun in single player space 4X games particularly.


Players and the AI will race to explore these clusters, and may have to traverse space without any Stars whatsoever to reach new worlds and resources. Civs starting in larger clusters unopposed will grow larger faster, while those in smaller, more isolated clusters have a natural early defence against being rushed, but will have to find ways to reach neighbouring clusters if they want to expand their territory later on. Different Civilizations benefit more or less from being isolated or further from potential colonies than do others.


This is interesting for a couple of reasons: for those that don’t like playing with multiple sectors, it brings a little of that kind of gameplay into a single sector map, where some Civilizations will have access to more resources early, and others may be thrown into a close-in knife fight, battling for dominance over a small cluster with the winner taking all the best planets, and looking to expand to the next.


One consequence of the clustered star distribution patterns is that there will be areas of space with no stars whatsoever, and clusters may be quite far from one another. GalCiv 4 has already been through several points of development where Fleet travel time felt excessive, and so the Star Hyperlanes add a fun new way for Civs to traverse each sector more rapidly.


Star Hyperlanes link two Stars together, are detected as a consequence of unlocking some very early game research, and are really easy to use: just hop onto the lane at any point and you’ll receive a large boost to your Fleet’s Move speed, helping you traverse huge distances in a far shorter number of turns than it’d take if you didn’t have a Hyperlane to travel on.

This isn’t just a quick fix for a problem of slow movement speeds on large maps, and like the best kind of fixes, this one also adds more content for you to enjoy in the process: your mind should already be filled with wonder at the strategic considerations this will add to the game but I’ll give you just a few.


I touched on this in my previous developer journal but it may be that a Hyperlane’s terminating Stars could be a fast, two way link between yourself and a foreign power. If this is a potential ally, this could be a very useful way to rapidly transit your Fleets over to help them during a war. If it’s someone less friendly, like the Cosmic Contaminant, Drengin, Korath Clan, Yor or someone even worse, you’ll have to consider that Star Hyperlane are a potential vector for the insertion of enemy warships into your territory with very little warning.

In this way, Star Hyperlanes are a powerful tool, but one that cuts two ways; you’ll need to take care about who and what will be transiting down any Star Hyperlane, and I expect that they’ll factor into your strategic considerations greatly as you expand your territory in the early game, paying particular attention to the Civilization borders that form around each one.


Note that the map will generate Star Hyperlanes between clusters when there is some space to traverse between them, and while you can technically set the Star Hyperlanes to be active while deactivating the clustered star distribution effect completely, you’re unlikely to see many Star Hyperlanes as a result, as the Uniform Star distribution pattern doesn’t leave much room for them.


Both Hyperlane Frequency and Sector Layout (for Star distribution) are new options and can be adjusted to taste at game setup. If you want GalCiv IV to play as it did before v3.0, you can set Hyperlane Frequency to None, and Sector Layout to Uniform. If you want more clusters and more Hyperlanes than default, then that’s an option too!

The next huge feature change in v3.0 after the map generator improvements and Star Hyperlanes is the addition of the Fleet Supply Cap.


Where Logistics puts a limit on the amount of Ships you can add to a Fleet, the Fleet Supply Cap sets an overall upper limit on the amount of Ships you can field at any one time. As before, each Ship Class will be worth more or less points towards this total and once you’ve hit that limit, you’ll need to Decommission a Ship, or have them forcibly decommissioned by a hostile Civilization, to build any more.


GalCiv is a big and expansive sandbox game, and the idea all along has been to allow each player to play the game the way they want to. One of the consequences of allowing Civilizations to build unlimited ships is that wars tend to favour those with the higher Manufacturing and Research outputs, and while this is an expected (and to some extent desirable) situation in any space 4X, we don’t want wars to be won entirely at the strategic level, where a large Civilization that played very well during the eXplore, eXpand and eXploit phases of the game can trivially win the eXterminate phase too purely by outbuilding their opponents, flooding their territory with so many Fleets that they can’t possibly hope to deal with them all.

A knock on consequence of allowing a near limitless number of Ships to be built at any one time is that it the more Ships in play after a certain point, the less important each one becomes. Ever since the update accompanying the Warlords DLC release, we’ve worked hard to improve the auto-battler system GalCiv uses by increasing the amount of input the player has to alter the outcome of battles.


From the components you pick on each Ship, through to a Ship’s Class and Doctrine, and then the careful Fleet composition to ensure the Ships you’re bringing to a fight are suitable for exploiting the weaknesses in an enemy Fleet, we want you to have fun engaging with all that detail. With somewhat fewer Ships, you’ll need to be a little more discerning when it comes to Fleet combat, as you’ll feel every casualty even more.

With less Fleets overall, you’ll need to consider whether you can really afford to start that fourth simultaneous war or whether that’ll leave your military spread too thin to prevent enemies slipping through your defences. This change should make Military Starbases more cost effective, and overall make Civilizations that rely heavily on warfare over industrial development a bit more competitive. Looking at you, Korath Clan!

Another reason for putting an overall limit on the amount of Ships in the galaxy at any one time is one of performance. Some players were reporting late game slowdown and this should help work to alleviate that for those with computers that were affected by it.

You’ll probably be happy to note that the Fleet Supply Cap is quite generous, and it scales with map size, so you’re never feeling like you’ve got this huge space to fight over and only a relative handful of ships to do so (a problem I personally had with Simtex’s Master of Orion II in the early game particularly, an otherwise outstanding space 4X game). We’ve added some Planetary Improvements and Techs that increase Fleet Supply even more, and if you’re needing more Fleets for whatever reason, you’ll have the option to pursue those as research goals.


We’re hoping that with the new map generator and Star Hyperlanes, and the introduction of a more meaningful Fleet combat system that focuses more on quality over quantity, Galactic Civilizations IV will become even more exciting and fun for you to play. Let us know what you think of these changes as always!
