Overlord Expansion Features
###################

  • Three new advanced subject types called Specialist Empires have been introduced, which excel in certain areas while having deficiencies in others.
    • Bulwark - A bastion of defense that leaves basic resource acquisition to others.
    • Prospectorium - Excels at resource acquisition but has weaker research.
    • Scholarium - Specializes in research but relies on their allies for military support.

Similar to how Federations advance or degrade based on Cohesion, Specialist Empires improve based on loyalty, gaining additional perks and strengthening their bonuses and penalties as they level up through three tiers.

  • New Constructions and Megastructures
    • Hyper Relays - Chained together, Hyper Relays permit high speed fleet travel and projection of effects to systems connected via the network.
    • Orbital Rings - Built around your worlds, Orbital Rings act similarly to Starbases and allow further development or defense of these core planets.
    • Quantum Catapult - The galaxy is within reach as the Quantum Catapult lets you fling ships across the galaxy, though with questionable accuracy. Yeet.

  • New Enclaves
    • Salvager Enclave - A generally friendly bunch of tinkerers, obsessed with engineering, battle debris, and restoring or scrapping antiquated ships.
    • Shroudwalker Enclave - Disciples of the Shroud, the Shroudwalkers can call upon its powers to create shroud tunnels, or to attempt to divine the future - if you dare.
    • Mercenary Enclave - Empires can release a fleet to create a self-reinforcing Mercenary Enclave that brings dividends back to their patron. But remember, business is business, and concepts like loyalty don’t pay the bills.

  • New Origins
    • Imperial Fiefdom - Your first steps into space were brutally short. Immediately subjugated alongside several others by a powerful and decadent overlord, you begin the game as a Specialist Empire of your choice.
    • Teachers of the Shroud - Your civilization was identified as a civilization of interest long ago by the Shroudwalkers, who carefully nurtured your development as their visions instructed. Your species begins with the Latent Psionics trait and in contact with the Shroudwalker coven.
    • Slingshot to the Stars - The Slingshot to the Stars origin explores how a nearby Quantum Catapult could shape your civilization. The histories of your people are filled with tales of brilliant lights flashing across the sky before the long seasons of darkness.
    • Subterranean - The underground homes of Subterranean empires grant defensive and mining benefits while allowing them to avoid hostile environments on the surface, at the cost of slower expansion.
    • Progenitor Hive - Hive-Mind only (also requires Utopia). The hive relies on the presence of the powerful offspring of the progenitor, guiding the hive’s will with incredible skill. Protect them well, for the drones are lost without their presence.

  • New Ascension Perk - Profit from conflict with the Lord of War Ascension Perk.

  • New Galactic Community Resolutions - Debate the place of Mercenaries and the rights and responsibilities of subjects and overlords with three new lines of Resolutions.

  • New music tracks - 4 new songs added to the game and Original Soundtrack

  • New Achievements - Show the galaxy who leads them with 11 new Steam achievements.

###################
3.4 “Cepheus” Features and Changes
###################

  • Situations - Include a new system for tracking and interacting with ongoing stories in your empire
    • Deficit Situations will trigger if you have a negative monthly balance of a resource and it runs out.
    • Revolt Situations may trigger on planets with low stability, overhauling previous rebellion mechanics.
    • Machine Uprising Situation replaces old Machine Uprising event (requires synthetic dawn)
    • Leviathan Situations celebrate your great triumphs when besting such mighty beasts.
    • Other narrative Situations have been implemented to add even more flavor to your campaigns.

  • Negotiation of Subjugation Agreements - The terms of subjugation agreements can now be negotiated and changed. Some terms that can be altered include:
    • Integration Possibility
    • Diplomatic Freedom
    • Ability to Expand
    • Resource Subsidies and Tithes
    • Defensive and Offensive War Responsibilities
    • Overlord Holding Limit
    • Sensor Sharing

The default terms of some contracts have been updated to fit the new system, and some specific terms or settings require Overlord.

  • Allegiance Wars - The Pledge Secret Fealty diplomatic action has been added, which allows subject empires to secretly plot with a new overlord. This permits a War of Allegiance - a new war goal that allows empires to fight other Overlords for control of subjects that have pledged secret fealty to them. All subjects that have pledged secret fealty will turn on their former overlord during the war.

  • Subject Changes/Improvements:
    • Overlords can now build a holding on Subject Planets (holdings may require certain civics, origins, or DLC)
      • Overlord Garrison
      • Emporium
      • Aid Agency
      • Ranger Lodge - Environmentalist Civic
      • Noble Chateaus - Aristocratic Elite Civic
      • Recruitment Center - Citizens Service Civic
      • Gaia Seeder Outpost - Idyllic Bloom Civic (requires Plantoids)
      • Tree of Life Sapling - Tree of Life Origin (requires Utopia)
      • Dread Outpost - Reanimators Civic (requires Necroids)
      • Sacrificial Shrine - Death Cult Civics (requires Necroids)
      • Reemployment Center - Permanent Employment Civic (requires Necroids and Megacorp)
      • Franchising HQ - Franchising Civic (requires Megacorp)
      • Communal Housing Outreach - Shared Burdens Civic (requires Utopia)
      • Organic Haven - Rogue Servitor Civic (requires Synthetic Dawn)
      • Experimental Crater - Calamitous Birth Origin (requires Lithoids)
      • And twelve more holdings with Overlord.
    • Subjects now have a Loyalty value, rather than loyalty solely depending on their opinion of their overlord.
    • Subjects’ ethical compatibility with their Overlords may result in a monthly loyalty bonus or penalty.
    • Having more than one subject adds a monthly loyalty penalty to all subjects, which can be worked around with various civics and or the Shared Destiny ascension perk.
    • Subjects and Overlords have a bonus to infiltration growth on each other.
    • Operations on your subject or Overlord are reduced in difficulty.
    • Additional trade deal options between subjects and Overlords have been added.
    • Releasing a sector as subject now grants an initial 100 intel on that subject.
    • Integration is disabled by default.
    • Sectors released as subjects can now inherit the following origins from their parent empire, where appropriate - Progenitor Hive, Subterranean, Void Dweller, or Calamitous Birth.
    • Gateways (and Hyper Relays) can now be built in subject space.
    • AI Subjects of Player Empires now receive AI bonuses as if the difficulty level of the game were one level lower, rather than losing their bonuses entirely.

  • MegaCorp Improvements as both Overlords and Subjects:
    • Empires that are the target of Impose Ideology wars or those created from Status Quo peace deals are no longer rival Megacorps, but instead Oligarchies with the Merchant Guilds civic.
    • Corporate Overlords can establish branch offices in their non-corporate subjects without having to sign a Commercial Pact. Likewise, corporate subjects with a non-corporate overlord can open branch offices in their overlord and fellow subjects.

  • Major improvements to Planetary Automation:
    • Planetary Automation scripts based on designation are now more focused regarding what they build.
    • Right clicking on the planetary automation button will now open a menu which allows you to customize your focus of planetary automation: for instance, as well as the designation based focus (“build more minerals buildings”), it lets you enable handling of amenities and housing, crime, as well as more specialized building options such as psi corps.
    • Sector automation and planetary automation have been unified into the same system (sector automation will activate planetary automation for all planets in the sector, and assign relevant planetary designation types to the planets unless overridden.)
    • Additional planetary or sector automation options have been added:
      • Added a Unity sector automation setting
      • Forge, Factory and Industrial designations are now available on Ring Worlds
      • Fortress world designation is now available on Machine Worlds and Hive Worlds

  • Automatic Resettlement Improvements
    • The Auto Resettlement formula for picking which planet pops will be resettled to has been improved: it is now easier to steer pops towards your capital and other special worlds (e.g. ring worlds).
      • Pops will now pick which planet to auto-migrate to based on which planet has the most free jobs, rather than the least. They also now take free housing into account better
      • "Ideal" worlds such as ring worlds, gaia worlds, hive worlds and machine worlds now have a 50% higher score when pops are deciding where to automatically resettle to. So they are more likely to want to move to your newly-founded ring world, for instance. Capital world planet designations also have a +10% score, and freshly founded colonies have 25% from their designation.
    • The resettlement tooltip (found by hovering over unemployment in the planet view) now provides far greater insights into how the system works, including showing the reasons pops cannot automatically resettle or the planet they are most likely to resettle to.
    • The outliner has been updated so planets with unemployed pops that are auto-migrating are now shown a yellow suitcase. The red suitcase should only appear if the planet actually requires your attention to resolve the unemployment problem.

  • Various AI improvements with a focus on military behavior - full details in section below

  • Added 73 new flag emblems, 63 new flag backgrounds and 47 new flag colors (including white!).
    • 12 new emblems each to match the Plantoid, Lithoid, Necroid, Aquatic, and Imperial shipsets
    • 6 new emblems for the Corporate and Legion categories
    • 1 new emblem for Paradox Arctic in Umeå

  • Added improved human portraits, with 5 phenotypes, 5 eye colors, 7 clothing styles and many, many hairstyles (including facial hair)!

  • Added Japanese and Korean language support.

###################
Balance
###################

  • Subjugation casus belli is now automatically granted towards inferior empires.
  • The Parliamentary System civic now allows factions to be generated much earlier in the game.
  • Defense Platforms now have increased range, fire rate, tracking, and hull points, and are faster to build.
  • Base market price for slaves doubled from 500 to 1000 energy credits to make selling pops more viable. Slave traits cost Modifiers for the Slave Market have been increased by roughly 10 times for positive ones and 4 times for negative traits.
  • Endgame Crises can now happen after 25 years rather than 50 of the End Times.
  • The Plunder wargoal now increases the chance to steal relics (that aren't the Galatron) to 50%.
  • The Numistic Administration trait no longer provides an increase to energy output, it now provides a +33% output to trade value from jobs.
  • Removed the requirement to have an upgraded capital building in order to build research labs or rare resource manufacturing buildings
  • The Shared Destiny AP no longer affects subject integration cost or trust, instead removes the monthly loyalty penalty from having multiple subjects. Additionally, it can now be taken by Corporate empires.
  • The Grasp the Void AP now grants increased draw weight for FTL travel techs.
  • The Unbidden can no longer spawn in pulsar systems (as the star will disable their Dimensional Portal's shields)
  • Resistance is Frugal no longer grants your strongholds a unity production of 3, instead it gives you 0.5 unity for each defensive army you have.
  • Strength of Legions and Warbots now start with rank 3 Admirals and Generals.
  • Espionage Operations now cost Influence to start rather than Energy Credits. Costs have been reduced by a factor of 10.
  • Low Military Intel is now gained at 30 Intel instead of 40 and Medium Military Intel is now gained at 60 Intel instead of 70. The effects of Medium and High Military Intel have been swapped - medium now allows you to view ship loadout, high now grants visibility of location of military fleets.
  • Added a nanites deposit to the Scavenger Bot system so you can use the reward you get for killing it.
  • The Subterranean empire from the Seismic Disturbances event chain now spawns with the new Subterranean origin.
  • Numistic Data Modeling technology now provides +5% Trade Value.

###################
AI
###################

  • With sufficient Intel, there will now be a notification that the AI is planning to declare war on the player.
  • Fixed a variety of AI military fleet behavior issues, including:
    • AI will be better at merging fleets where that makes sense (e.g. during peacetime, or when they have the same mission)
    • Fixed issues where your allies would follow your take point command even though they were not hostile to your targets, and several other issues with take point and follow fleet behavior
    • AI will now more actively engage hostile crises if they or their allies have been attacked by them
    • Fixed an issue where an AI fleet could get trapped in an enemy system by a disabled starbase. It will now approach the starbase to capture it.
  • AI will now enable buildings that have been disabled.
  • AI will now scale the production of rare resources according to the size of their economy.
  • Moderately reduced the frequency of how often AI will sell slaves on the market.
  • AI will now only consider jobs producing at least 3 amenities when doing the planet amenity balancing logic.
  • AI will now declare "death spiral status" if they have 0 minerals and a negative mineral income. Jobs consuming minerals will be deprioritized until a sufficient mineral income has been reached and the empire can start rebuilding itself.
  • The AI will now wait for a period of time before changing planet designations when taking over a player empire in multiplayer.
  • AI members of a federation will no longer propose a vote on a law change that has been proposed in the last 10 years by anyone in the Federation.
  • The player now gets a notification when the AI has recalled their embassy.
  • AI will now only propose an embassy if they have a positive +50 relation and remove their embassy if they have lower than -50
  • The AI is now better at dealing with non-standard colony ships (e.g. private colony ships, Lithoid colony asteroids).
  • AI will now sell resources more aggressively to buy what they need in order to recover from death spiral type situations.
  • Fixed several issues with Galactic Community voting, AI will no longer propose resolutions against their alignment, AI can recall their proposals or vote against their own proposals in some situations where it makes sense. Tooltips will now show the reasons an AI empire is voting the way they are.

###################
UI
###################

  • Added new section in outliner for loaned out fleets (lease timer and its tooltip).
  • The alert for diminishing resource stockpiles now properly only lists resources which you will imminently run out of.
  • Added tooltips for agreement presets and specialist types to the Agreements view.
  • The outliner will now tell you about blockers you can remove if you are approaching the planet's carrying capacity and therefore suffering growth penalties.
  • Improved the layout of the Host DLC icons and surrounding elements in the Multiplayer Lobby.
  • Moved the “Copy Server ID” functionality to a separate button in the multiplayer lobby.

###################
Performance & Stability
###################

  • Optimized calculations for whether you are in breach of any galcom resolutions, which should provide a boost if many sanctions have been passed.
  • Improved the performance of using triggered economic category modifiers.
  • Improved performance of bypass handling in pathfinding to account for the fact that there are now many more of them in the galaxy (via hyper relays).
  • Adjusted various ship textures for improved performance.

###################
Other Improvements
###################

  • Significantly improved pop job assignment weightings:
    • Automatic scripted handling of resource output, trade and amenity bonuses and penalties from traits, i.e. pops with the better traits for the job will more reliably take the job. This eliminated many errors where we had imperfectly attempted to achieve this result in a much less robust and more verbose way.
    • Weighting now takes into account output penalties from low habitability
    • If you are in deficit, jobs producing that resource will now be weighted significantly higher, so your pops won't ignore mining jobs while your empire burns for lack of miners.
  • Added new Subjugation War Terms policy, which sets the default Agreement Terms used when subjugating other empires through war.
  • You can now nominate other empires to Custodianship, provided they meet the requirements.
  • Idyllic Bloom has been improved by allowing construction of the Gaia-Seeder buildings (and holding!) to be built on a wider range of planet types, in exchange for increased upkeep, depending on the empire’s terraforming technology. In addition, the civic can now be combined with the Life-Seeded and Shattered Ring origins. Finally, Idyllic Bloom empires start with a Phase 1 Gaia-Seeder on their capital where appropriate.
  • Shroud Entities that propose Covenants will now prefer empires that have ethics or civics that match their outlook. The End of the Cycle is more likely to offer a Covenant if another empire is a level 5 crisis.
  • Several improvements to Baol/Zroni spawning: they will no longer spawn arc sites in your capital system, one of the Baol arc sites is now vastly less likely to spawn in someone else's territory, and they are a bit less likely to all spawn in a heap in neighboring systems.
  • Modifiers giving administrator output now correctly reflect the sort of administrators the empire uses.
  • Individual names for game objects can now be localized, allowing players to read names in their own language.
  • Renamed the Corporate and Gestalt versions of Catalytic Processing to Catalytic Recyclers and Organic Reprocessing respectively.
  • Quget.

###################

  • Fixed the ship reinforce button sometimes telling you repeatedly that there are no available shipyards.
  • Enrolled engineers in the Curator's seminar on "Ringworld Repairs and You!" (Repaired ringworlds from the shattered ring origin and alpha refuge no longer have display issues).
  • The shard will no longer inform the player twice about its demise.
  • Fixed an issue where the list of supporters for an upcoming resolution in the Galactic Community didn't refresh correctly when clicking between two Resolutions with the same number of supporters.
  • Fixed armies being mistaken for buildings in some build queue tooltips
  • Here Be Dragons empires are now less amazed to see an Ether Drake (it's still a remarkable occurrence, but not something the likes of which they've never seen before)

  • Sectors released as subjects by empires with the Pompous Purist civic will have the civic removed.
  • Fixed some issues with AI Uprising Empires, where the created empire would have unreasonably large fleets, but could also immediately go bankrupt in several resources.

Moddability Changes in 3.4 ‘Cepheus’ by @Caligula Caesar

I’m going to keep this one fairly brief, by my standards. Recent updates have given modders plenty to get their teeth into, and 3.4 is no different. We already described the Situations system a few weeks back, which will doubtless see much use and abuse from modders, so I’ll focus on other scripting language changes.

The biggest improvement that springs to mind is in the field of modifiers. In triggered modifiers, you can now define a “mult” value, which lets you apply a modifier or script value to that triggered modifier:
Code:
triggered_pop_modifier = {
    potential = {
        NOT = { is_same_species = owner }
}
    modifier = { pop_citizen_happiness = 1 }
    mult = modifier:non_main_species_happiness_mult
}

As you can see, I’ve defined a modifier that we do not have in the game there. That is because we can now define our own ad hoc modifiers in script, for instance:

Code:
non_main_species_happiness_mult = {
    icon = mod_planet_happiness_mult
    percentage = yes
    good = yes
    category = pop
}

This modifier will of course only do something so long as it is applied somewhere, but nowadays there’s plenty of places where that is possible (everywhere that script values are valid). For instance, we have refactored species traits’ amenities and trade output from jobs to use this system, which cut down on the effort it takes to tweak their numbers (and let us track down a few bugs in that regard).

As a low-key but quite nice improvement, you will also no longer get load order errors where certain modifiers do not work in certain contexts (e.g. ethos modifiers in traits).

That’s not all we have done. Developing Overlord naturally provided some opportunities to rework old systems. For instance, thousands of lines were saved in the scripts for enclaves by using the new “event inheritance” system. With this, an event can be specified to inherit properties from another via “base = <some_event_id>”. Then, various properties can be overwritten via “desc_clear”, “option_clear”, “picture_clear” and “show_sound_clear”. Basically, this lets us inherit the behaviour of a given event while changing its flavour.

The list goes on. A new common/tradable_actions folder now lets you define custom actions that you can trade with other empires. For instance, subjects can pledge loyalty to their Overlords in return for other benefits. The folder is also extensively documented:

Speaking of the AI and diplomacy, diplomatic actions are now a little bit more controllable from script. While they (and AI logic surrounding them) are still handled to a significant degree in code, additional reasons for the AI to accept or decline the proposals can now be scripted in an “ai_acceptance” field, while a “should_ai_propose” field lets you block the AI from proposing it.

Finally, something that modders need to know about is our changes to synced localisation. Or rather, the fact that we have completely removed it. This means that, everywhere where it was used, we now use the normal localisation system instead. There are several advantages of this:
  • Multiplayer will now work, even if one player is playing in Chinese and one player in English (this does not currently work)
  • It is theoretically possible to translate all names into other languages now. (Unfortunately, however, I can’t promise that we’ll ever do that, because European languages all have complicated grammar rules, and we have yet to work out a reasonable way to deal with them. But still, the possibility is pretty cool).

Unfortunately, there are also some complications, which can be summed up as: we need to save a property as it is at the time something is named (i.e. the property may change later - but this should not affect what it localises as), and also make sure that it is localising correctly no matter which language you are playing in.

Basically, this means that if you want to use bracket commands in setting names, you need to register it in the place where you are setting the name, e.g.:
Code:
set_name = {
                    key = "NAME_Absorbed_Species"
                    variable_string = "[Root.GetSpeciesNamePlural]"
                }
 NAME_Absorbed_Species:0 "Absorbed [Root.GetSpeciesNamePlural]"

Empire names in the random_names directory have a new “lookups” line to serve this purpose:

Code:
# Imperial Spiritualist 2
empire_name_format = {
    random_weight = {
        factor = 0
        modifier = {
            add = 1
            has_government = "gov_theocratic_monarchy"
            is_pirate = no
            is_primitive = no
            NOT = { is_country_type = fallen_empire }
            NOT = { is_country_type = awakened_fallen_empire }
        }
    }
    lookups = "<imperial_spi> [This.Capital.GetName]"
    format = format.imp_spi.2 # <imperial_spi> of [This.Capital.GetName]
    noun = format.homeworld # [This.Capital.GetName]
    prefix_format = format_prefix.imp_spi.2 # [This.Capital.GetName] <imperial_spi>
    # Empire of Earth
}

In cases where names were defined inline in script, which is quite common in mods, it will likely continue to work as it used to (so long as no square bracket commands are used). I can’t entirely vouch for this, since we don’t use this functionality inhouse as it would break Chinese (and now also Korean and Japanese) translations, since they have always translated names. It may also cause issues if the name you are setting something to is a key that is localised, but which you did not intend to refer to… (N.B. name lists now also use localisation keys).

As a word of caution, each square bracket command we make available has to be defined to work in the C++ code. We have tried our best to cover all the cases which one could want to use, but there may be some we’ve missed (in this case, the error log will complain about invalid property “GetXPersistent”). If there are any particularly egregious cases we turn out to have missed, please file bug reports and we’ll see what we can do!



But wait, there’s more, from @Eladrin :

This week’s origin reveal from Nivarias is the Progenitor Hive!

1651752843139.png


In the beginning, the Progenitor was.

Life on your homeworld was harsh and competitive, yet still the mighty Progenitor expanded its territory. Running such a vast dominion soon grew untenable, so the Progenitor created the first Offspring. In time, it became apparent that the Offspring could not manage alone. In turn, they produced menial drones to assist in taming our home.

As you took your first tentative steps across the stars, the Progenitor sequestered itself into a specialized nest. Endowed with greater, streamlined control, you are now ready to spread the Progenitor's influence to all the stars of the galaxy - for the Progenitor was, is, and will be.


The Progenitor Hive origin is a new Hive Mind origin coming in Overlord, and as such it also requires Utopia to play.

The hive relies heavily on the presence of powerful Offspring. While they are near, the hive thrives and functions with great efficiency.

Offspring Vessels can be included in your fleets, providing an aura that cancels out the inherent penalties of your ships, providing a net small bonus. You are limited in the number of Offspring Vessels your empire can support at any given time, based on your overall naval capacity, similar to the Titan limit. The Offspring Vessels share a pool, with larger ships taking a greater portion of the pool.

1651752853800.png


There’s also a starbase building to protect your empire space, which provides greater benefits than the ships.

1651752863307.png


The Offspring Nest replaces the Spawning Pools of regular hives, providing additional bonuses. You’ll want one of these on each of your planets.

1651752871020.png


Make sure someone is working the Offspring Drone job, since otherwise the directionless menial drones on your colonies face difficulties.

1651752877859.png


All employed leaders within a Progenitor Hive, passively gain experience at a steady rate, gaining skill levels at a much faster rate than leaders of other empires. On average, with no experience boosts or other sources of experience, they will passively gain a level about every (1.5 * level they’re going to) years.

Unlike other hives, the Progenitor is able to release sectors as vassals, placing the fate of the sector in the tendrils of an Offspring which is promoted to Progenitor status and becomes the ruler of the new empire. Progenitor subjects released inherit the Progenitor Hive origin from your empire, with all the bonuses and penalties that it entails.

1651752885012.png


Should you have a subject that is not a Progenitor Hive, you can build an Offspring Nest on their world, providing some much needed oversight to their dro- er, workers. They’re basically the same thing, right?

1651752892011.png


There’s also one other (non-Progenitor Hive related) holding to reveal!

Overlords with the Environmentalist civic can build a Ranger Lodge, which reduces consumer goods usage on the subject planet but also creates a Nature Preserve blocker, which cannot be removed as long as the lodge exists.

1651752900413.png


1651752906885.png


The Ranger Lodge can only be built on natural planets that have districts available to block, and cannot be built on Ecumenopolies, Hive Worlds, Machine Worlds, or Relic Worlds.

I'd work at Paradox if they'd be willing to move their HQ along with their entire dev team over here to the US.

It's a good deal, PDX. I won't make this offer again.

I don't think moving from a 1st world country to a 3rd world country is a good deal, but that's just me :)

No new Dev Diary today?

It usually drops between 13:00 nd 17:00, so still plenty of time. And I think it will drop the exact moment Overlord goes live.

hmm, I don't recall seeing discussion of this previously, did I miss it somewhere? I've been asking for something like this (AI using the market more effectively) in various bug reports for a long time now. Do we know any details of this change, the logic to how it works?

This could be a real big improvement to difficult situations for late-game AI. Thanks @Offe
I forgot to include a lot of things in the dev diary because it was already quite long and also because there was a big delay in writing the dev diary and making the AI changes.

The big thing in this specific change is that AI could end up in situation where it would sell low amounts of resources each month, but due to having a large deficit it would not be enough for them to build anything. For example they are -200 minerals per month and buy 100 each month on the market.
