Stellaris Dev Diary #132 - Ecumenopolis and Megastructures

Hello everyone!

On this stellar day you will be able to read another of our dev diaries about the upcoming expansion - MegaCorp.

Like always I have to mention that we’re not yet ready to reveal when MegaCorp is due to being released, and that this article may contain placeholder art, interfaces and non-final numbers.

For this dev diary we will be exploring some of the new cool features in the MegaCorp expansion – namely Ecumenopolises and new Megastructures.

Ecumenopolis
“Thus shall we make a world of the city, and a city of the world”.

The city planet is here. To create a Ecumenopolis, you first need to unlock the associated Ascension Perk. The ascension perk is only available for non-gestalt empires, and requires the new Anti-Gravity Engineering technology.

Once you have the ascension perk, a decision will appear on your colonized planets. To be able to enact the decision, you need your planet to be entirely filled with only City Districts, in addition to the cost.

Ecumenolopises replace the regular districts with special districts available only to the ecumenopolis. These districts are Residential Arcology, Foundry Arcology, Industrial Arcology and Leisure Arcology. These districts are more powerful and provide a lot more jobs than regular districts. Additionally, Ecumenopolisis provide a bonus to pop growth and resource production for all jobs on the planet.

The Arcology Project is a must for anyone wishing to build a truly "tall" planet.

Megastructures
MegaCorp is releasing with 4 new Megastructures:
  • Matter Decompressor
  • Strategic Coordination Center
  • Mega Art Installation
  • Interstellar Assembly
These new megastructures will be unlocked by the Galactic Wonders Ascension Perk.

Megastructures have also received a balance pass to fit the new economy, and thus they now cost alloys to build instead of minerals.
Matter Decompressor

The Matter Decompressor works similar to the dyson sphere, but using technology far too complex to try to explain here, it extracts minerals instead of energy. It has 4 levels which provide:
Minerals: 250/500/750/1000

Strategic Coordination Center

The armored hull of the Strategic Coordination Center houses the cream of our military command, who devote their time to strategy and planning in this state-of-the-art facility. It has 3 levels and provide the following effects:
Naval Capacity: 75/150/225
Starbase Capacity: 5/10/15
Defense Platforms: 8/16/24
Sublight Speed: 5%/10%/15%

Mega Art Installation

An artistic beacon on a stellar scale, this installation inspires and represents the spirit of its creators. The Mega Art Installation also has 3 levels, but with the following effects:
Unity: 100/200/300
Amenities: 5%/10%/15%

Interstellar Assembly

A meeting place for galactic powers, increasing immigration attraction and global opinion of us. The Interstellar Assembly has 4 levels with the following effects:
Immigration Pull: 25%/50%/75%/100%
Other empire's opinion: 10/20/30/50

Don’t forget to tune in today to our Twitch stream at 15:00 CET for the Stellaris dev clash. The campaign will begin its second session, and you would not want to miss it!

That's all for this week, folks. Come back next week when we will be talking about The Caravaneers.

Will here be any update to Machine Worlds? Ecumenopolis looks pretty much like a Machine World for non gestalt empires. Also will organic hive mind get something similar?

Yes, machine worlds have new mechanics in 2.2. Hive Minds may get some sort of hive world, not yet decided.
 
If Megastructures still can't be upgraded/built more than one at the same time. It will take centuries to build/upgrade them all
 
The hype train is reaching dangerous speeds! The emergency brake broke off! There's no stopping it!

Very nice looking stuff, can't wait for a release date ;)
 
I'm looking forward to building all of these in my march to corporate dominion!

As an aside, will there be a map mode tailored to corporations, allowing them to see the spread of their influence via branch offices? (I want to fight an "underground" war against other corporations, and see how that is progressing, without caring about petty things like whose flag flies over the planetary capitol)
 
Can't help but think the "Interstellar Assembly" (aka babylon project?) will have more significance when they do the inevitable diplomacy expansion.

Is there a cap on how many Matter Decompressors you can have?

Also, what'ss the habitability of Ecumenopolei like?

Ecumenopolis is perfect habitability, much like gaia/habitat.
 
For the defense platform bonus for the Strategic Coordination Center, are those the number of additional platforms that can be built by each starbase, or are those platforms for the megastructure itself? And if the former, does the Strategic Coordination Center have any attack power like a starbase?
 
I love the idea of the Ecumenopolis! Not only will it make playing tall that much more viable but it will finally make sense to have specialized farming worlds. Also, the new megastructures sound awesome.

I'm looking forward to the update!
 
Do these new megastructures have any other requirements/limitations? Can I build the strategic command center as Fanatical Pacifists? Can I build the Interstellar Assembly as Fanatical Xenophobes?
