The Arcology Project decision now starts a situation for the planet to transform the planet into an Ecumenopolis, so you can continue creating buildings on your planet while it transforms just like Machine or Hive Worlds. Hive and Machine worlds can now be improved!

If you have an existing save, please use the "ACPS Mod Configuration" decision to update the new features, otherwise you may be missing content!

The cost for enacting the project is reduced to 2,000 Alloys and 200 Influence. The cost difference is made up with a situation upkeep costs.

• Standard Deadlines: Finishes in 10 years if used exclusivly
  
• Accelerated Deadlines: Finishes in 7 years if used exclusivly
  
• Extreme Deadlines: Finishes in 5 years if used exclusivly
  

Most of the situation choices are tied to your Ethic, Civics, and Origins selections!

The Research / Education options for individual empires are limited based on the Leaders on your council instead of Ethic, Civics, and Origins. You need 2+ associated leaders on your council to prompt the option (Ruler does not count). See Empire Design Spoilers Here

Ascension Cities are not shown in the images above as there is too much variation. They essentially give you an extra ascension building or planetary feature (e.g. nanites), including all its bonuses, as a Planetary Deposit.



After terraforming (or finding) a Hive or Machine world, you now have the opportunity to improve it via the "Improve Machine World" or "Improve Hive World" decision.

All of the choices are driven by origins and civics (hive occasionally has an additional lithoid vs biological requirement)
See Empire Design Spoilers Here

The Ascension deposits for Hive and Machine worlds are similar too the ECU ones.

Enacting the costs 500 energy and 150 influence, and the Deadline approaches cost cost variable amounts depending on if you're a machine, organic hive, or lithoid hive.

• Standard Deadlines: Finishes in 6 years if used exclusivly
  
• Accelerated Deadlines: Finishes in 4 years if used exclusivly
  
• Extreme Deadlines: Finishes in 2 years if used exclusivly
  

If you conquer or find a premade ecumenopolis without the improvements from this mod, you can launch a refurbishment situation to update the old ecumenopolis to be shiny new and improved!

Enacting the project is free, and the Deadline approaches cost the same as the Construction Situation, but without minerals.

• Standard Deadlines: Finishes in 2 years if used exclusivly
  
• Accelerated Deadlines: Finishes in 1.5 years if used exclusivly
  
• Extreme Deadlines: Finishes in 1 year if used exclusivly
  

Megacorp is needed if you want Ecumenopoli
Megacorp is needed if you want Relic Worlds
Utopia is needed if you want Hive Worlds
Synthetic Dawn is needed if you want Machine Worlds
