• Lifespan:
  • Previous "immortality" mechanics machine leaders had, where they frequently died in random accidents, have been removed.
  • Machine leaders have a starting age of 5-10 years, a base lifespan of 100 years (robots have a base of 80 years), and are affected by lifespan boosting effects.
    • "Eternal Machine", the Machine variant of "Venerable", makes your leaders of that species immortal rather than increasing lifespan.
  • Both biological empires going Synthetic and Machine empires will reset their age upon completing Ascension to reflect receiving their new bodies.
  • Gestalt councilors remain immortal.
• Habitability:
  • Machines (and robots) have replaced their +200% habitability with a habitability floor of +50%.
  • Machines, assuming they do not take a habitability restricted origin like Life-Seeded, have Dry, Wet, or Cold habitability traits, which grant +75% habitability on planets of the appropriate type and +50% on all others.
    • Machines that do not take a habitability restricted origin can immediately create templates that use the other habitability traits.
• These changes have allowed us to enable a number of previously locked Origins for Machines:
  • Life-Seeded
  • Ocean Paradise (Subaquatic Machines)
  • Post-Apocalyptic (Radioactive Rovers)
  • Void Dwellers (Voidforged)
  • Subterranean (Subterranean Machines) - Note that the habitability floor from Molebots stacks with the habitability floor of Machines, granting them a habitability floor of 100% and thus perfect habitability everywhere.
• Machine empires can now assimilate other Machines into their primary species, so you can finally force everyone to use the same operating system and charging standard.
• Robots (but not machines) are all treated as different sub-species of the same robot species.
• Added a familiar Friend after you explore Astral Rifts. (Requires Astral Planes)
• Added two new Machine Civics:
  • Spyware Directives (requires Nemesis)
  • Astro-Mining Drones (requires MegaCorp)

More Modding Documentation

Crisis Paths (Requires Nemesis or The Machine Age)

. This allows multiple crisis paths to be defined, each with their own resource, objectives and perks (or even sharing any of these as you see fit).

Authority Swaps (No DLC lock)

Back in Dev Diary #336 and Dev Diary #337, we detailed some of the Advanced Authorities available to the Cybernetic and Synthetic Ascension Paths in The Machine Age. As an example, heres the base Imperial Authority with the Imperial Feedback Advanced Authority obtained via Synthetic Ascension.

As you can imagine, these function much how tradition swaps function and offer a great deal of flexibility.

Reactive Portraits (No DLC lock)

Reactive portraits and the paperdoll layering system they use were explained in Dev Diary #342, so here Ill take the opportunity to showcase how these are handled in script. Using the Cybernetic Elf portrait as an example.
As the reactive system only depends on various triggers, this isnt required to be linked to an Ascension Path even though that was our intention for it. Additionally, due to the flexibility of scopes allowed for these triggers, reactive portraits can range from generalised customisation to incredible specific (e.g. the Chosen One God-Emperor having a unique mask/decal displayed).

Portrait Sets, Categories and Species Classes (No DLC lock)

Prior to 3.12, each Species Class had a list of portraits (and conditional portraits) defined, with 3.12 this is changing so that each Species Class will have a defined Portrait Set and that Portrait Set will have a list of portraits and conditional portraits. However, for the purposes of showing portraits in empire creation, there are also Portrait Categories. This system allows us to class the new cybernetic and synthetic humanoid portraits in the Humanoid species class while still adding their own entries in the empire creation screen to showcase the new reactive portraits.

Whats Next

The Machine Age will be releasing next Tuesday, and as there are holidays in Sweden next week, our next dev diary (The Art of the Machine Age, Part II) is planned for May 16th. At 1430 CEST today a bunch of us will be on /r/Stellaris for a Reddit AMA! (Ask Me Anything) Come ask us stuff! See you soon! The Machine Age will be arriving on Tuesday, May 7th, and is available for pre-purchase on its own or as part of Stellaris: Season 08!
