Stellaris Dev Diary #377 - MEAT SHIPS MEAT SHIPS MEAT SHIPS

Hello everybody! Welcome to our first BioGenesis development diary!

Today we will talk to about ships. That are made of meat!



Several weeks ago, Eladrin mentioned that the ship designer changes originally planned for 4.0 "Phoenix" would not be included in the Open Beta, as they’re now needed for our upcoming Q2 DLC release. We’ve since seen a fair amount of speculation as to what we might have been cooking that’d require such changes… So please allow me to introduce our Biological Ships!

MEAT SHIPS! MEAT SHIPS! MEAT SHIPS!

In BioGenesis, we are adding two distinct Biological shipsets, with unique ship classes and technology.

Our goals in adding Biological Ships to Stellaris were to ensure that they are not only different in appearance from mechanical ships (and space fauna), but also in gameplay. Thus, the key mechanical differences are:

  • When using Biological Ships, Corvettes, Frigates, Destroyers, Cruisers and Battleships are replaced with Maulers, Weavers, Harbingers, and Stingers, each of which have three growth stages.
  • Biological Ships, including Starbases, Megastructures and Stations, have their primary construction resource converted from Alloys (or Minerals) into Food and their Energy upkeep likewise replaced with Food upkeep.
  • Overwhelmingly, Biological Ship technologies fall in Society Research (Biology) instead of the familiar Engineering Research (Voidcraft).

And in classic Stellaris fashion, we’ve kept the flavor and narrative around Biological Ships intentionally vague, just enough to let you roleplay them however you like. Maybe they’re an extension of your Devouring Swarm, just another drone in space. Or maybe they’re advanced bio-machines, the pinnacle of your scientific achievement.

In order to use Biological Ships, you’ll need to select one of the shipsets during empire creation.

New shipset selector

Different types of ships prompted our UX designer to give the Shipset selector a fresh coat of paint!

Growth Cycles​


Similar to Space Fauna from Grand Archive, Biological Ships have growth stages, but unlike Space Fauna, they do not naturally progress through these by aging. Instead, these ships have a unique component slot for supplementary organs that can be researched. Generally speaking, the Juvenile and Mature growth stages will likely be occupied by Growth Organs that allow the ships to progress to the next stage.

Growth Glands!


The accumulated growth progress for ships is shown in both the ship’s tooltip and the ship details window.


Growth Progress Tooltip


Growth Progress Details

When Biological Ships are designed (either automatically or using the ship designer), all researched Growth Stages are configured as part of a single ship design. Once a Biological Ship has acquired sufficient Growth Progress, it will automatically change to using the next Growth Stage in its design. Alternatively, Biological Ships can be constructed at a shipyard at a later Growth Stage.

MEAT SHIPS! MEAT SHIPS! MEAT SHIPS!

Although all Growth Stages of Biological Ships use the same Fleet Command Limit for their ship class, later Growth Stages use more naval capacity, with the Mature stage using 1.5× and the Elder stage using 2× the Naval Capacity of the Juvenile stage.


SHIPS MADE OF MEAT​

Maulers primarily focus on short-range combat with shield penetration and high damage to armor and shields. Equipped with melee-range mandible weapons and either short-range S-slot or PD-slot weapons, these ships will form the bulk of your navy in the early game. Their unique mandible weapons have similar damage scaling against starbases and larger ships as torpedoes.

The unique Organ components that Maulers have access to are the Corrosive Fluids and Metabolic Recycler (and their upgraded versions)

Weavers are support ships, making use of unique weapons to apply powerful buffs to their allies or debuffs to their enemies.

Weaver Designs


Weavers have unique access to an array of six support components, each with six tiers that belong in the PD-slot.

Weaver Support Weapons


Weaver Suppressor Weapons

The unique Organ components that Weavers have access to are Symbiotic Amplifiers and Developmental Pheromones

Harbingers are carriers capable of deploying large amounts of strike craft and supporting them with point defense or long range missiles.

Harbinger Designs

Strike craft for empires using Biological Ships are deployed in greater numbers per fighter wing, but have reduced hull points and armour instead of shields.

Biological Strike Craft

The unique Organ components that Harbingers have access to are Chitin Growth Regulators and the Incubation Matrix

Stingers are powerful late-game warships, equipped with multiple XL weapons or capable of unleashing heavy broadside barrages.

Stinger Designs

As each of the different Growth Stages of each of the classes of Biological Ships can be built at a shipyard, we’ve taken the opportunity to implement collapsible headers when selecting which ships to build.

Shipyard Headers

This works for mechanical ships and space fauna too!



Since Biological Ships have their own weapons, armour, shield and core components, we’ve gone through and ensured that the technologies use the appropriate icons depending on if you are using a Biological shipset or not.

Technology Swaps


Modding Notes​

As part of the work required to implement Biological Ships there have been a lot of changes to how ship components are scripted. Here’s some highlights:
  • class_restriction, size_restriction and slot_restriction are deprecated in favour of using the possible and potential trigger blocks instead.
  • Core Components now have an upgrade_path parameter, components that have the same upgrade path are shown on the same row.
  • Ship components now support the show_tech_unlock_if = { } field, like buildings.
  • New targeting parameters:
    • use_ship_main_target: if yes, overrides target_type and target_focus when ship's main target is within range, default no
    • target_type (target_enemies (default) / target_allies / target_controlled / target_own)
    • target_focus (single (default) / spread)
    • target_type: only valid if component_set has affects_target_type = yes
    • target_focus: only valid if component_set has affects_target_focus = yes
  • New parameters for weapons:
    • on_hit: apply effects to target on hit. Scope = ship (target), from = ship (shooter)
    • hide_damage_values_from_tooltip = yes/no # If yes, it will hide Damage and Average Damage from weapon component tooltip (default = no)

Next week we’ll be looking at Ascension, Traditions, and Advanced Governments. See you then!

PRIME CUTS FROM ART!​


They're made out of meat.


  Meat?



Meat. They're made out of meat.



Meat?


There's no doubt about it. We picked several from different parts of the planet, took them aboard our recon vessels, probed them all the way through. They're completely meat.


That's impossible. What about the radio signals? The messages to the stars.


They use the radio waves to talk, but the signals don't come from them. The signals come from machines.


So who made the machines? That's who we want to contact.


They made the machines. That's what I'm trying to tell you. Meat made the machines.


That's ridiculous. How can meat make a machine? You're asking me to believe in sentient meat.


I'm not asking you, I'm telling you. These creatures are the only sentient race in the sector and they're made out of meat.


Maybe they're like the Orfolei. You know, a carbon-based intelligence that goes through a meat stage.


Nope. They're born meat and they die meat. We studied them for several of their life spans, which didn't take too long. Do you have any idea the life span of meat?

Lots of cool stuff. I have to admit I’m a bit out off by the growth mechanics though perhaps I don’t understand them properly in this context. With fauna I found it quite a chore to maintain tidy and organised fleets as new fleets would randomly pop out of old ones, it was incredibly expensive to build non juvenile ships, and overall just didn’t feel worth it for how weak they were. I love the idea of organic ships but not keen on the messy headache of not having standardised fleet compositions. Especially as pausing growth in fauna was just undercutting yourself.

Are there any QoL changes for fleet management here?
The dev diary mentions that all growth stages use the same fleet capacity, meaning your 20 babies at the beginning of the game could grow into 20 adults without ever becoming 21 nor more
HOWEVER, your total capacity will increase appropriately, so better make sure you don't fill it with babies which will then double

This... is really, really cool.

And available to any empire I want to do it with.

And extremely gameplay-different, so that's a huge bonus too.

One question, possibly with an obvious answer. Say I have an 'Adaptive Spore Launcher" and a damaged ship in the system, but my fleet isn't in combat - does it know to use that for repairs out of combat? On other fleets? ...on the local starbase, or the new megastructure?

They're living ships, they will repair out of combat anyways

If an empire chooses to use meat ships and then they make a federation with a federation fleet or become the custodian/emperor and make the GDF, will they still use meat ships for that, would they have the option to use either meat ships or normal ships, or would they only use normal ships?

I really love those powerful X slot weapons! I'm eager to see details about NEW X weapons! Is there any juicy details like range/damage ?
 
Actually, if you examine the screenshots closely, you'll discover they're made of apples.

In any case, inform your corporate overlords that I will happily spend money on more bio shipsets and indeed more non-bio shipsets. Money for the taking over here.

How connected with the other biology technologies are the bio ship technologies? Having ships made of meat is great at all, but if the technologies involve in upgrading, producing, and maintaining them aren't in some way related to biotechs like genetic engineering and cloning, then they are kind of just mechanical ships with a few quirks.
From the sound of it, bioships will still use regular technologies for power plants, weapons, etc., but with text changes (e.g., instead of a fusion generator, you have a fusion-based metabolism). They aren't Biology techs for the same reason their regular versions aren't Voidcraft: you need to master the principles of physics behind whatever phenomenon and then making the actual laser cannon/beam emitting organelle is a simple matter of engineering that you don't need a research project for.

As far as flavor, they explicitly want it to be open to player interpretation whether a given empire's bioships are single organisms genetically engineered for a purpose, like the Zerg, or clusters of symbiotic organisms that are melded together by engineers, like the Yuuzhan Vong, or even biological frameworks that have "regular" technology implanted within them like the Polaris.

Is there any mechanic to prevent you from making the Juvenile variant dirt cheap and then “growing” into a fully equiped (and much more expensive) Mature ship?

Ah great. Makes sense I guess because they're not changing class. Increasing over naval cap seems a much easier and better problem than the fiddliness with fleets.
