Stellaris Dev Diary #100 - Titans and Planet Destroyers

Hello everyone and welcome to this very special triple digit Stellaris development diary! Today's dev diary marks the start of talking about the Apocalypse Expansion that will be accompanying the 2.0 'Cherryh' update. We still can't give you an ETA on the release of either, and there's a fair bit to cover in the expansion before then, but we're getting closer. As this is the start of talking about paid features, I just want to take a moment to reiterate that everything talked about in dev diaries 91-99 (with the exception of Dev Diary #95 which was about Humanoids) were about the Cherryh update and all features and changes mentioned in these previous dev diaries are part of the free update, NOT the expansion. Everything mentioned in this dev diary will be part of the paid Apocalypse expansion, however. Please note that some of the screenshots in this dev diary feature placeholder art and icons.


Planet Destroyers (Apocalypse Feature)
As mentioned all the way back in Dev Diary #50 and again in Dev Diary #69, Planet Destroyers have been on our wish list for quite some time, but wasn't something we could make work with restrictive nature of the old warscore system. Now that this is no longer a concern thanks to the new war system we talked about in Dev Diary #93, we finally have our chance to implement this beloved sci-fi staple.

Planet Destroyers come in the form of a new ship class called a Colossus. Though nominally a military ship, the Colossus has no actual fleet combat capability, but is instead a single massive weapon solely dedicated to the purpose of laying waste to enemy planets. To build a Colossus, you must first already know how to build Titans (more on those below) and then take the Colossus Project Ascension Perk, which unlocks a special project to research and design your first Colossus. Each Colossus mounts a single World Devastator-class weapon, and during the course of the project you will be given the option to choose which such weapon you want to focus on, with five potential options to choose from:
  • World Cracker: Shatters a planet, leaving behind a broken debris field that can be mined for resources. Available to non-Pacifists.
  • Global Pacifier: Encases the planet in an impenetrable shield, permanently cutting it off from the rest of the galaxy. A research station can be built to study the planet afterwards.
  • Neutron Sweep: Destroys most higher forms of life on the planet but leaves the infrastructure intact for colonization. Available to non-Spiritualist, non-Pacifist empires.
  • God Ray: Converts all organic Pops on the planet to spiritualist and destroys all machine/synthetic pops, as well as massively increasing spiritualist ethics attraction on the planet for a time. Available to Spiritualist empires.
  • Nanobot Dispersal: Assimilates all Pops on the planet, causing it to defect to your empire with its newly cyborgized population. Only available to Driven Assimilators (and thus requires Synthetic Dawn as well).

(Weapon icons are placeholders)

Additional types of World Devastator weapons that are potentially available to your empire can be researched as rare technologies after finishing the Colossus project. Once the project is complete, you will be able to build a Colossus at any Starbase with a shipyard where you have the Colossus Assembly Yards building built. Once built, the Colossus functions similar to a civilian ship, in that it is own fleet, and cannot be merged with other fleets. Each empire can only have a single Colossus active at the same time, but can build a new one if their active one is destroyed.

Colossi have no conventional armaments (though we are discussing a few medium/PD turrets to them), and their real purpose is to target enemy planets. When a Colossus is ordered to target a planet, it will travel straight towards it, ignoring enemy ships entirely even if they fire on it. The Colossus will travel to the planet, take up position and begin charging its weapon. The weapon takes quite some time to charge, giving enemy fleets a chance to try and destroy the Colossus to stop it from firing (though Colossi naturally can take a great deal of punishment, they are not invincible). Once the weapons is fully charged, it will fire, executing its effects (as described above) on the hapless planet. The Colossus is then free to continue on to the next planet if you so wish. Most Colossi weapons can only target planets owned by empires you are at war with, though some of them can target primitive worlds and the World Cracker can be used on uncolonized rock-type worlds (but will not always generate a mineral deposit in that case).

(Animations & interface are partly WIP)

The system for creating World Devastator weapons is fully scriptable, and modders will be able to create their own planet-destroying/changing effects.

Titans (Apocalypse Feature)
Titans are another new ship class available in the Apocalypse expansion, but unlike the Colossus they are much more like conventional warships. Titans are researched through a regular tier 5 technology, and can be built in any Starbase with a shipyard and the Titan Assembly Yards building. Titans are massive flagships that come equipped with an array of heavy long-ranged weaponry and layer upon layer of shields and armor. Their front section has a single Titanic-size slot that can fit weapons even stronger than XL weapons, such as the immensely powerful Perdition Beam that can fire across a whole system and potentially destroy a battleship in a single shot. Titans also have an aura slot that can fit a single offensive or defensive aura that can buff friendly ships in the same fleet or debuff nearby enemy ships. Titans are intended to be the flagships of your fleets, and as such are limited in number: You can always field at least one Titan, plus an additional amount dependent on your overall naval capacity.

Ion Cannons (Apocalypse Feature)
Finally, there is one last Apocalype feature to talk about for today: Ion Cannons. Ion Cannons are stations that can be built as part of the defense platform fleet of a Starbase. Each Ion Cannon is essentially a single massive gun emplacement that mounts a single Titanic weapon, allowing the Starbase to engage enemy fleets at massive ranges and greatly improving the Starbase's ability to deal with enemy Battleships and Titans.

That's all for today! Next week we'll continue talking about Cherryh and Apocalypse expansion, on the topic of Marauders, Pirates and the Great Khan.

Too similar to the robots for my taste.

What about something more asymetrical? Like the Mycon Deep children, where the Behemoth consumes itself (cost balanced), and turns the planet into a living hive-mind, turning all pops into bio-mass cocoons, and offering a specialized structure pallet like a Habitat for them to work?

Or just turns it into a Hive World that produces a flat food/bio/mineral output.

In either scenario, it eventually dies when the connection to the hive mind is severed; reverting to a Barren world in need of terraforming.

I'd like to see Devouring Swarms with biological, living ships and weapons, and greater reliance on food, and their superweapon could turn a planet into a huge food source for them by mutating the life on it and turning it into a huge biomass source.

This would be something unique and also mechanically interesting for them.
 
I would really like some form of "tech destruction", that wipes off all technolgy (buildings and robots) from the planet, but leaves population intact, emilinating threat from the planet

As a variant of this, a "regression weapon", that makes the inhabitants of the planet fall down to pre-industrial (become a primitive nation), or even to pre-sentient. To be potentially uplifted as used as tools at you leisure.

In fealty to the God-Emperor (our undying Lord) and by the Grace of the Golden Throne, I declare Exterminatus upon the Imperial World of Typhon Primaris.

I hereby sign the death warrant of an entire world and consign a million souls to oblivion.

May Imperial Justice account in all balance.

OH! THAT'S SO COOL!

The whole galaxy will learn the divine love of Birdjesus. By Force!
 
I will repeat what I said in the very beginning: I'm only okay with planet destruction if the game also has planet creation.

I've always played Paradox games because I enjoy building up my territory, not destroying other empires. I only engage in war because it's necessary, not because I enjoy it. I will spend decades in CK2 building upgrades, building up tech, and politicking internally without ever declaring a war.

Having someone blow up one of my planets with nothing I can ever do to get it back is not fun to me, and I'm unlikely to blow up any other planets unless it's the only way I can win.

Give us the ability to turn asteroid fields and destroyed planets into regular planets again, and you'll have me hooked. I want to be a constructive force in the galaxy, not a destructive one.

I imagine that if you have the correct ascension perk, you could always construct a ring world in the system of your dead planet, which thematically does use up the asteroids/whatever.
 
I think you should be able to shield your own worlds in order to protrct border worlds from the late game crisis. Like better to seal them up than let them die. You could make it non-permanent in thks case maybe, not sure. But it would be nice for roleplay
 
Depends if you add a "Really vulnerable vent" on the ship loadout.

Maybe every colossus could have a secret weak point that you could research. One might be 'explodes if hit by a single torpedo', another could be that disruptors reset its firing cycle, or maybe it has an AI flaw and a science ship can capture it. None of those work until you complete the special project, of course, which requires you to capture the starbase that built it.
 
A twist on the idea of planet-destroyer for biological hiveminds - the bombed planet goes into incubation period. The player can choose either free food or to spawn a monster-ship. Maybe a battleship class or similar? Could be even a mini-leviathan - something between Battleship and a titan if you will. An incubation period could be pretty long and shortened a small bit with the amount of pops on the planet, something like 24/36 (if battleship-like) and 60/120 (if bigger) months and minus one month per pop. Respectively the planet could be bombed again by opponents to destroy the spawn.

I'd imagine part of the reason you can't unshield worlds that you've Bubbled is because they stop being normal planets. Like, how would you work out a way to make a planet fully functional, but non-interactive and give no resources and no information on the surface? It'd be way easier (and more efficient for coding purposes) to just wipe out the original planet and replace it with a Shielded World with the same name that doesn't actually have any tiles or POPs or buildings, etc.
 
I like the pacifist planet destroyer a lot. It amuses me.

'Hello. We have tried to be reasonable but you have forced our hand. Welcome to 'the corner,' you will be remaining here for quite some time to think about what you have done.'
 
I think I would like to see a way to 'unbubble' a planet. Like it makes sense that Pacifist races would want a way to subdue a planet without hurting anyone, but at the end of the war one should be able to take the handcuffs off and say "you're free to go".

I'm gonna be honest, and I say this as someone who is almost certainly going to buy the DLC, I don't like that the colossus, titan and Ion cannon are paid features. This (to me at least) smells of the harmony system and traditions, where it'll be better off being free and then being built on. For example, I'm sure that in the future there's going to be an expansion that adds different types of ship hulls (hardlight or biological as an example) or new planet destroyer weapons, and you'll need this DLC to gain the full effect of it.

Maybe make it so that the planet cracker is free and the rest are locked behind a paywall?
 
I also want to see this (shielded worlds being freed), but for different reasons, I want a recreation of the events of Star Control 2 with slave shields getting taken down and the fallow slaves rebelling against the Ur-Quan Masters.
 
I like the idea of building a "Death Star" to destroy a planet, but latelly I have to say many of Stellaris' features feel way too "magical" to me, and I feel the game is losing its focus and trying too hard to do everything.

Such as a magical god ray that turns everyone into mummies. Will probably be cool to have ingame, but a bit too... supernatural to my liking.

I like the mummy dispersal ray, though. It will be cool to play the new mummy DLC that lets you spread nanogenes around the planet to reprogram and reshape everyone to something vastly different. This has chilling potential, and it'll be "interesting" to see what will happen if a mummy uses it on a new planet and... sorry, it's hard to see the screen through this gas mask... if the nanobots don't regognise the... the planet's lifeforms and...

...mummy?
Are you my mummy?
Muuuuuumy?

Aw man, you beat me to it. I just HAD to read the entire thread first didn't I? Let me just add to that then.
