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.

Seems to completely bypass ground combat once achieved. Since I like ground combat, I think I'm going to want a mod that gets rid of planet destroyers. This shouldn't be taken as criticism, I can see most would like this. I'll have to see what else is in Apocalypse. It might be the first paid expansion for Stellaris I skip.
 
Not every type of empire gets its own planet destroyer, though we may very well add more later. What weapon would you suggest for Hive Minds (besides the basic ones they already have access to)?

I can't believe you have trouble imaging one....

Basically swarm of trillions army descending to consume the entire planet and turn it into a hive mind world.

Something like Leviathan Fleet from Warhammer 40k comes to mind.

That sounds more like a regular invasion than a super weapon.
 
I'm really happy to see this - not the least of which is the ability of star-bases to have titan class weapons. I'm looking forward to being able to really consolidate a star system and feel like its defended when my doom stack isn't around.

Some kind of naninte beam that alters the neural structures of the single minders and adds them to the Mind. Basically the same as the assimilators but a different effect. Maybe only usable after the biological ascension in the case of the hivemind.

The thing is. There is already a different "regular invasion". Called Nanobot dispersal which turn all of the population into assimilated population.

That's exactly how conquering a planet works, though.

The idea that turns it into a gooey processed food source makes more sense. For devouring swarm at least. Otherwise, they can just use neutron sweep.

Maaaaaybe if you're not a devouring swarm, and have biological ascension, a nanovirus distributor that mods the pop into hive mind and makes them defect (like the assimilator weapon) makes sense, without actually changing what species they are.

Edit: 2 different people made these 2 points in 2 posts before I did :p

Can't honestly see them having access to a planet destroyer but a Hive Mind having some kind of ship that unleashes swarms down below to consume all life Tyranid style would be pretty epic.

Yes but we're talking about something being done from orbit, not after an invasion.

Calling nanoplague an invasion is like calling anthrax bombing an offensive.
 
Empires that can't purge won't be able to build or use purging superweapons right? (of course, anyone could still build the world pacifier, so superweapons won't be banned entirely)

Also, will Apocalypse be a major (Utopia sized) expansion or a smaller story pack?

Riiight... An invasion happens from orbit though.

The suggestion was a superweapon that drops answarm of armies onto a planet and turns it into a hive world. This is exactly how a devouring swarm conquers a planet, except accelerated.

The driven assimilator weapon isn't an invasion, it's a nanite swarm. Like a virus. I agree, in effect it's identical to taking a planet and assimilating the population, but it's different in flavor.

Flavor does matter. Which is why I'd be for a non-devouring-swarm hive mind with biological ascension having a superweapon option that does the same thing. A nanovirus spray or whatever.

A superweapon that just does the same thing as 100 transport ships, but faster, is just seems unnecessary.
 
Would be nice to see at least one titan variant for at least the middle and rear slots, for roleplay reasons. In the late game when you have a couple titans, it would be sort of lame if they all looked and worked exactly the same. You'd think if they require so many resources and (presumably) so many engineers working on them, later titan designs could be substantially different. Compare, for instance, some of the major design differences between the Nimitz-class aircraft carriers. A middle section with two or three XL slots would be neat.

As for a potential hive mind colossus, I'd imagine it being a "Queen ship" able to overrun planets and immediately conquer them without first taking down the starbase/outpost. I don't think that would work in a gameplay sense with the current starbase system, however, so that idea is probably moot.

I believe that the Hiveminds fall into three categories:
1: Synthetic Hivemind - Already covered by Assimilator Superweapon. (Already given lots of love by Paradox)
2: Base/Psy(?) Hivemind - We don't need a special superweapon
3: Bio Hivemind - This is the one that gets the most love by the community, Here I would suggest a weapon that, unlike the synths' assimilation, makes the world an "Infested world for 6 months that yields 25-100 food (Based on the number of pops), and just hands those resources to the owner of the superweapon. after the 6 months, give a base 100 food (scale for gameplay), a boost to ship production/regeneration, pop growth, and biology research.

The idea is that if someone is playing the "Organic Hivemind" approach, most are already using the Prethoryan shipset via mods, (I would suggest making this a base shipset, along with the AI shipset) play to this by making this organic superweapon boost the ships, and empire the way one would expect. Play to the approach of WH40k's Tyranids, or Halo's Flood, The goal with most of the comments by people, is to draw attention to the fact the community is so eager to have this playstyle open.
 
Calling nanoplague an invasion is like calling anthrax bombing an offensive.

Nanobot* is indeed an invasion which result in a "quicker" assimilation than a regular invasion where you would have to dealt with normal non-assimalited population.

So how are you getting off at calling nanobot dispersal a "non-invasion" which let you skip a normal invasion?
