Stellaris Dev Diary #349 - A Storm is Brewing: Announcing Cosmic Storms

A phenomenon is sweeping across the galaxy.​

STELLARIS_Logo_CosmicStorms_Shadow.png


I’m excited to announce that Episode 2 of Stellaris: Season 08, the Cosmic Storms mechanical expansion, will be released alongside the Stellaris 3.13 ‘Vela’ update on September 10th, 2024.


Note: Tooltips shown in the video were from a development branch that has already been updated, more info next week.

Dark Clouds Gather ...​


For some time we have been unsatisfied with the Space Storm that currently exists in Stellaris. Cosmic Storms gave us the opportunity to revamp the system entirely, providing a deeper experience with strategically meaningful gameplay and beautiful upgraded visuals.

With this expansion, eight new storms with varying positive and negative effects are set to spiral across the galaxy.

We’ve also added a new weather map mode for forecasting these storms and predicting their motion, with technologies and buildings to attract, repel, or with an Ascension Perk, even create storms.

... But Every Cloud Has a Silver Lining​


Storms may pass through your planets with intriguing effects, leaving behind a changed landscape or unearthing long buried treasures.

"Burn Fast and Die Radically - That's Always Been Our Way"​


What's life without the rush?

Other empires may obsess about heinous things like economy and population. The Storm Chasers have long since mastered the challenges of their homeworld. The time has come to blast off screaming into the void.

At last, a whole new opportunity to shred the limits of experience!

Embrace the Storms​


Prepare your empires to weather the cosmic tempests with three new Civics, each offering unique strategies to harness the power of the elements.

The Corporate, Hive Mind, or Machine Intelligence versions of these Civics require access to their Authorities - MegaCorp, Utopia, and either Synthetic Dawn or The Machine Age, respectively.

Uncover the Past​


Embark on a journey through the annals of time with two new Precursor Event Chains, each offering a glimpse into the ancient history of the Stellaris universe. These chains weave tales of civilizations long lost to the cosmic winds, with untold secrets buried beneath the stars.

Speaking about storms, will empires that foolishly make a pact with a certain Shroud entity have their former systems shrouded by an eternal storm created by and as a testament to their hubris?

Looks really cool!

Just to clarify, the two new precursor events are actual fully fledged precursors to uncover the same way we would the baol or yuht etc rather than standalone situations or event chains or whatnot?

They're precursors like the others, with relics.

if storms last 80 years, can multiple storms be in effect at once? Does 80 years seem excessive to anyone but me?

I used dev commands to spawn that one because I wanted a tooltip as quickly as possible.

Are games still limited to one precursor chain or is there any plan to make that into a game setting slider or choice like with crises perhaps?

The Zroni Stormcaster creates a generic storm. Does this mean that it will create one of the new specialized storms or still keep it's existing storm effect?

Reactions:
The current space storms have a major strategic impact on warfare that can often allow for tipping the scales by either catching an enemy with their shields down while you are not using shields, or using shields yourself and fighting in a non-storm system against a human opponent who configured their fleets for armor damage only.

I hope the new storms won't be so small and localized that this factor is basically eliminated. That's how it looks so far though. If the storms only affect a dozen systems or so, cases where you change your ship designs for a strategic advantage will probably be rare.

It would be nice if the current galaxy-wide storm remained as a possible occurrence. With the new galaxy map visuals for the storms, the annoying aspect of it - having to check each system - is eliminated.

Whoa Planetscapers, seems we are getting a civic that starts with terraformation tech!! If so, we'll finally have actually useful basic terraformation at the right moment which is early game. Would pair well with Natural Design.

The first non dev comment is a 40K reference.
I can't do this anymore.
It is everywhere.
That seems like a bit of "we see what we want to see". The End of the Cycle isn't WH40K

Do the new precursors use the original "find 6 relics" system, or the newer "fight for the sites" system?
