Hello everyone!

We aren’t quite ready to show the things we are working on currently, but from the beginning of January we’ll be back with more dev diaries to talk about things like the Unity rework or the new Situations system. For now, we’ll be taking a hiatus until January 13th.

We want to instead take this opportunity to celebrate the year that’s gone by and thank you all in the community for your continued support.

Looking back at the year:

Come all you young spacefarers, listen to me! I’ll sing you the song of this dev diary!

Space shanty? Sing-along version? Amazing.

Today we’re back with another dev diary, and today we’ll be talking a little bit about our next steps. But first and foremost I’d like to thank everyone in the community for showing such great appreciation for Aquatics and the 3.2 update. The Aquatics Species Pack is the best-selling species pack to date, and going by the Steam review it also seems like it’s very well-liked. The future is looking bright, and together we will be able to make Stellaris bigger and better than ever before!

Embrace the life of a seafaring civilization with the release of the Aquatics Species Pack on November 22nd for USD $9.99!

Choose to originate on a large Ocean Paradise world, with increased pop happiness, output, and growth. Or choose the Here Be Dragons Origin, and start guarded by a sage-blue - and occasionally very hungry - space dragon, which will protect you from harm, as long as you keep it happy.

Specialize your species with the Aquatics Species Trait, which further optimizes your species for living on Ocean worlds, but penalizes living on Cold and Dry planet types.

Become interstellar seafood harvesters with the Anglers Civic, and harness the bounty of the ocean with fresh seafood and rare pearls as staples of your Empire’s economy.

Hi! My name is Fenni and I’m an Art Producer for Stellaris.

Today, I will talk a bit about our art processes and give you a little behind-the-scenes look at how our amazing team of artists worked when creating the Aquatics species!

Exploring the narrative When creating a new species, we first start by exploring the theme, story and narrative of the species. When creating a character inspired by an existing animal, we also first explore why this animal looks the way it does and what specific characteristics we can identify. How did the animal evolve to look like this? How has the environment it lives in shaped it’s appearance and behaviour? This helps us understand what elements and why something looks and feels the way it does, and we can use it... Read more

Hello! My name is Pavel Golovii, I am a concept artist from the art team that has worked on the Stellaris Aquatics Species Pack. I am going to highlight the process of developing ship designs from a concept artist perspective. I will talk about the initial ideation process, inspiration, visual language and defining the look of individual ship classes.

Brief The work of a concept artist is to suggest a clear visual interpretation of game aspects often based on initially vague ideas and definitions. At this very first stage our goal was to probe for the style for the aquatic ships, invent a sort of a visual language that we then cou... Read more

Hello everyone!

For today’s dev diary we’ll be talking a little bit about a new wave of changes coming in the upcoming 3.2 update.

3.2 will feature some new content and features, some of which didn’t make it into 3.1, and some of which are new. The reason why I mention that is because I also wanted to shed some light on the process itself. With this new way of working, it’s fine if something isn’t done for a certain update, because it can simply spill into the next update. With our ambition of only having 3 months between the updates, it will not be long before the new piece of content will be out in the public. Speaking of which, the new Pompous Purists Civic is just such an example.

Hello and welcome to a new Dev Diary,

My name is Guido and today I’m here in my role as a Principal Designer on Stellaris to talk about AI in a bit more detail.

You probably have heard about the Custodian Initiative by now which has been created to keep improving the game on a more regular basis and in order to be quicker when reacting to player feedback. A part of this initiative is also to put some more love and attention to the AI of the game going forward - an AI initiative inside the Custodians, basically.

For this, we have set some goals for ourselves going forward:
  1. Always work on AI-related topics, regardless of what else is going on
  2. Move the AI towards being challenging to players in an entertaining way, rather than be optimized to min-max its way to v...
