Stellaris Dev Diary #293 - Introducing Coop

Hello everyone!

One of the major Custodian features planned for the 3.8 ‘Gemini’ update is the addition of two cooperative gameplay modes. Up to five players will be able to control the same empire and work together to play the game as a team.

Two Modes of Play​

Surveys suggested that there are two distinctly different reasons people want to play together.

  • I want to play a PvE game of Stellaris with my friends, either to teach them how to play the game or to have a more relaxed game where we can share the duties of empire management.

Stellaris is a complex game, and learning to play can be difficult without a guiding hand. While some people learn well by watching informative videos created by the community, others might do better playing alongside a friend.

  • I want to play a multiplayer PvP game of Stellaris where teams of players go up against each other.

The cognitive load when playing competitive multiplayer can be at times overwhelming, especially during wars. Being able to split duties with other players on the same team could provide an enjoyable experience.

We’ve tried to support both goals through two different modes of play, with slightly different game rules.

Cooperative PvE​

A new main menu entry exists for starting a Cooperative PvE game where all human players control the same empire.

Main Menu Bar now includes Cooperative mode

This will bring them to the Game Browser screen, where one of them can choose to Host a New Game, just like the regular Multiplayer flow.

The hosting player will go directly to Empire Selection, where they can create a new empire or select one they’ve already created as normal, select the Galaxy Settings for the game, and then begin the session.

Unlike regular Multiplayer, the Cooperative PvE flow bypasses the Game Lobby, and the coop players will not need to select an empire. These players hotjoin directly into the hosting player’s empire once the game has begun.

For most purposes, Cooperative PvE is treated the same way as single player PvE is.

Competitive PvP​

The flow for creating a competitive multiplayer coop game is similar to the normal multiplayer flow. One player will host the server, ticking the “Allow Coop” checkbox.

Other players can join the Game Lobby and open their empires up for additional players.

Empires that have been opened for cooperative play add an “inspect” icon to the portrait so prospective players can see the details on the empire before deciding to join.

For more competitive players, the primary player of the empire will be able to lock their empire, which will add a password requirement to joining or inspection.

New Coop Features​

It’s often useful to know what your teammates are up to. To make it a little easier to understand what’s going on, we’ve added Presence Markers to the UI to show which tabs your teammates are currently using.

Presence Markers and the Goto buttons

pdx_eladrin is currently taking care of our research issues, so Loner can worry about something else.

We're currently exploring the addition of Goto buttons in the top right corner that will allow you to bring your camera to your teammate’s location, but this isn't fully functional yet. (And is unlikely to be during the Open Beta.)

Events will be shown to all members of a coop team, and any of the players can select a response. The window will remain in place with the selected option marked with the icon of the player that made a choice.

Event with an already selected response

Only one option for this one, but it’s nice to know it’s already been selected.

What’s Next?​

Next week we’ll be talking about the 3.8 ‘Gemini’ Open Beta.

As the Coop game modes touch a lot of moving parts, we’d like to gain feedback on your thoughts of how it plays as well as find where desyncs and other bugs crop up before the actual release.

This might reinvigorate, or further boost, the stellaris streamerscene. Imagine having your Patreons commanding fleets, ruling sectors or governing vassals. Create a community that democratically debate matters in the stream, seeing their chosen policies enacted. Awesome.

Not my thing at all, but I do look forward to the stories of how one 'friend' sabotaged our last game by maxing out negative traits on several dozen genetic monstrosities for sh*** n giggles. Or decided he was the spymaster for your worst enemy because they were bored being the poor sclub having to change job priorities.

Co-op will be the somethingsomething that will just keep on giving.

Wow! This news made me log back into my account for the first time in over a year to let you developers know that you are incredible, again. I didn’t even know I wanted this feature, probably because I never would’ve even considered it to be a possibility. This is exactly what this game needs on so many levels, I can’t wait to try this with my friends and see how it goes. I really hope the next DLC is going to be an internal politics expansion that allows us to have some mechanics to aid in our role-playing of running a single empire. Maybe with some sort of mechanic that allows us to split later on . Wow, this is going to add like 1 million hours to the games life.

First things first, will we be able to designate sectors of the empire to specific players? So if you had three players, each could only colonize/build/recruit in their designated sectors?

And now for the repetitive part:
1. Base template for Fallen Empires' slaves, so we can remove the nerve-stapling without the Genetic Ascension perk
2. Nuclear War should be an event chain, instead of the RNG just going "Oop, everyone's dead now" without warning. At least some warning of rising tensions. Really, almost anything would be better.

Honestly, this doesn't sound like a bad idea. I've been trying to get some of my friends into the game, though grand strategies and careful management of resources isn't their forte. This would be very useful in teaching them specific areas of the game.

Or for that friend that we all have that is always terrible at economies and just wants to wage war all the time. We all have that friend.

With this change, can we PLEASE get better pause functionality in multiplayer? I get why you don't want pausing to be annoying or abusable in MP, but even back in 2.1 when I started playing, it was so frustrating how neither auto-pause nor Spacebar-to-pause work in multiplayer even when 100% of the human players want them to! Co-op games - no weird hacks or anything, just old fashioned comp-stomps - have always been a thing in strategy games, and Stellaris is the only such game I know of which requires so much reading and decision-making (especially for a new player who doesn't know the events and value of rewards by heart!) yet all-but-forces it to be done in real-time for multiplayer.

So, again, PLEASE let us use auto-pause and spacebar in MP, not just in the new cooperative games but also as an option in all multiplayer!

Well, if the Gemini patch main focus is the coop, wake me up when the next patch/DLC DDs start droping.

Friendships will be broken. Divorce papers will be submitted to solicitors.

And it will be all v3.8's fault. :D

Coop is a great addition. This is lots of fun in HOI. Related to this, I was hoping for a way to setup a game that would allow players to start as a vassal of another player. Also, allowing teammates to switch between the various vassal entities would be neat.
 
I would really like a way to "assign" players and "lock" them into certain tasks/roles/actions during coop. For example I'd love to give control of a fleet or a single colony to one of my friends and prevent the others from touching it for when I use Aristocratic Elite/Feudal Society. My head canon is that the nobility acts independently and only the player assigned to the Ruler is able to ignore these locks.

That actually would be amazing. Basically players become governors :)
Exactly what I was thinking! It could also make vassalage more interesting, where accepting annexation would allow you to govern your sector of the empire with greater benefits.
