But I can't really help you with custom parameters for your server, not sure what that has to do with the Zeus module

Possibly. I'll look further in depth of Eden because of this

Do you mean:
Systems -> Logic Entities (the flag symbol above the search bar) -> Virtual Entities -> Zeus
?

That's what I already know . For scenario's like this you use starting slot for Zeus like "Game Master" and "Game Moderator", that's what I want to know how to do so I can set custom parameters for my servers

So this is not a question about this Scenario but a general question?
For multiple Zeus you need multiple players (the easiest solution is just multiple units, set to playable) with different (variable-) names assigned to them and multiple game master modules, one for each (variable-) name.
So for example Player One has the variable name "p1" and a Zeus module with the owner set to "p1". The same for Player two and so forth.
You can find a few tutorials on YouTube, maybe that helps too.

No, but I don't blame you for not understanding since what I'm asking is quite hard to word out. What I mean is, how can I make a zeus mp mission with several zeus starting slots? What modules would I have to use in the editor? (like Game Master module etc.)

I'm not sure if I understand your question correct, but this is a multiplayer mission with one slot for Zeus and multiple player slots. The players can not access the Zeus menu and the Zeus player can not participate as a normal unit, since he is the game Master (Zeus).
If you want to play this alone, I would recommend going to multiplayer and opening a local server (LAN) for yourself.

I hope this answers your question

Yo how do you do these setups? I know how to do it so you start as a character then press Y, but how do you make it so it has a starting slot etc.

Thanks a lot

dude you are the best honestly your awesome dude keep up the good work
