There are Jupiter cloud colony concepts.

is it in the jupiter planet?

6

It's 1 mission.

There is a problem with mission icon too in overviews/boarding.txt it can be set to an objective icon, because vgui/outpost7/boarding doesn't exist:
"image" "swarm/objectivepics/airlock"

and with credits file path in outpost7campaign.txt
"CustomCreditsFile" "resource/outpost7credits"

how many levels in this campaign?

Very nice concept WIP map! With a bit of polishing and detailing could be a very good map. I liked the little details like the Among Us poster, air from the broken glass, the dead body floating in space and the visible Jupiter surface below the space station.
One problem with map is that download URL is not shown in game and people can't download it from in-game. To fix this you need to edit overviews/boarding.txt and put

"website" "https://steamcommunity.com/workshop/filedetails/?id=2225112897"

Good job!

I enjoyed your map. Hope to see your next map soon. Well done and thanks.
