I designed and built this portal mission for Empyrion myself:
- write a storyboard
- I made up puzzles
- I made up traps
- design an build the buildings
- place it on the planet
I also redesigned the planet itself to match the mission:
- change the rotation of the planet, so the POI is always on the night side
- make the night really dark
- add some rain
For this Mission I made a Portal, so it became an instance, that can be played multiple times.
