Map that used portals in a spaceship setting?

[invictius]

It was part of a community project.  Can't remember which one.

 

Also, so I don't start another thread, trying to think of a community project where you start in a circular room with pics of all the maps in the wad, and jump through to select the one you play.  Included vanilla, boom and zdoom maps.

Doomworld Mega Project 2016 meets your description, except for the space theme.
