i have been working on this world for quite some time, and still am. It is modeled after the planet Reach from Halo, and uses the seed Glacier. right now, it includes:
-a base/outpost
-a hangar with a pelican in it
-around 10 individual pelicans placed around the area
-a huge pit of death (had to add it)
-an underground (bomb shelter, hangar?) whatever you want
-a super secret room...

still planned:
-underground bases in cave systems and such
-at least three more finished outposts
-a training facility
-more secrets
