A long time ago (1.12) I downloaded a space exploration survival map but I can't find it anymore. I want to play it again now that I'm not as bad at Minecraft.
The map was in vanilla 1.12
It included custom mobs and bosses and terrain and stuff
(My memory is a bit fuzzy so the story may or may not be exactly as described)
You start in a giant spaceship with resources and then you get into another smaller spaceship and then stuff happens and you end up in a planet and have to survive and fix your ship before the rescue spaceship goes too far to be able to help you.
If you can include screenshots it would be greatly appreciated.
