Here is my 100% Guide for Deliver Us The Moon!
This is in chapter 3 (Copernicus Moonhub) and its for fixing a little robot buddy.
You have to find the pieces first.
So once you place it on the table, Piece 1 is directly infront of you on the same table.
Piece 2, is to the right of where you are on a desk.
Piece 3, is then to the left of where your robot bud is, in a little room.
Return to the robot and fix him up.
It is an easy puzzle to complete.
Once that is finished, the room in the back will open up as you will be able to see.
Go into that room, and on the right hand side of the room, top corner there are another bunch of components to pick up.
Grab them, return to the robot, fix him up with another small puzzle and he will become alive!
Therefore unlocking the achievement!
