Is there a way to put an end to the meteor shower on Earth? And/or putting an end to the flying drones and the submarine drones attacking me? I want to see what it looks like having the colonists settle down back on Earth. But I'm afraid they'll be shrieking their lungs out all day if I was to do that without taking care of the drones and meteors first.
The lab is a temporary area, you don't get to access it again. Right now, I'm focusing on adding multiplayer and releasing the game as it is, not additional post-ending content, but I'll keep your ideas in mind for potential post launch updates. For earth, you cannot end the meteor shower (some players suggested a moon-quest where you could stop it), but they do not harm buildings or tiles, and can be blocked completely by walkways (unlike bombardment, which breaks walkways). Once you deactivate the drones, they will only attack if they are damaged and malfunctioning - if you aren't attacking them, and they aren't being hit by meteors (protected by walkways), then they will be docile.
