Story & Ending

Moon Sweepers does not take itself seriously, and its story is a running joke about corporate cost-cutting. Here is the setup, the world, and — clearly marked — the ending.

The premise

Someone discovered that the moon is covered in dust, and decided this was unacceptable. The Lunar Surface Division — LSD on your paperwork — was founded with a single mission: clean the entire surface of the moon, on a budget of almost nothing. For reasons nobody explains, you applied.

Signing on. The contract makes it very clear how much the Division values you.

Your contract

Your application was accepted because it was the cheapest. Your title is junior surface hygiene associate, disposable grade. The contract states that your shift ends when the moon is clean, and you sign it with a free-hand signature box — draw whatever you like. Then you are told to collect your equipment from the supply wall: a toothbrush.

Everything after that is played straight-faced. The Division sells you better brushes, the upgrade terminal treats a 6% raise on dust contracts like a career milestone, and the most expensive robot in the catalogue is named, with complete honesty, Just One Overpriced, Non-essential Automated Sweeper.

The world

The moon is a full sphere of 163,841 hex sectors, with mountains, craters, long nights and Earth hanging in the sky.
Stations — twelve of them — are the Division's outposts, each with a depot, upgrade terminal, moon map and a break room with chess, air hockey and coffee.
History is everywhere: 26 survey sites recreate real landers and crash sites, from Luna 2 and Apollo to modern commercial landers.
Flags — one for every country, all tangled — are waiting to be straightened.
Where does the dust go? It is packed into containers and launched into space. Who buys it is never explained.

The ending (spoilers)

Spoiler

Stop here if you want to see it yourself. It is worth seeing with the sound on.

When the very last hex is cleaned, the game plays a short cutscene. The moon — now spotless and reflective — turns out to have had a very good reason for its dusty coat. The result is catastrophic for the planet hanging in your sky, and afterwards you can look up and see Earth in pieces. Your shift is technically over. The Division's main channel would like a word.

After 100%. A clean moon, and a rather different view of home.

You can keep playing after the ending to finish flags, sites and achievements.
