Totally Safe Moon Project Achievements Guide (All 44)

Totally Safe Moon Project has 44 Steam achievements: 11 for height goals (10 m up to 425 m), story completion, Chaos Mode, fall damage, UFOs and asteroid rain, plus a long list of silly physics challenges like throwing a car from a great height or attaching a house to a tree. Five are hidden. The rarest as of November 1, 2026 is finishing in Chaos Mode (about 2% of players), and the golden bucket ("Expensive Thing") is found by only about 6%.

Unlock percentages below come from Steam's global achievement stats on November 1, 2026, a few days after launch, so they will shift as more people play.

Quick plan for 100%

1. First run (normal): play through the walkthrough with the Fall Damage setting on. That gets you National Heroes and Not Afraid together, all eleven height goals and most of the object challenges along the way.
2. Clean-up while you build: carry a tree past 100 m, an NPC past 200 m, throw a car from high up, attach a house to a tree and an NPC to a bench, glide with the umbrella for 30 seconds, and lift a windmill once your Gravity Gun is strong enough.
3. Co-op only: grab a friend with the gun (I'm the Boss!) and throw one off above 125 m (This Is Sparta!).
4. Second run: finish in Chaos Mode for "Difficulty? I'd like a little more". See how long to beat.
5. Idle ones last: leave the game running AFK for 5 and 30 minutes.

Notes on the hidden achievements

Steam hides five achievements until you earn them: Clear Sky (take down a satellite), Christmas Tree (attach an NPC to a tree), I'm Your Biggest Fan (pick up a windmill, the heaviest object in the game), Basketball (score a basket), and I'm Smarter, I'm Better. Most of them reward messing around with physics. "I'm Smarter, I'm Better" is unusual: it is awarded when you "try to exploit the game by repeatedly building with the same few objects (and get caught)", which tells you the game watches for players reusing the same pieces.

Golden bucket (Expensive Thing)

Only about 6% of players have found the golden bucket. A player replying in the Steam discussion "where" said it is not inside the city but outside in the mountain area. We have not yet verified the exact spot with a second source, so treat that as a lead rather than a confirmed location. We will update this section once it is confirmed.

Fall damage and Chaos Mode

Not Afraid requires the Fall Damage setting to be enabled for the whole run, which means falls can knock you out and you will need teammates to revive you (hold E) or wait to respawn. "Difficulty? I'd like a little more" requires finishing in Chaos Mode, which one Steam reviewer describes as adding "side-quests" to the climb. More in our upgrades and tools guide and UFOs and asteroid rain guide.
