Outer Wilds — Achievement Walkthrough

Sprint off the cliff outside the campsite at the start of a loop. Fall to your death within 60 seconds. Or run into the geyser. Or jump into the village fire. Many fast-death options.

Loop restarts; achievement persists.

Your suit has limited oxygen (10 minutes). The achievement pops when you do something risky — like using your oxygen to thrust-jet in zero-G in a way you weren't supposed to.

Experiment with the suit thruster mechanic.

## What's needed
The Travelers (NPCs across the solar system) each play unique instruments. Find them all alive in the same loop, signal-scope locked to their tunes.

## Strategy
- Memorise each Traveler's location and time-of-loop position
- Use the signalscope to confirm their tune is being received
- Travel between planets quickly; pick up all 5 signals before time runs out

Late-game achievement. Hidden until late.

On Brittle Hollow, find the gravity cannon (large alien tech). Land your ship inside, activate the launch sequence. The ship is fired across space — exhilarating.

The achievement is named for the sound. Story moment with consequences for what you do post-launch.

The cartographer probe is high in Giant's Deep's atmosphere, accessible only by riding a cyclone upward. Find a cyclone heading up (not all do), ride it precisely. Land on the probe to silence it.

Sit near a campfire (Timber Hearth, or any other planet's fires). Stand in the smoke trail. After enough exposure, the achievement pops. Small joke about the in-game smoke effects.

Your suit has buttons that should NOT be pressed mid-vacuum. Press one anyway. Consequences ensue. Game has a sense of humour about your curiosity.

Outer Wilds is a 22-minute time loop. You will die many times — first death pops this. The reference is Majora's Mask. Don't try to avoid it; embrace the loop.

Stuck or wedged in geometry. The Unity physics engine occasionally clips. The achievement pops on memorable physics-glitch moments — usually involves cliff edges or zero-G tumbling.

Find the model rocket toy in Timber Hearth village. Launch it toward Attlerock. Requires precise aim — adjust angle and power. Bring up the moon's position before launching.

Jump from a very high cliff or out of your ship while in high atmosphere. Hit the ground hard. Achievement on the painful landing.

Most players unlock this naturally. If not, climb the highest peak on Timber Hearth and jump.

Fly far enough from the solar system that you're 'outside.' The loop continues regardless. Achievement on the failed escape attempt — appreciate the design choice.

Mica is on Timber Hearth, near the observatory area. She has specific dialogue branches that lead to her getting frustrated with you. Pick the obstinate options.

In the museum on Timber Hearth, the flight simulator lets you practice. Fly through all the rings without crashing into terrain. Pop on perfect completion.

Gently steer; the ship has slow rotational momentum.

Certain items in the game CAN be carried back to Timber Hearth's museum. Find one, hold it during launch, drop it at the museum's open exhibit. Achievement pops on placement.

Fun bit of agency — the game lets you preserve artefacts.

Aim ship at planet, full throttle, smash. Crash damage usually wakes you. Easy if you're not careful with thrust; intentional if you're going for it.

Specific late-game discovery typically locked behind knowledge gates. Pop if you happen to reach it without the gating clues — luck + experimentation.

Most players get this on a replay where they know the route.

## The challenge
Heal yourself enough times that cumulative damage exceeds your max HP, but make it to the loop's natural end (the sun expanding) without dying.

## How to take damage safely
- Touch ghost-matter (it damages slowly)
- Take fall damage repeatedly
- Use the medkit between hits to heal

Needs careful planning; expect multiple attempts.

## The ship log
Tracks every clue, artefact, and location you've discovered. Entries marked with '?' need more investigation.

## How to complete
- Visit every planet, fully explore every nook
- Read every Nomai writing (use the Translator tool)
- Find every Traveler
- Visit late-game locations only accessible with specific knowledge

Wiki has the complete ship-log entry list. The hardest entries require specific time-of-loop windows on specific planets.

Get high enough in orbit to clearly see Timber Hearth as a curved planet. The achievement is a flat-earth joke — disprove the conspiracy by direct observation.

Various locations have grates too small for your ship. Exit your ship, jet through. The achievement pops on a specific grate (likely the Ember Twin or Brittle Hollow inner-core entries).

Launch your scout probe toward the sun. The scout takes a photo before it incinerates. The image arrives at your scope. Sun close-up photo = achievement.

Endgame area. Reaching the Eye requires the Advanced Warp Core + the Vessel + multiple late-game discoveries. Achievement pops at a specific revelation within the Eye sequence.

Unambiguously a spoiler — won't say more.

The temperature in the name is Fahrenheit 451 converted — Bradbury reference. Burn an in-game readable artifact. Light it on fire at a campfire or burn it in a hazardous environment.

Some puzzles have multiple valid solution paths. The achievement triggers if you happen to pick the optimal route on a first attempt. Replay-friendly — don't sweat it; comes naturally over time.

Near the end of a loop (when the sun starts pulsing), eject from your ship by pressing the eject button. Or jetpack into space. Final defiant moment.

The ship explodes when the sun goes supernova; ejecting first is the captain-style farewell.

Late in the game, you unlock a meditation ability that fast-forwards to the supernova. Use it once. Reflective — but useful when you want to reset the loop early.

Hidden joke — the '900' refers to an inside joke about the development. Find one specific item (a small alien marble, a Hearthian banner, or similar) tucked in an obscure spot.

Follow a wiki for the exact location; impossible to find blind.

Giant's Deep is the watery green planet. Fly your ship low in orbit and complete a full revolution within 90 seconds. Skim close to the cyclones — they're danger zones but also navigation landmarks.

Dark Bramble is a hostile fog-zone planet. Anglerfish lurk in the fog, killing you on sight. Move SILENTLY — they can't see, but they hear engine noise. Coast on inertia, no thrusters.

For the achievement, you need to actually see one — but don't get eaten. Hide behind seedpods or thrust evasively if spotted.

The Hourglass Twins exchange sand between them via spiral towers. The sand currents are surfable — jump in, ride along. The achievement pops on first successful sand-current traversal.
