OPUS Prism Peak Achievements Guide
OPUS Prism Peak has 42 achievements, and most of them tie directly into exploration, photography, and how thoroughly you interact with the world. Some unlock naturally through story progress, while others require very specific actions in a single playthrough.
All Achievements in OPUS Prism Peak Explained
OPUS Prism Peak achievements are earned through story progression, taking photos, collecting hidden items, and completing Field Notes objectives, with many requiring full completion in a single playthrough.
The game splits achievements into a few clear categories, and once you understand that structure, it becomes much easier to plan a full completion run.
Story Progression Achievements
These unlock automatically as you move through the game.
A Fire Dims
The Dusklands
The Road
The Forest
The Nightwaters
The Summit
Ending achievements also fall into this category:
Home
Farewell Itself
Reaching the True Ending requires more thorough completion compared to the Normal Ending.
Photography Achievements
These are tied to how often you use the camera.
Amateur Photographer, take 30 photos
Apprentice Photographer, take 100 photos
Professional Photographer, take 250 photos
Master Photographer, take 400 photos
Specific photography achievements:
OPUS: The Day We Found Earth
OPUS: Rocket of Whispers
OPUS: Echo of Starsong
These require photographing specific objects like ads or posters found in certain locations.
The easiest way to handle these is to take photos constantly during exploration instead of trying to grind them later.
Collection Achievements
These are the main completion-focused goals.
Glimpses
Wishes
Memories
Passage
Not Forgotten
Gearhead
Most of these require finding every collectible in the game, and several must be completed in a single playthrough.
This is where most runs fail. Missing even one item means starting over for that category.
Field Notes and Research Achievements
These are the most demanding achievements.
Language of Fire
The Old Stories
Full View
Research Notes
Spirits of the Dusklands
Really See Them
These require full completion of Field Notes systems, including decoding runes, restoring notes, and fully observing spirits.
They are tightly connected, so working on them together in one run is much more efficient.
Challenge and Condition Achievements
These require specific playstyle conditions.
Who Needs Cleaning, never clean the lens
Untouchable, never get rescued
EV+6
EV-6
Not a Speck Wasted
Not a Speck Spared
These are easy to miss and often conflict with each other, which means multiple runs are usually required.
Exploration and Interaction Achievements
These reward thorough exploration.
OPUS4, talk to every spirit
The Stars, sit at the Great Flow
Full Circle, inspect all statues
I Know the Sacred Lake
I Know the Nightwaters
These depend on visiting specific locations and interacting with everything available.
Best Strategy for 100 Percent Completion
Trying to get everything in one run is not realistic.
A more efficient approach looks like this:
first run for story, photography, and general collectibles
second run for strict conditions like no cleaning or no rescue
dedicated run for full Field Notes completion
Many achievements require “single playthrough” completion, so planning ahead is important before starting those runs.
Final Blurb
OPUS Prism Peak achievements revolve around how deeply you engage with the world. Story progression gives you a solid base, but full completion depends on careful exploration, consistent photography, and planning for single-playthrough challenges. Once you understand how each category connects, finishing the achievement list becomes much more manageable.
