OPUS: Prism Peak is a narrative adventure game with photography in a spirit realm. Developed by SIGONO INC. and published by SHUEISHA GAMES, OPUS: Prism Peak was released on April 16th, 2026. Players play as Eugene, a weary 40 year old ex-photojournalist who’s had a rough go of things. While driving to his grandpa’s funeral—the same man who taught him photography—he crashes into a strange statue and is transported to a different world. He runs into a kid—later named Ren—who seems to have lost her memory. Suddenly, a large black and red creature called Shade chases them further into the spirit realm. After getting a camera from a deer, the two venture off, heading towards the mountain peak. It’s a bit of an odd set up, but trust me, it sounds stranger in writing than it does in game.
Players will need to explore each area, taking photos of objects and helping many spirits along the way. Though not necessarily required, much of the game involves exploring the lore of the world and the spirits that live within. The idea of being able to fully see someone, not just physically but emotionally and spiritually, is repeated like a mantra throughout. Players can work towards filling out the many pages in the field journal. Through photography, conversations and a little bit of trust in each other, Eugene and Ren’s story is heartful and emotional. The writers really took the time to nail an impactful story for players that made me want to explore. Sure, players could just zoom straight towards the objectives as they are usually made obvious. However, the game and its narrative encourages you to take your time and explore.
OPUS: Prism Peak is rich with narrative and discovery. My review contains light spoilers, but nothing that’s completely ground-breaking. Most screengrabs are from early on as well. However, as usual, I don’t blame you if you’d like to go in as spoiler-free as possible. The TLDR of it is that this one is pretty good and highly recommendable. The story is heartfelt and well-written. The anime graphics are beautifully done both in characters and setting. Even the gameplay elements are quite enjoyable, snapping pictures and filling out the field journal. In fact, there isn’t much for me to consider a ‘real’ negative. The only things I found were of a personal preference. I gladly recommend picking this one up or at the very least, checking out its steam page and its currently very positive reviews. So, get your Prisma cameras ready, because it’s time to discuss OPUS: Prism Peak!
Eugene & Ren
As mentioned, Eugene and Ren are the main two characters travelling through the spirit realm known as the Dusklands. The deer that gifts Eugene the Prisma camera asks him to take a photo to see if Eugene can really look. However, when Ren tries to get in the picture too, she doesn’t show up. This is not because she is a vampire (though this was my first thought), but instead because she is a “Walker”.
A “Walker” is someone who is fading, carrying the scent of Shade with them—a scent of dark and loneliness. This also explains why she does not remember anything. In order to fix this, we later learn that we need to bring her back home as well as meeting the Seer. The Seer’s story is continuous throughout the game, as most spirits are in some way connected to them. A giant ox is mad at the Seer for leaving and wants him to go back home. A dog feels abandoned by the Seer at the train station. Apparently, the Seer is able to take a good look at spirits, healing them if they’re disappearing. The main goal then becomes to find the Seer in order to heal Ren.
I particularly liked Eugene as a character. As mentioned, his past hasn’t been kind—leaving him with a steady deadpan for most of the journey. In many dialogues, players can choose one of two options to respond to play Eugene as they would like. Maybe you’ll take a more hopeful/helpful route choosing the more positive option. Maybe you think this guy deserves to be a bit bitter and want to see how a more negative route will go. I believe this game has multiple endings and obviously how you play Eugene, interacting with Ren and the spirits, is important. I also enjoy that outside of cutscenes, Eugene typically has a frown and unimpressed look. Though I usually prefer a more animated character when playing in 3rd person, I thought it lead to quite a few funny moments. Eugene seems not impressed at all that he stumbled into a spirit realm.
I also want to take a brief moment to mention again how beautiful the graphics and anime style are in this game. The spirits take on animal forms and it was nice to see how they come to life and get personified in each area. The different areas you play through have interesting settings that make me want to explore, almost wishing the game was open-world but understanding why it is not. When the game shifts away from its usual calm, such as during the Shade’s encounters with Eugene and Ren, the tone never becomes outright frightening, yet it still builds a tense, subtly spooky atmosphere. I think the developers did an amazing job at making this game simply look good and for a game about photography, it probably should.
Photography, Firebowls, & the Field Journal
Speaking of photography, let’s discuss the actual gameplay mechanics. There’s a decent bit going on simultaneously so I may not cover them all. Instead, I’ll focus on some of the bigger mechanics.
In each area, there will be lots of objects to interact with. Interacting with them directly will tell you a bit more about it and reward you with a seed, one of the game’s ‘currency’. It is beneficial if you snap a picture of the object as well. Both of these come into play at Firebowls. These magical bowls appear in most areas. Eugene can ask these bowls a question and a riddle will appear in the flames. If players show the fire the correct photo, it gives you an item—usually something you need to progress the story.
There are also “side riddles” you can solve by watching the fire with different totem animals—the same ones represented by the spirits you meet. The answer to these riddles will be one or more of the various objects you can interact with. The game gives players essentially unlimited chances to offer photos to the fire, and it rewards you with ash each time—even when the picture is wrong. Ash serves as the game’s second currency, which you can spend in the field journal to solve certain puzzles. I’ll get into that more shortly. The rewards for solving these side puzzles include spirit-specific ash and various spirit-backpacks for Ren to wear (like the ox one in the image earlier). Solving these “side riddles” isn’t required to progress, but they do give you a clearer picture of the story—and they’re genuinely fun to complete.
Another thing you can do at Firebowls is drop some seeds to receive upgrades for your camera. This includes objects like lens wipes to clean your camera or more storage. I’m not entirely sure how necessary these are to progress, but its probably better to purchase them anyways. Most objects need just one or two seeds, though the game makes you place each seed individually. This did lead to a slight initial confusion at first for me. For example, the extra storage seems to require two seeds instead of just one like the lens wipes. After getting the storage though, I wasn’t sure if I would keep getting extra storage or if I would get lens wipes again. I think a more standard shop approach would have been easier, but this is just a personal preference.
Filling out the field journal is where you’ll piece together most of the story. There’s multiple pages to fill out and a few different styles of mystery. Pretty much everything you do in the field journal requires a small amount of ash. Many spirits have their own page with their story as you discover it. At times, players will need to complete the story by choosing the correct word or phrase. It is important to actually listen to what the spirits say when conversing with them in order to select the correct one. It is no problem if you don’t choose the right one as you are able to try again at the cost of the ash of course. A similar thing can occasionally be done in the ‘Me’ section which tells Eugene’s story as you progress.
Scattered throughout the areas are murals. These murals tell an overarching history of the Seer and the spirit realm. To uncover more of the narrative, you must match each mural photo with the sentence it belongs to. This I found to be somewhat tricky as not every mural will so obviously line up with one of the sentences. In fact, I think I placed a photo in at least five different spaces before guessing the correct one. Another small gripe I have though is that the photo stayed in each incorrect area. I wish it wouldn’t stick or there was a way to remove them, but again, a personal preference.
The last major mystery and my personal favorite is decoding the language. Many words, most commonly the names of the spirits, are in strange symbols. One section of the field journal focuses on decoding, where you align the correct symbol with the alphabet and the numbers 1–9. Scattered throughout the spirit realm are stones that tell you a few of the alignments. Stones aren’t always easily discoverable though so its important to keep your eyes open for them. It probably isn’t the most exciting of puzzles, but as a fan of linguistics and languages, its something I particularly enjoy.
Solving these things in the field journal are again, not required to progress in the story. However, by solving them, you will have a better understanding of the spirits and the realm they live in. I would imagine that solving everything leads to the best ending. The game knows you won’t catch everything, and it embraces that uncertainty. It gives you two ways to play: with Comfort Mode on or off. Disable it, and the game lets you wander without guidance, fully aware that you might overlook a few discoveries. Turning comfort mode on assists in capturing important photos. It is up to you as the player to decide how you’d like to play.
The last thing I’d like to mention is that the game relies solely on autosaves. Once you progress the story, usually leading to a different area, you are not able to go back. I wish players could manual save or select the chapter/area on the home screen. I’m the type of player that wants to see everything and tries to fully explore an area before progressing. Though the game does usually make the way to progress obvious, it might not be obvious for everyone. There is no indicator that pops up saying something along the lines of “Doing this will progress the story. Are you sure you want to move from this area?” Even outside of this, if I felt like I chose dialogue option in the story progressing part, I’d like to go back and change my selection. Regardless, a small negative (for me) among a sea of positives.
OPUS: Prism Peak, Perhaps the Peak of the OPUS Games
OPUS: Prism Peak isn’t SIGONO INC.’s first game—it’s their fourth. The studio released earlier OPUS titles in 2016, 2018, and 2021. I haven’t played those entries myself, but from what I’ve gathered, each game stands on its own and doesn’t require knowledge of the others. Still, after experiencing how strong OPUS: Prism Peak is, I’m definitely tempted to dive into the rest of the series. It seems clear to me that SIGONO INC. has taken the time to develop and hone their craft. They put passion into this game as seen in its narrative, design and gameplay. Not many games I review ever get touched again once I finish writing. This one is certainly not going to fall in that category.
If your a gamer that must have action or combat in your games to have fun, then sure, this one might not be for you. However, for anyone else, especially those like myself who love narrative based games, then I can happily recommend this one. I really enjoyed the game’s narrative and the story building it does with its spirit realm setting. The characters are thoughtfully crafted, both narratively and in their in‑game presentation. I could easily see this game having a film adaptation. Gameplay mechanics are also quite enjoyable. It was fun to explore each area, snapping photos and learning more of the lore. I enjoyed solving the puzzles in the field journal as I pieced it together. Overall, it’s a remarkable game, and it earns every moment of attention you give it.
Thank you for reading, now go take some pictures!
