Aquanaut’s Holiday: Hidden Memories

Aquanaut's Holiday: Kakusareta Kiroku (as it's called in Japanese) is a sequel to the Aquanaut's Holiday game series which began on the first Playstation in 1995. In this version, you play a journalist searching for a missing oceanographer named William "Bill" Graber. With the help of two scientists, Jessie and Robert, you take control of the Dolphin 2 submarine to explore the sea for clues, while cataloging every sea creature you find.

The game is in first person, with beautiful graphics and a calming soundtrack. Though never sold in North America or Europe, the Hong Kong and Korean versions do contain "Engrish" subtitles. With the walkthrough, it's possible to obtain the Platinum using the Japanese-only version, though you may get frustrated at times.

For the most part, this game involves a lot of searching and finding. Sometimes the finding can get pretty frustrating, especially when you're looking for a teeny tiny fish within this great ocean. Without a walkthrough or guide, this game is nearly impossible. Luckily, we've managed to find a few in English for you to use. With the help of the links, the game is not as difficult as, say, GTA IV. But will take a lot of time hunting those waters to catalog sea life.

For the most part, simply go through the story and explore new regions of the sea. You'll be replacing batteries in new Sonobuoys to allow you to venture farther, discover treasures in side-quests, and find clues as to the whereabouts of Bill Graber. Make sure to speak with Jessie and Robert each time you surface, to allow new clues and treasures to spawn. Should you complete the story but not locate all the fish - don't worry! After the credits scroll, you'll be returned to your submarine. There are no missable trophies in this game.

The "Singer Fish" work like the Simon electronic game in the 1980s. Using the R1&2 and L1&2 buttons, you must match the patter of the fish's song. As they become quite difficult later in the game, it's a good idea to start writing down the patterns than rely on memory. There are 20 Singer Fish in the game (which means 20 trophies) and each fish as 20 levels to complete. As a tip, place a NaSU near the Singer Fish, so that after completing its level, you can warp out, then warp back - the Singer Fish will automatically respawn, allowing you to try the next level.

Since this game was never released in North America or Europe, there hasn't exactly been a mountain of guides and walkthroughs. But we have found you some, hopefully enough to unlock the Platinum.

First, here is a story Walkthrough by kuraki-dan and Jaytech. They include a map, as well as the Japanese script for sea and fish names, in case you're not playing the "Engrish" version:

Here is a Trophy Guide, which includes all the patters for the Singer Fish:

This is a guide for finding the "tricky" fish and items - meaning they come and go, depending on which cycle you're on. First, this is the Guide for the Cycles (translated into "Engrish"):

Aquanaut’s Holiday Hidden Memories Review

The Game:

Known as Aquanaut’s Holiday: 隠された記録 (Aquanaut’s Holiday: Kakusareta Kiroku) in Japanese, the game was released in Japan in September of 2008, and never saw an international release. Though there exists a Hong Kong version which contains “Engrish” subtitles, Hidden Memories is relatively non-existent in the West.

The title is a sequel to Aquanaut’s Holiday released for the Playstation One back in 1995, which DID see an international release. So why not Hidden Memories? Who knows. Artdink, the game’s developer, perhaps felt this title wouldn’t sell overseas. Or, since big titles like Grand Theft Auto IV were just released, Artdink felt they couldn’t compete with a game about fish – and has since been forgotten (yes, that happens). Whatever the reason, Hidden Memories received fair success in Japan, and was the first Japanese-only title to have trophy support.

Aquanaut's Holiday Hidden Memories ReviewYou play as a journalist (whom you never get to see) investigating the disappearance of oceonographer William Graber, at a base in Polynesia. The game can be divided tinto two views: there’s the research base, which basically looks like a photograph, where you can chat with to scientists, Jessica Porter and Robert Kemelman. Then, there’s the first-person water exploration scenes.

Despite being a journalist, you’ve got a lot of oceanic work to do. You’re recording and cataloging every different species of fish, dolphin and whales to get cash for the base, which in turn you can use to purchase batteries for the sonar navigation buoys, allowing you to visit new areas of the ocean, and buying things called NaSu which allows you to “warp” to different locations.

While the main plot is to find clues leading to the whereabouts of William Graber, there are several side-quests along the way, such as investigating a sunken ship, and making contact with “singer fish.”


What I Liked:

For a game released relatively early in the PlayStation 3‘s life, the graphics of the underwater scenes are fantastic. Unlike Afrika, where the animals sometimes moved like mechanized creatures at a Disneyworld attraction, the flow of the fish and other aquatic creatures move smoothly with more realism than a Microsoft Window’s screen saver. Though the game is first-person, Artdink opted to NOT have a metal frame as though viewing through the window of the submarine. I thought this was a good call, as it allows the entire ocean to fill the screen, with the exception of your radar in the corner.

Eash “area” is different, and so it’s always exciting when you gain enough cash to purchase a battery for a sonar navigation buoy, allowing you to explore a new portion of the ocean. Some are shallow corral reefs, others are a maze of deep caves and tunnels, some contain sunken ships while others have strage faces printed in the sand. Weird. It would be fair to say Hidden Memories is an adventure game, for that’s what it feels like: an underwater adventure.

The story is engaging, beginning as a mystery surrounding William Graber’s disappearance, finding clues, then ending with an unexpected bang. I won’t spoil it for you, in case you have intentions of importing the Asian version with Engrish subtitles, but Hidden Memories is one of the few games which actually gave me goosebumps.


What I Didn’t Like:

My only real complaint is regarding the ocean base scenes. These are imperative, as sometimes you need to speak with the two scientists, Jessica and Robert, in order to move the story along. At times, you’ll be exploring the ocean desperately looking for something new, and not finding it. Well, you have to head back to the surface and talk to the scientists, which signal’s the game that you’re ready for something different – and only then do the underwater scenes change.

Aquanaut's Holiday Hidden Memories ReviewNow, that part I didn’t have a problem with. Underwater sandbox games like these need some kind of signal to start releasing new events for the player. What I didn’t like was the ocean base scenes themselves. It’s just a photograph. Even the two scientists are composed of talking pictures, which alternate between 3 different expressions, much in the style of the Japanese “visual novels.” And are you actually listening to them? Nope. Reading lots and lots of text.

The PlayStation 3 is a seventh generation gaming console. Seventh! Why are we still reading text? Even most Japanese “visual novels” use voice actors. This is a personal pet-peeve of mine, and I had the same issue with Yakuza 3. After awhile, reading all that text gets boring because you just want to play, so you start skipping through it, then you realize you’ve missed something important.

And that was another minor issue I had with these base scenes. In the beginning, both Jessica and Robert give you some useful advice, such as how to operate the NaSu or install the batteries into the sonar navigation buoys. But after a point, their “text-talk” becomes useless, other than maybe establishing character or mood. Jessica tells you ghost stories, while Robert goes on about his hopeful promotion. Why is this necessary? And why is it in text?



While the base scenes are dry and a bit boring, thankfully that’s not the main part of the game. The underwater scenes are great, and make you feel like you’re underwater as much as a video game could. Aquanaut’s Holiday: Hidden Memories is a fun undersea adventure, both relaxing and even educational at times, and all with an intriguing story to back it up.

It’s unfortunate this game was never released in the West, as it’s a title I would recommend to anyone who needs a break from shooting aliens and chopping heads off of zombies. For the most part, games are fun – but sometimes they can be pretty frustrating, raising your stress level. Hidden Memories is a stress reliever with its aquatic calming effect. If you’re interested in playing, you could try importing the Hong Kong version through the internet, which does contain Engrish. I don’t know how bad they are (I played this in Japanese) though I’m sure it’s enough to get through the game.

And no, you can’t shoot the fish to score points. I tried.
