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"):
