Aquanaut's Holiday: Hidden Memories (AQUANAUT'S HOLIDAY ~隠された記録~ Aquanaut's Holiday: Kakusareta Kiroku?) is a PlayStation 3 game developed by Artdink and published by Sony Computer Entertainment. A Japanese version was released in Japan and South East Asia region on September 25, 2008. A translated "English + Chinese version" (Aquanaut's Holiday ~堡礁秘辛~), was released in South East Asia on November 20, 2008.
The game is currently only available in Japan and South East Asia (Hong Kong, Taiwan and Singapore), however the Asian version was re-released in November 2008 with Chinese and English languages replacing the original Japanese. Given the fairly simple game play, the English version is understandable for teens and older players, but young children may be confused by the significant "Engrish" evident in the translation. The English language version is also available in Korea.
The actual story mode of the game can be compared to an adventure game. The main - unnamed - character is a journalist, in search of the missing oceanographer William "Bill" Graber (ウィリアム（ビル）・グラバー?). Using a submarine called the Dolphin no.2 you explore the seas for clues.
The game takes place in Kisira Atoll, in Polynesia. An oceanographic research facility named Kisira Base is the starting point and where you always come back to, for supplies (such as batteries for sonar navigation buoys) and equipment.
Two scientists work at the base, the young and dreamy Jessica Porter and the conservative chief Robert Kemelman. Both assist you in solving mysteries, each in their own way. Jessica likes to believe fairytales and legends, while Robert usually comes up with a scientific explanation.
All the fish, animals and other discoveries are added to a database. Some fish can communicate and the player has to repeat the sounds made by a fish, using the four trigger buttons of the Sixaxis controller.
At all times, the unlocked area of the map is free to explore as you like.
