The game follows Fuyukawa Kokoro and Yukidoh Satoru, who frequently experience a phenomenon that makes their minds switch place with each other, putting them in the other person's body.

Kokoro is stuck in a blizzard in an emergency cabin on a mountain together with three other people, while Satoru is in an institute for the treatment of mentally ill criminals, having lost his memory.

The development team included director Takumi Nakazawa, scenario writer Kotaro Uchikoshi, music composers Takeshi Abo and Chiyomaru Shikura, and character designer Hidari.

[2] Remember 11 takes place in 2011 and 2012 concurrently, from January 11 to January 17, in two places in Japan: an emergency cabin on Mount Akakura in the Hakkōda mountain range, and the Specified Psychiatric Hospital for Isolation and Aegis (SPHIA) institution on the fictional island of Aosagi, in which mentally ill criminals are treated.

The player takes the roles of Fuyukawa Kokoro, a third-year sociology major who is stranded on Akakura after surviving a plane crash, and Satoru Yukidoh, who lives in SPHIA and has lost his memory.

Among other survivors of the plane crash are Mayuzumi Lin,[h] a lawyer and the girlfriend of Satoru; and Yomogi Seiji,[i] a professional mountain hiker.

The game begins in 2011 with Kokoro traveling to SPHIA to interview Inubushi, when her plane experiences turbulence and crashes on Mount Akakura.

In the cabin, a news article dated July 4, 2011 is found, which says that Yuni was the only survivor, with the other three having died in an avalanche on January 17.

As the week goes on, the people in the cabin are running out of food, while Satoru is subjected to multiple attempts on his life by an unknown assailant.

As days pass, Satoru notices that he can see the same lunar phase at SPHIA and at the cabin and that both areas are surrounded by a body of water.

Satoru finds a locked room in the basement of SPHIA, where he encounters a man named Enomoto, monitoring the facility through cameras.

Satoru reviews his theory regarding Inubushi; he thinks that she, too, was experiencing the transfer phenomenon, and that her consciousness ended up at Mount Akakura in the dying body of Hotori.

The game was directed by Takumi Nakazawa, while Kotaro Uchikoshi was in charge of the scenario writing,[1] and Hidari designed the characters.

[15] Remember 11 was originally released for the PlayStation 2 on March 18, 2004, in both a standard and a limited edition; the latter included a booklet with material related to the game, and a "special voice CD".

[16] An updated version of the game, with seven new CG sequences added, was released by Success in 2005 as part of their budget series Superlite 2000.

[21][22] A music album with the game's soundtrack was released on March 24, 2004, by Scitron, with the title Remember 11: The Age of Infinity - Sound Collection.

[14] He called the character designs "excellent" and distinct from those in previous games in the series; he found it interesting that the character designs in previous games, which took place in "watery" settings, had brighter and less earthy colors, while Remember 11, which takes place in the mountains, makes more use of earthy colors.

He said that it is unmistakably the work of Abo, but improved over his previous soundtracks, and having "enough layers of experimentation to showcase musical growth" for it to not feel formulaic or like a rehash.
