The game follows Takeshi Kuranari and a boy with amnesia who is referred to as "the Kid", who are trapped inside an underwater theme park together with a group of other people after a leak has flooded parts of the park; they cannot contact people on the surface, and due to high water pressure, the park is estimated to implode after 119 hours. The gameplay consists of the player reading the game's story, at certain points making choices that affect its direction, leading to one of several possible endings.
The development team included director Takumi Nakazawa, writer and planner Kotaro Uchikoshi, character designer Yuu Takigawa, and composer Takeshi Abo. Because the science fiction aspects of Never 7 had been positively received, Ever 17 was made with a larger focus on science fiction. The game has been positively received, with reviewers calling it one of the best in its genre, citing its story, characters, music, and graphics.
The game opens on May 1, 2017, when a blackout occurs in LeMU, its communications system go down, and the park springs a leak; portions of it get flooded, blocking the exit and trapping the characters. Due to water pressure, the park is estimated to implode after 119 hours. The pressure also prevents escape by swimming, as it would crush one's lungs.
If the player plays as Takeshi, he builds a relationship with Tsugumi, who reveals that she and her pet hamster Chami are carriers of the Cure virus, which has rewritten their genetic code and halted their biological aging. She and Takeshi have sex, and she becomes pregnant. Later, Coco becomes sick. It is revealed that LeMU was created by the Leiblich Pharmaceutical company as a cover for IBF, a research facility underneath the park. IBF developed the deadly virus Tief Blau, and the LeMU disaster was caused when IBF lost containment of it. Coco was exposed to the virus while visiting her father, an IBF researcher.
The group goes to IBF in search for a cure, but starts showing signs of Tief Blau. An exception is Tsugumi, as the Cure virus has made her immune; the group injects themselves with her antibodies. They get contact with the surface, and a rescue pod is sent down, but is only able to stay for a short time. Tsugumi leaves to find Chami, who has gone missing; Takeshi chases after her, and saves Sora's data onto a disk to save her memories. Returning to IBF, they have missed the rescue vessel. They find a submarine and escape, but its batteries die; Takeshi exits it, giving it enough buoyancy to save Tsugumi, while he drowns on the ocean floor. Coco dies in IBF, as she had been looking for Pipi, and the rescue team could not find her.
