Ever17: The Out of Infinity

Ever 17: The Out of Infinity is a visual novel video game developed by KID. It is the second entry in the Infinity series; it is preceded by Never 7: The End of Infinity, and followed by Remember 11: The Age of Infinity, 12Riven: The Psi-Climinal of Integral, and Code_18. From VNDB: "Ever17 is the tale of seven individuals who come to be trapped 153 feet within the underwater marine theme park, LeMU. During an apparently normal day at the park, a massive accident happens, placing almost half of the facility underwater. The path to the surface and the communication lines are cut off. In addition, LeMU is under constant assault by severe water pressure, limiting time to find a means of escape to 119 hours. Escape is not the only concern, however; many questions arise as to the legitimacy of the accident and whether or not those trapped there were brought there for a purpose." 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.
