本作是2000年发售至今仍然大受好评的「infinity」系列的最新作。 　　继承了「infinity」「Never7」「Ever17」的世界观的作品。 　　贯注于Infinity历代作品中的数字的含义。这次的「11」究竟有何含义……？ 　　主要角色，舞台全部重新制作。 　　虽然继承了世界观，但故事本身与前作并没有直接联系。 　　本作的舞台与前作处于不同的时间和地点，故事是独立的，即使是从本作开始游戏，也不会有不协调的感觉。 　　当然，如果曾经玩过前作，便能够更加深入地融入本作的故事剧情。 　　本作分为「こころ编」和「悟编」2个剧本。 只有先将「こころ编」通关之后才能玩到「悟编」。 　　当玩家完成全部2篇剧本时，便可以体味到将本篇错综复杂的谜团解决的达成感。 　　本作不是恋爱AVG。 　　真正的目的在于了解故事的全貌，换句话说就是在游戏中生还。 　　当一切都结束时……玩家将体会到成功生还的达成感和感动。

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.
