Yomei Kensaku Sābisu X-Day (余命検索サービス X-DAY, lit. Life Expectancy Search Service X-DAY), also known as simply X-Day, is a quiz arcade game developed and released by Namco in 1993 in Japan only. It is currently one of the few Namco games to not be emulated in MAME and is based on human survival in a post-apocalyptic world. A sequel title, Ren'ai Jumyō + Nikutai Jumyō X-Day 2, was released two years later in 1995 and also ran on Namco NA-1 hardware; and, much like its predecessor, is currently unavailable in MAME. Soundtrack albums for both games were released by Victor Entertainment in 1995 under the Namco Game Sound Express label.

Gameplay

Once the player enters their name and gender, his/her "life expectancy" bar is set with five different categories; "Eating", "Body", "Heart", "Ring" and "Technique". Each question will randomly select any category and ask the player a question relating to that category, and the player must move the joystick left for "yes" or right for "no". If a question is answered correctly, then the player's "life expectancy" bar is raised a level; but if the player should fail to answer the question correctly, then his or her life expectancy bar will instead deplete a level; a level will also deplete from the bar if the player does not give an answer in a given time limit. When the player manages to answer all questions, if the life expectancy bar is positive, then the cabinet will print a small certificate congratulating the player; but if the player answers all questions but their life expectancy bar is negative, then a "zombie certificate" will print and states that the player has failed. In both cases, once the player answers all questions and the game determines the outcome, the game will be over.

Sequel

A sequel game, titled Ren'ai Jumyō + Nikutai Jumyō X-Day 2 (恋愛寿命+肉体寿命 X-DAY 2, lit. Love Lifetime + Body Time X-Day 2), was released two years after this game's predecessor in 1995 and it also ran on Namco NA-1 hardware like the original title. The game is heavily centered around love, with the player now having a "love life" bar as opposed to having a life expectancy bar. The "love life" bar measures the remaining days of love between two individuals, which can be either male or female.
