Nine Hours, Nine Persons, Nine Doors
999: Nine Hours, Nine Persons, Nine Doors is a Japanese visual novel and adventure video game developed by Chunsoft. It is the first installment in the Zero Escape series, and was released in Japan in December 2009 and in North America in November 2010 for the Nintendo DS. The story follows Junpei, a college student who is abducted along with eight other people and forced to play the "Nonary Game", which puts its participants in a life-or-death situation, to escape from a sinking cruise liner. The gameplay alternates between two types of sections: Escape sections, where the player completes puzzles in escape-the-room scenarios; and Novel sections, where the player reads the game's narrative and makes decisions that influence the story toward one of six different endings.
