999: 9 HOURS, 9 PEOPLE, 9 DOORS (NINTENDO DS)

Waking up, unsure of his whereabouts, Junpei discovers a watch-like device strapped to his wrist with a numeric "5" on its face. Trapped inside the room with the only exit being a solid steel door with an ominous blood red "5" painted on it, Junpei has little time to observe his surroundings before a porthole cracks open and the water does not quickly begin to flow. As he escapes, pieces of memory return, including a strange figure in a black cloak and gas mask known only as Zero. He soon encounters eight other people aboard what they soon discover is a huge ship. Who are they, why did Zero bring them here, and what is this strange game Zero decided to play with their lives?

Nine Hours, Nine Persons, Nine Doors is an adventure game with two different playstyles. The first is a traditional Japanese "Visual Novel" style game, where most of the game is devoted to reading text, with occasional choice selections prompted at times. However, unlike most visual novels, the majority of choices presented in the game send the player down different paths, leading to different areas of the ship, ultimately leading to one of the game's six different endings. Depending on the how the player reacts, other characters change their attitude or personality, and different events will occur. In the narrative sections, characters and dialogue are displayed on the DS's upper screen, while a narrator describes thoughts, feelings and actions on the lower screen.
