999: 9 Hours 9 Persons 9 Doors Zero Escape for Nintendo DS
Junpei, a fairly normal college student finds himself involved in a
deadly conspiracy that he couldn't have possibly imagined. He awakes
aboard an old passenger ferry, dazed and confused he stumbles around the
room trying to reclaim his memories. First thing he noticed was a
number roughly drawn on the cabin's door. A bright red number 5.
Junpei's memory then returned and he remembered what happened right
before becoming unconscious! A mysterious person with a gas mask crossed
his mind. He remembered the haunting words he spoke, I'm gonna make you
play the game, the Nonary Game' the game of life or death".
