Eagle-eyed Siliconera found a listing on Gamefly for Chunsoft's Extreme Escape: 9 Hours, 9 Persons, 9 Doors. Great name. Spooky graphical text adventures in my North American DS? Craziness!
Of course, a Gamefly listing (leak) would point to a US release. Now Aksys confirms it. Here' they'll be calling it 999: Nine Hours, Nine Persons, Nine Doors. It tells the story of nine people trapped on a cruise ship with bombs inside them. Yes, inside their bodies. They'll have to work together to not explode. Get ready for a lot of blowing up as there's 999 possible endings.
We're waiting to hear more about release dates and such, and will let you know as soon as we do.
