Aksys wasn’t at E3, but they have new games to announce at Anime Expo. One of them is (probably) 999: 9 Hours, 9 People, 9 Doors, a mystery game for the Nintendo DS from Chunsoft. Gamefly just leaked it.
9 Hours, 9 People, 9 Doors chronicles nine characters trapped on a luxurious cruise ship. You have to help them escape by solving touch screen puzzles. The escape the room mechanic is only half of the game. 999: 9 Hours, 9 People, 9 Doors also has a novel-like story to follow.
Chunsoft, the makers of the critically acclaimed 428 and Shiren the Wanderer created this puzzle game meets visual novel blend. Look for it on the Nintendo DS later this year.
