The news has been confirmed by an OFLC rating, which was submitted on the 8th August. Interestingly, it lists the game as Virtue's Last Reward, omitting the Zero Escape portion of the title.
A curious mixture of visual novel, graphic adventure and puzzle game, Zero Escape looks set to be as unique as its predecessor. Aksys Games is publishing the title in North America, with 24th October being the last confirmed release date.
Rising Star Games has yet to give any confirmation of when it intends to bring the game to Europe and Australia, but we'll let you know the moment it does. In the meantime, the trailer for the Japanese version of the game can be seen below.
EDIT: Rising Star Games has officially confirmed the release on its Facebook page.
