While Level-5 previously confirmed a western release for Layton’s Mystery Journey: Katrielle and the Millionaires’ Conspiracy on mobile devices, the game’s 3DS version remained in limbo.

Now, we’ve learned the Nintendo 3DS version is getting a western release as well, sometime this fall. The iOS and Android version is set for a worldwide release on July 20th.

Here’s a rundown on the game, via Level-5:

Formerly titled Lady Layton: The Millionaire Ariadne’s Conspiracy, this new installment of the Professor Layton series is a strategic mystery puzzle solving game that follows Katrielle Layton, who searches for her missing father Professor Hershel Layton.

The new title is an exciting departure from previous games in the Professor Layton series as it is made up of a combination of smaller conundrums and puzzles that need to be solved in order to complete the overall mystery. This new format is going to appeal to existing Layton fans as well as attract a brand new audience.

Level-5 says also noted the Professor Layton series has sold over 16.0 million units worldwide.
