Level-5 will be releasing their 3DS launch title Professor Layton and the Miracle Mask in an upgraded form on the Japanese eShop.
The revised game, known as Professor Layton and the Miracle Mask +, will arrive on February 6 and boasts a variety of enhancements. News of this release comes from Famitsu, as reported by Siliconera. It will sell for 3,000 yen.
The bonus content of this upgrade includes new events, new puzzles, additional animation (the original Famitsu article is unclear on whether this means character animation, in-game cinematics, or animated cutscenes), a new tutorial, and all 365 download puzzles unlocked from the start. As well, the game will provide further hints to solving puzzles in the game's Ruins segment, a sequence where Layton solves puzzles from an overhead perspective. In these ruins, players control Layton and Randall carefully avoiding monsters and traps, pushing boulders to create new routes.
No plans have been announced to release this version of the game outside of Japan.
