Professor VS Gyakuten saiban -- the Japanese name for a new crossover 3DS game that features both Phoenix Wright and Professor Layton -- was revealed last night by Level-5 during a press conference in Tokyo. The game is being developed in collaboration with Capcom, though Ace Attorney creator Shu Takumi will be heading up writing. It appears that this marks the beginning of Level-5 and Capcom's much teased collaboration, and one of the four surprise titles Level-5 said it would reveal during its Vision 2010 event currently taking place in Japan.

1UP's liveblog details the gameplay of Professor VS Gyakuten saiban as a "combination of puzzles and crime mystery," while Level-5 president Akihiro Hino characterizes the collaboration by comparing it to "two TV shows getting together and making a movie." The game's official website is scheduled to open officially on October 20, but Andriasang already has some images of the game and we've embedded a shaky cam video of the reveal trailer after the break, courtesy of 8-4's Mark MacDonald.
