Ghost Watch has been shrouded in a mystery ever since it was shown by Level 5 last year. According to Coro Coro, Japanese video gaming magazine, Ghost Watch is set to be released on the 3DS. The game follows the adventures of a young boy who possess a watch which allows him to see and befriend ghosts.
There is no release date mentioned in the magazine nor have they shed the light on the fact, whether Ghost Watch will be released in the west or not. When Level 5 debuted Ghost Watch, they defined it as another multimedia franchise just like the Inazuma Eleven and The Little Battlers eXperience.
Here is the debut trailer from last year. It is not in English though so it may not make sense to a lot of people.
