Nintendo has officially unveiled Detective Pikachu: Birth of a New Combination, a 3DS game starring a crime-solving Pikachu who wears a Sherlock Holmes-style hat.
It's been more than two years since an early tech demo for the title was glimpsed - all the way back in October 2013. It showed an actor mo-capping facial animations while Pikachu nattered away in Japanese.
The trailer below - which, believe me, is extraordinary - shows the walking, talking Pikachu and his human companion solving crimes.
Detective Pikachu will launch via the 3DS eShop on 3rd February in Japan priced 1200 Yen (Ł7.10) for three weeks, then 1500 Yen (about Ł8.80) thereafter.
The subtitle suggests this will be the first part in a series. We're asking Nintendo UK for more details now - including when we'll see the game here in the West.
