Sega's classic Shinobi will be making a comeback on the Nintendo 3DS. It's not been officially announced yet, but American Nintendo Power has confirmed on their Twitter-account that they will feature the game in the next issue of their magazine.
According to Superannuation, the developer is Griptonite Games. Last we saw anything from Shinobi was back on the Playstation 2, which we promptly chose to forget all about (because it wasn't very good).
