The Nintendo 3DS's Circle Pad Pro attachment, which was announced back in September, has now received an official release date in Europe. It had previously been hinted that the peripheral would release in January alongside Resident Evil: Revelations and this has now turned out to be true.
Gamers will be able to purchase the peripheral in a similar fashion to Japan's Monster Hunter 3G, meaning that it will be bundled up with the new Resident Evil: Revelations.
Players will be able to use the peripheral for things like camera movement. The attachment also has an extra trigger to use.
You can purchase the Circle Pad Pro with Revelations or separately starting January 27th. Just note that this attachment requires an AAA battery.
