Nintendo consoles have been privy to some incredibly unusual controllers in their time, most of which are a bit rubbish and don't really improve gameplay in any way. However these previous blunders haven't deterred Grendel Games from designing a Wii U eShop game called Underground and an accompanying controller to accurately replicate necessary skills for keyhole surgery.

The device requires two Wii Remotes and Nunchuks and allows the user to move the arms in-game so that their movements are immediately replicated on screen. We've even managed to get our hands on one such controller in order to be able to show it to you today, so make sure you cast your eyes over the video below to see this peculiar and specialist device in action.

You can learn more about Underground and its ludicrous input device by checking out the game's website.
