Mighty Switch Force: Hyper Drive Edition (or Mighty Switch Force HD for short) is an extension of the 3DS download version that is currently on sale at the Wii U eShop. Despite that the Wii U eShop is not promoting it on their front page, the sale went down from $9.99 to $6.99 (almost the same price as the 3DS download version) and no indication of when the sale will end.

If you're a Wii U owner and haven't experience Mighty Switch Force, then be sure to read my review of original 3DS download title by clicking here before deciding to take the offer.
