Battle Mii was a tech demo for Nintendo's Wii U that was shown at E3 2011. In the demo, two Miis dressed as Samus from Metroid ran around a large level while shooting enemies, targets, or each other. Additionally, a third player could control Samus' gunship and attempt to defeat the other two players.
In the 2012 Wii U launch title Nintendo Land, there was a minigame called "Metroid Blast" that expanded and refined this concept. However, the original tech demo has never resurfaced.
