UPDATE - Yanked from North American shop as well
IRONFALL Invasion is temporarily unavailable on Nintendo eShop. Apologies for the inconvenience. Stay tuned for more information.— Nintendo of Europe (@NintendoEurope) August 11, 2015
I think we all know why this is happening. Looks like we won't be using this title for any sort of homebrew or region-free gaming in the near future!
