Japan's 3DS eShop is getting the NES classic, Metroid, next week on February 29. Metroid is one of many free NES titles available to qualifying 3DS Ambassador Program participants (i.e. early 3DS adopters). Everyone else will have to hand over ¥500 ($6) to navigate the deadly wilds of the planet Zebes once again.
