A lot of the early stuff is a pretty big gray area of no information.
PSA: Hey guys, do you have a 3DS? Do you want a Free Awesome game, key word FREE? The Legend of Zelda Four Swords Anniversary Edition is back on the Nintendo eShop for a limited time. Not only is it back, but it's also FREE!
So want a Free Zelda game? Turn your 3DS on and get to downloading cause this game shall only be on the eShop for 4 Days (Get it? Cause it's like, 4 Swords and....... Shut up)
Anyway yay free games, have fun, more PSAs later.
You might want to look into this. Last time they had this game in the eShop was December of 2012. Hasn't been back until now, and it's very limited time. Better get it. Nothing is cheaper than free.
