Now, you might be thinking 'Who in God's name is this Freekopolis?' and I wouldn't blame you. I'm not exactly the most active forum member, but I can assure you I'm a fanatic Destructoid reader.
The thing is, I've gotten myself a US 3DS via PK Fire about 10 months ago and have been using it like a mad man. Now, the Humble Nindie Bundle just showed up and I obviously bought it for the 3DS games. The Wii U codes though? Not much use. So I thought I might as well post them here. If you use one, please mention it below, so other users aren't disappointed when they enter one and it's invalid.
