If you’ve been keeping up on our coverage of Etrian Odyssey IV, you may be interested in this wallpaper that was made based on the game’s Japanese box art. There’s several sizes available at the game’s site, depending on your screen resolution.
We also mentioned that the game will make use of QR codes for various reasons, the first of which you can check out in the blog post with the wallpaper. Once you have the game loaded on your 3DS, you can access a special area that works as a QR code reader, to unlock hidden in-game items for your use. Pretty nifty, no?
