Square Enix has joined forces with…Amazon…for a special promotion involving Final Fantasy Type-0 HD. Basically you go online daily to this site, and “battle” enemies in a group effort type deal to earn prizes.
The rewards range from physical goodies if you’re lucky, to guaranteed digital drops if enough people play. All you need to do is go to the site, log into Twitter, and accept the app. To “attack,” you need to post a tweet.
