Skyward Sword has been out for almost 2 months now and the game is readily available at most major retailers. However what is not widely available is the Skyward Sword Demo Disk. If you have the game then obviously the demo is worthless. However, a hardcore Zelda collector may find this to be a must have.
The demo disk can be found on eBay now and though we cannot offer a walkthrough for the demo, we do have a growing Skyward Sword Walkthrough that you may find helpful.
