Dragon's Lair

This should be unlocked after the "Bumbling Knight" trophy. You'll be required to complete new game in it's entirety (kill the Dragon) in order to obtain this trophy, so it's best to play through an Easy game on either Arcade or Home mode. At first though, expect a little trial and error. It's a good idea to save your gave frequently so you can reload a previous save file. This will especially come in handy for some of the trickier trophy requirements.
