Fight fire with fire? This goes against all elemental rules in every videogame ever, but as the hero in Dragon Blade: Wrath of Fire, you'll be using the fiery powers of dragons to wipe evil beast-men off the planet. Through five worlds of four levels each, you'll quest for the six pieces of the legendary dragon blade. Each mini-boss you defeat in a level adds a new dragon bit to your collection, which you then use to slay a huge dragon at the end of each world.
For most standard enemies, though, you'll want to use your sword to keep the Dragon Power meter filled. The Wii Remote controls are basically just what you would do in real life (that is, if you were a swordsman). So if you want to slice your sword from side to side, stab, or slash up and down, you just make the analogous motion and the character on-screen does the same.
