VR Battle Chess Demo - Similar to Harry Potter wizards Chess

Using Oculus Rift the user will begin standing in the middle of the chess board. The user can see the chess pieces on both sides of the board. The chess game will begin and pieces will begin moving fighting and capturing one another while the user is standing in the middle of the action. The entire demo will last about 1 minute and 45 seconds. The chess pieces will be realistic and animated and when the chess pieces move to overtake one another it will become a battle chess likeness with the use of weapons and magical powers. The chess pieces will appear larger than the user. The chess pieces will also need to be created with character. Audio needs to be intense with realistic battle sounds, for example, magical power sounds, swords clashing etc. The demo will end with a check mate in slow motion so to enhance the intensity of the final blow to the king. I'm thinking the chess board will be located inside a cave or some dark ruins, with a few torch fires burning in the background. The user will be able to move around a little bit so to move out of the way of chess pieces and weapons being thrown in their direction. The graphic quality needs to be realistic and very high end. I’m looking for a demo in a similar style to the demo Showdown. Please see link below I'm definitely open to creative ideas on how to make this a great demo and what the environment should look like.
