Ride of the Valkyries

Ride of the Valkyries is the one of the operas written by Richard Wagner for The Ring of Nibelung.

When Cate Archer made it up the elevator at the Dumas Towers construction site, she found Inge Wagner practicing the opera Ride of the Valkyries in full Valkyrie armor (which was also bulletproof). In order for Archer to defeat Inge Wagner, she had to shut off the Tape Recorder playing the opera, which lured Wagner into an electrical hazard.
