Sam readied the rifle. She armed herself as one would with an ordinary rifle, but instead, she put her left hand onto the side of it, where the keys were. She played a specific sequence to "wake" the rifle. She aimed it towards a stack of beer cans that a couple of teenagers had made an hour or so ago. She played another sequence that sounded like a snatch of electronic music. On the last note, she held the key, and a blast of light shot forth from the barrel of the rifle. It annihilated the cans and the wall behind it, blowing a perfectly round hole in the wall and the wall of the building behind the nightclub.
