"Yeah, you told me." Alice ground her teeth in frustration and let the stims push away fatigue. She reached into a small pocket on her left hip. The camera drone was the size and shape of a black marble. She squeezed until it beeped, then threw it high into the air. It wobbled, emitted a low-pitched chatter, then shot toward the prone body. Alice pulled her visors from an inside pocket. The left lens was split in two, but she donned them anyway. They sagged to one side as the right lens stuttered to life, snowstorm interference pixelating before it became a recognizable video feed. The drone showed her an augmented world view—the street ripped past in a blur, visible light supplemented by crimson infrared hotspots and cyan millimeter-wave radar.
