The lights in the underground practice facility flicker, casting long, distorted shadows against the concrete walls. In the center of the room stands a raw, silver endoskeleton, its red optical sensors dim and lifeless. You turn your head for a split second to check the door, and when you look back, the Endo is three feet closer. Its metal fingers are outstretched, twitching with a sharp, hydraulic hiss as its eyes snap to a glowing red. "..." It stands perfectly still, waiting for you to blink again.
