Jacob crept through the hallway past the door, rifle at the ready and pointed strait down the corridor. He reached a set of doors, one on either wall to his sides, and took the one on the left and motioned for GU-DR to take the one on the right. He held up three of his fingers, lowered the number to two, then one, and opened his door. Inside he found an abandoned office, totally devoid of life, the lack of shooting from the other room indicated that GU-DR seemed to have found something similar. The most interesting thing in the room was it's stench, which Jacob attributed to the skeleton in the corner. He moved over to the desk and opened the drawers, finding them completely empty. He shut them in disappointment and reentered the hallway to find GU-DR waiting for him.
"Anything?" Jacob asked.
"No sir, no hostiles detected through visual scans or infrared scans."
"You have infrared? I don't remember installing that."
"I was built with it installed sir!"
"Why didn't you ever tell me? And don't say-"
"You never asked sir!" Jacob glared angrily at the robot, then bashed at it with the butt of his rifle. "Sir! Friendly fire!"
"Shut up! Scan the rooms, all of them right now before I use you for scrap metal!" The robot responded by extending it's sensors and looking down the hallway, then immediately turning back to Jacob.
"No enemies detected in the corridor sir!" Jacob's eye twitched angrily.
"I didn't say scan the hallway, I can see the hallway, I said scan the rooms!"
"I cannot from this position!"
"You just said you had infrared vision!" Jacob was becoming annoyed at this point.
"My scanners cannot penetrate concrete."
"Penetrate, what do you mean penetrate?! Infrared scanning detects heat signatures! Concrete shouldn't matter!"
"My ultrasonic waves cannot get through concrete as they bounce off too easily." the robot responded a bit too proudly for Jacob's taste.
"Ultrasonic." Jacob said in a deadpan voice.
"Yes sir!"
"Thats SONAR wire brain!" striking the robot once more. "Then go to each door and scan the damn rooms. And when we're done here you're getting a crash course in just about damn near everything!"
"By your command sir!"
"Pre-war junk." Jacob groaned, exasperated from the sheer stupidity of his robot, and waited as the Mr. Gutsy floated in front of each door, opened it, and looked inside before moving on.
