Utterly Mad

Sammy:
You sneak on over to the door, and have a little peak inside.

Inside lies a promised storage room, with several shelves holding some batches of spare parts and the like.
But there's also some interesting items on a shelf in the back.

Although, that would mean that you'd have to deal with the security robot in the middel of the room. It's a treaded model, with a small machinegun-turret.

Then lucy goes on ahead and opens the door unhindered.

Sammy & Lucy:
As Lucy goes on and opens the door wide open, the security robot starts beeping, followed by it opening fire on the doorway.

Luckily, you both hit the deck as the lead starts flying on overhead.

You note that the only thing stopping you from being turned to pulp is a flipped shelf between you and the robot.

After remaining out of sight of the robot for a moment, it stops firing. And luckily it also seems like it isn't moving.
