P-Body, having her original chassis based on a Sentry Turret, was nearly impossible to wake after shutting down. After using the Frankenturret to dent the door, before having to resort to powering down the entire room, and powering it up again. P-Body's room was similar to Atlas', but instead of pictures, Blueprints to Atlas, P-Body, Sentry Turrets and even GLaDOS covered her wall. An Old Cookbook of Cakes sat in the corner where Atlas' Companion Cube stayed and Opera played from her Radio. She woke with a start.
Atlas communicated to her in a quick few bleeps and whirs, and she grabbed her Portal Gun, which had Orange trim. They walked out past the turrets and towards the broken door.
"The Rat and the Heart hold the key." The first turret said.
"Hello. Thank you for your business." The other said.
Thankfully, the second turret was programmed not to shoot at them, and the first didn't seem aggressive to anyone or anything.
Atlas pressed the red button to Testing Area G9, and P-Body pried to wires from the door system and sparked them together. The door opened and closed repeatedly, smashing all bits of rubble between the doors together. Atlas fired his Portal Gun through the doors as they opened, and fired against the ground. He jumped into the portal and hopped out, inside the Testing Area G9. P-Body followed soon and they walked along the deserted hallways. There was a red stain along the fall and a Skeleton in a white lab coat with an outstretched, skeletal hand.
They walked forward, and came across several Turrets blocking the hallway. P-Body ran across and fired her gun, and two portals appeared, causing a turret to fall through the fall and appear above another turret, causing them both to fall and knocking out another turret with the gunfire. Atlas poked his head out, and noticed the remaining two turrets were offline, with two dents in their body. Atlas walked alongside P-Body, and kicked over the offline turrets, before the door behind the turrets opened, revealing a room filled with Blueprints, Sketches and Diagrams of Robots. Some were larger than Normal Turrets, Square Personality Core's with legs, and even a few that looked similar to Atlas and P-Body. But what surprised them was the electronics. Countless Robots and tools lay across tables, along with three skeletons. There was no electricity, so the bots were all offline.
Atlas noticed a CD lying on the floor, and an old disc holder like the ones that gave GLaDOS access to the Human Vault, so he picked up the CD and put it in.
