Whilst wandering through a decrepit area of the bunker, you hear a sound of a scream before an abrupt, loud bang.

The scream stopped after.

You went over to investigate, only to find... Doll. She was dead on the cold ground, her chest broken open to reveal her mechanical yet still oddly fleshy insides. Her face was half smashed, with her oil mixed with blood trickling down her face as she laid unconscious.

You couldn’t believe what you just found, as you feel to your needs, a sound was made. It was coming from inside Dolls opened chest

Then, a small fleshy blade sticks out. Which is then followed by another fleshy blade, then you see this small fleshy blob climb its self out off Doll's dead corpse and say its self on top

You see that this…small blob only has one eye and three fleshy blades, it looks both fleshy and mechanical. Then it notices you and looks up at you with its red eye

(this is her core, or her disembodied heart btw)
