Make her bald, no hair at all, not even eyebrows, nearly white as a ghost, like not Caucasian but almost to the point of unearthy. Don't explain ANYTHING about her. She's a force of fucking nature. She is the primal definition of selfishness, human survival and manipulation. Have her chase Ellie and Joel across the game, tormenting them. Killing their friends in brutal and horrific ways. Just absolutely heinous shit. When they ask her why, she just smiles.
At the end of the game, they think they manage to escape, with only Joel, Ellie and Ellie's love interest surviving. Some zombies attack and they get separated. You think she's ok, but out of the darkness, 'Judge' grabs her mouth and they both disappear into the darkness of the forest, just a stone's throw away from Joel and Ellie. Later a group of survivors find they body and are disgusted and horrified by what they see, but you don't show it or describe it.
The last scene is Joel and Ellie trying to confront her, but they're horrified at the sight of her naked, alone and dancing in front of a fire, claiming she's the devil and she will never die. Joel covers Ellie's mouth and they quietly sink away in the darkness.
If you want to rip something off, rip off the best living American Author, you chuckle fucks. Also everyone read Blood Meridian, you philistines.
It always is, isn't it?
EDIT:
Fuck, now I want a Blood Meridian horror game. Which I will never have. You made me sad.
