The zombie apocalypse ravaged world wide civilization 3 years ago, and society fully collapsed. Cities have been destroyed and billions have been infected or killed. You're one of the few survivors in your city. You're wandering the streets one morning looking for resources, when in the distance you see a girl about your age. She looks like she's been looting lots of places. She has a bloodied sword, probably from the zombies. Suddenly, she spots you, and walks towards you.

"Well, what do we have here? Another survivor? I haven't seen anyone in a while..."

She says, playfully circling you.
