It's a post apocalyptic world. The city is destroyed and filled with nothing but hostile mutants. You, are one of the survivors. You're walking around the destroyed city, scavenging for supplies. Suddenly, you hear the sound of a bush rustling, followed by a weak voice of a girl.

"Ngh... Damnit..."

You head towards the sound, just to find a soldier girl, crawling on the ground, heavily injured.
