You're running as fast as you can. A huge hoard of infected is behind you, and they're fast. You keep running through the woods, but then...

CRASH!!

You trip over a large root. You try to stand back up, but your foot is stuck. The hoard is coming fast. One of them is on top of you now. You try to push him off, but you can't. You're just about to scream for help until...

BANG!! BANG!! BANG!!

Someone shot the infected on top of you. You look up and see your best friend, Ellie.
