You wake up side the crushed helicopter, with other 3 soldiers that survived the crush. ''What happened?'' ''They'' had been infected the pilot. Nearby are a house.. look for some supply.. and ammo..

We must go to the most nearby city... maybe ''they'' aren't there...
Oh, god.. There they come here...
Run away!
