You wake up on a rooftop in the city of Allegheny, an infection has destroyed the populace of Pittsburgh and the surrounding area. A note from a soldier says that a pilot is picking up survivors on top of mercy hospital. First aid kits are around, as well as an ammo stash. There are no weapons around, but you being resourceful, brought your own. As you survey the broken city mobs of what used to be people roam aimlessly, the sky is overcast and as you look up, it starts to drizzle. You have a choice, stay in the city and pray for the government to send help, not likely, or take matters into your own hands and join the one who left the note.
