In this 4 map L4D2 campaign, the city is burning. As ash falls, the survivors attempt to flee to a small military airfield on the other side of the river. It's a straight path down the main boulevard, but nothing is ever simple. Crashed cars, blazing fires, police barricades, and the zombies all stand in their way. This map can be played in Survival, Scavenge, Co-op, or Versus modes.
