Why does it matter?
Not like these games had a story line :|[/disappointment]
BFLZ go to the Hospital and get saved by the Helicopter
The Pilot fails to warn them that he got bit by a zombie, Zoey thus shoots him
The Helicopter crashes near Riverside, (Death Toll campaign location) que Crash Course opening
They go to the park and the resuce boat saves them, you can see Newburg (Dead Air location) across the horizon
They thus go to the Airport and go in the plane, which possibly runs out of gas and they land near the Blood Harvest location in Pennsylvania, where the Military saves them in their APC, YOU FINISHED ALL THE CAMPAIGNS :3
