Introduction shot: one of those tram things is driving out of a burning city in the rain while military jets fly overhead bombing the lower districts and military vehicles evacuate along with the tram. You were being evacuated by the police on an electric tram when the power goes out, and you crash. Many of the passengers are hurt: this is where one of the survivors helps you get back up, and gets you to pick up an item and help some of the survivors. Zombies begin to appear along the track that you were just on. In the distance you can see the jets turning back around from the burning city and coming closer to the track. It becomes obvious that the tram is about to be bombed, so you have to crawl/jump out of the tram after one of the survivors hands you a gun. You run out of the tram, shoot some zombies, and then make your way into the forest.
that would actually be really cool to see
and then somewhere in pine ridge you can find a crashed tram with a bunch of craters along the track
