Pros
L4D1 survivors.
Good variety and amount of items.
Different type of areas to hold out at.
Area has the classic feel of the first Left 4 Dead.
Provides nice challenge.
Radio.
Cons
Could maybe be opened up a bit more / breathing room.
This was a really nice map, with good detail to it.
I feel based on its overall appearance, it may be a little misleading and could be opened up a bit more.
Perhaps make use of the crashed plane and/or the train and/or the building with the graffiti on it.
Good potential for this map, I hope you keep it updated if you get any more ideas!
