I am wondering what the rescue vehicles will be in Left 4 Dead 2. They seem to have covered the basics already: helicopter, boat, plane, military personnel carrier. Accepting the premise that the survivors are circumventing waves of undead to escape the infection zone, there just aren't that many vehicles left that can do the job. What's next? A train? An eighteen wheeler? A bus? Call a taxi?
I don't know what they'll do, but I hope Valve doesn't try to rip off my bicycle idea. I thought of it first!
