Best Flash movie EVER made on Newgrounds.
Q: Why is the city like this?
A: It was hit by a nuclear bomb, much like every other large city in the United States and in several other countries across the world.
Q: Why did this woman go there?
A: To search for food, water, oil, weapons, or any other resources she can find in the city. (I realize this wasn't covered in the teaser, but keep in mind, it's just a teaser)
Q: What are these men in gas masks doing?
A: Like the main character, the soldiers were searching for any supplies they could find. They just happened to find the wrong person's ammo stash.
Q: Why do visitors get shot at on sight?
A: There aren't nearly enough leftover supplies for all the survivors (as is the case everywhere else in the United States, where anybody is left alive), so everyone is fighting for control of the few supplies they can find.
Q: How does a simple car locking device trigger a bomb?
A: Just like a car locking device can be wired to activate the power locks, turn on an alarm, or even start the car's engine, so too could it be rewired to activate a remote detonation device.
Q: What year is it?
A: I haven't decided on a specific date for this particular episode, but the nuclear attack happened in 2011 and this teaser is taking place roughly 15-20 years afterward.
Q: Who is this woman?
A: Her name is Sera, and she is a survivor of the apocalypse who is trying to survive in the wasteland.
