This is probably the closest thing to a Chaos Earth setting I have ever seen in a movie. Giant bugs from another dimension descend on modern civilization in a mist(D-Shift perhaps?). The inhabitants struggle to survive while trying to figure out why and how this happened. All you have to do is replace the military guys with NEMA soldiers and exchange falling ash for the mist(Or do both). This movie also shows how quickly scared and confused survivors can turn on each other. I recommend watching this before any Chaos Earth RPG session, just to get in the mood.
