What would you do?

Would use a crow bar, I'd fine a secure location to camp in, unless my family died or something, I'd go out and kill, moving from spot to spot.

 

I would try first of all to watch the news to get a little bit more of information and then lock all my doors and windows, get my 9mm and sit in a corner waiting for those bastards to get in, and i would probably try to talk to my familiars via the phone to say goodbye
