Okay, questions I have about the demon dogs.
1. Can they be killed? The RPG, p'raps?
2. What happens if a dog attacks you while you're out of your car?
Maybe someone who has the game all set up can answer these questions, as I restarted my game file so my roomie could have a go.
1. Yes! Takes a lot of bullets. Best weapons are: grasscutter, RPG and assault rifle
2. Half of your health is lost and York falls down
