I was doing some bounty hunting in my viper and in the middle of a fight my shields went from near full to offline. What weapon does that and how do I avoid it? I got no you are under attack or a missle was launched at you just shields are offline. I had taken a few hits but was evading at the time and had popped a chaff. Do missles give a launch warning or is it best to always have a point defense installed or ecm?
