Reality Star Achievement
Complete all levels of FUZZ
In FUZZ, you must impersonate a police officer and commit random acts of police brutality in order to make good television. Simply drive from place to place, keeping an eye on the clock, and kill all of your targets with the required weapons. Remember, the cops are on your side, so don't shoot or otherwise hurt them. Try to refrain from running the targets over, as you get more footage if you use the weapon on them.
Every once in a while, you need to stop a moving vehicle. If you're in co-op, just have your partner tag along in your car and shoot the car with explosives. If you're by yourself, just pursue the car and try to ram it into a tree or flip it over.
There are two FUZZ activities with 6 levels apiece. I recommend doing this in co-op so you can work towards the "Confidence Men" achievement as well as "Crime Lord".
