Vice City Media Attention Levels

On your stats page you will notice a stat called 'Media Attention Level'. This refers to the highest level of media attention you got in one 'killing spree'.
One good way of getting this up really high is to go on a huge rampage; killing cops, the army and pretty much everything you come across. However, a much easier, albeit less fun way, is to get a minigun (when you have infinite ammo) and to hold down the shoot button and aim it at a tank, holding it down long enough will cause your level to skyrocket and you'll soon be at the highest it can get.
