Grand Theft Auto: Vice City/Guardian Angels

This mission will be hard if it's your first time. Anyway, go to the parking garage in Vice City (Closer to Kent Rosenberg's office) Then, as you drive up the ramp, on the first floor, on your right you will see a gun. Take it. Then, you will meet Lance Vance. Get in his car and wait for him too. Then, go to the ally located on your map. Get out of your car, and walk up the right staircase. (Not where Lance Vance is) Then, take out your gun, or do a cheat for weapons, and step in the pink circle. You will see guys coming. DO NOT SHOOT THEM!!!! Then, shortly after that a red car will come. Shoot the red car and the other cars that keep on coming. Then, there will be a clip of two guys on dirtbikes. One will be shot. Take his dirtbike, and his gun, and go after the other guy. Do a drive by and kill him. Get off your bike, and collect the suitcase floating above him. (NOTE: The guy you shot may be lying about 7 feet from your bike.) Go back to Ricardo Diaz, and here will be a clip. After that, you will be informed you passed the mission. Wait until you get to any car, because you will receive a phone call from Ricardo Diaz.
