|2 Minutes||Get 30 kills|
|Get 10 headshots|
|Destroy 2 vehicles|
You will be using a Sawn-Off Shotgun for this. You have your usual grenades too so as always, use those to create fireworks via all the many vehicles that will appear. The hippies ride in on scooters, convertibles and bicycles so rain down fire on them. You can get a nice collection of vehicles going if you stay in the middle of the street.
The hipsters will come from either end of the street and funnel round shops and staircases so keep an eye on both directions. You should easily rack up the 30 kills for the gold medal because the shotgun can kill incredibly fast. Make sure to be quite near to the hipsters as the shotgun is not a good gun for long range.
The one challenge you may miss is the headshot challenge. 10 headshots with a shotgun is not the easiest feat. You must close the distance in order to line up the shot. Keep trying for headshots on almost every enemy anyway because doing so will fill your special meter, allowing you to stay alive. If all goes well, you should end up completing the challenges pretty easily.
