Spoiler alert.......This achievement is unlocked through the Last of Us DLC ‘Left Behind’. The brick throwing contest itself is a part of the main storyline within this DLC and can’t be missed. You will come to a section within the mall whereby Riley challenges you to a brick throwing contest at these two (2) cars located on the lower level. You both have identical cars (one is blue and one is red) and you simply have to smash all the windows of your car before she does. There will be a couple of windows on the side you start on, then you will have to work your way around the balcony to reach the windows on the other side, there are a few on the side, back, front and top of the car. The bricks themselves are scattered sporadically along the balcony but are easy to spot. You throw the brick exactly like you normally would and you simply just ha e to smash the windows quicker than Riley and then the achievement will pop.
