Click the red Play button in the middle of the screen. Then click the Start button on the right side of the screen. You can then press the right arrow key to begin walking up the street. It will not take long for you to encounter the first wave of looters. Your goal is to stop them before they reach the electronics store and start stealing.
You can stop the rioters by pressing A to hit them with your stick and S to kick them. Depending on which option you choose, it will take between 4 and 6 hits before you are able to stop them. The good news is if one or more looters does manage to get past you, there will still be an opportunity for you to stop them once they grab what they want and begin walking back down the street.
ARROW KEYS: move
