Build turrets to shoot and destroy the incoming truck convoy as they pass through on a straight road. This game is pretty easy to play and understand. Use the buttons on the right corner of your screen to build defences. Information about the building will be displayed during the game. Pay attention to the messages on the top left corner of your screen. Resources needed to build defences will be displayed on the left bottom corner. Look out for your health bar because when it is down, you lose.
