If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Join the military and transport some important cargo from one unit to the other. Your truck is fully loaded when you begin the game, and you have to make sure you take at least one box to the end. Be very careful how you drive, you have to keep your balance at all times in order not to crash or lose your load. Hurry up, because time is an important component to your score. Have a great time!
Use your arrow keys to drive.
