ive now played the full version of the 'game', (the demo doesnt allow you to shoot).
its more of a simulation, so see what it would have been like to be the sniper and how the theory of the second gunman was wrong.
or you can try and do a mass murder and kill jfk, his wife and 3-4 secret service goons before they speed off.
its worth a play for novelty and educational values.
