You are in the republic of Macedonia and have to protect the citizens from the UCK invaders. You are at the bottom of the screen and shall fire at the invaders moving at the top of the screen. For that purpose, use the left and right arrow keys of your keyboard to move, and the space bar to fire. Take care! Sporadically, innocent citizens will appear right above you. You shall not get them of course! Beside, take care that when the invaders are closer to you, they shoot at you. It is therefore better to try to get them when they are still far. To start the game, type a name in the field at the top then click the start button. Good luck.
