The screen displays the number of paratroopers left, the highest score achieved, and the score of the current game. There are multiple levels in this game. As you complete one level you move up to the next, more difficult level. The number of paratroopers increases as well as the speed at which they are dropped. The developer might want to configure the next version of the game so that Pocket PC users can press the action button to shoot.
Sabotage is intuitive and easy to use.
Don't worry too much. You have seven lives and can choose from three types of Metalion, each having different weapons. Still, the bad guys come at you fast and furious. You have to keep your finger on the trigger and your eyes open. In really bad situations you can use the special Super Bomb, but use it sparingly.
