Terrible game. You need to play it with a really fast mouse, something non-existing at the time this game was made (1988). It's a bit easier if you memorize the patterns of the enemies and when they hurt you. Sometimes you will see enemy soldiers shooting at you and you won't get hurt. Some tanks in the game also doesn't shoot.

The game have sort of an ending. It ends abruptly with game over message on the screen. But, watch the flag in the top right corner. The enemy surrenders.
