As the name suggests all that you need to do is shoot at the monster. The instructions are as follows. 1. Hit the play button to start the game. 2. The monster is protected by two boundary walls with partial openings revolving around it. 3. Press the right arrow or left arrow keys to move the spaceship around the monster. 4. Hit the space button to make the spaceship shoot bullets. The aim is to get through the boundary walls and hit the monster. 5. The monster has 10 lives and will die only after being shot 10 times. ENJOY!
