Practice your typing skills while defending the earth in this miniclip typing defense game. The earth is being bombarded with hundreds of asteroids. Your only hope is to type in the right coordinates of the unwanted foreign matters and blast them with your laser gun. You will see the earth in the middle of the screen and the asteroids will come at it in different directions. Each one has a word written below it. You only need to type in the letters to automatically point the laser gun and destroy the incoming boulder. Each successful hit earns you points. Try getting all the entry correct to get a perfect score. Your accuracy is measured and every backspace you make when an error is made will deduct a percentage of your total accuracy and score. Bonus points will also be given if the shield is intact after the game and all asteroids were destroyed. After finishing a level, the next one will soon commence. More will appear on screen and you need to make haste in typing. You can use a power item by typing slow which in turn decreases the speed of the targets. This miniclip game is perfect for improving one’s typing skills and is recommended for all ages.
