The first thing to know when you're learning how to type is proper finger positioning on the keyboard. If all the buildings in your city are destroyed, it's game over.
If you fail to type the word, or type it too slowly, the alien will damage one of the buildings in your city. If you type it correctly, a laser will destroy the alien. As the aliens descend from the top of the game screen, type what you see above the alien in lowercase or uppercase. Typing Aliens is a free online typing game available on the BattleLine Games LLC.
