Space Invaders

Space Invaders is a very simple game by modern standards, but it was a technological marvel in its time. Typical levels consist of a player piloting a laser cannon to battle columns of descending aliens while using shields to block alien fire. The speed of the alien approach increases as the game progresses, adding to the tension. A bonus alien spaceship appears from time to time, which offers the player an opportunity to score additional points by blowing it up.
