Small and unobstrusive, the invaders are definitely coming. Street art in London incorporates a myriad of themes of which early computer game characters are just one. Like PacMan, the Space Invader reminds us of less complex times when Atari game programmes were the daddy, only two dimensions existed and the graphics were formed along classic lines.

Space Invaders is a simple game. Aliens are about to invade your planet, and you have to blast them before they can land. You have a blaster and three lives to shoot them down as they slowly advance downward one at a time, while also shooting at you. As the invaders thin out, they start moving faster. Occasionally, a UFO flies by that you can hit for bonus points. You also have three shields in the air to protect you, but as they take fire, they slowly erode. The game has an infinite number of levels, and ends if either you lose all three lives or if the Invaders reach the surface.

Game Over.
