Space Invaders is a very innovative and is one of the first shooting games featuring the defeat of alien forces. Thus, this gaming software has laid down inspiration for many games, which owes its origin to this version of Space Invaders.

This game is two dimensional, having only one player to control a laser based cannon to defeat the enemies. The player has to constantly move the cannon horizontally and keep shooting at the aliens. The aliens in the game are seen descending, and the player has to aim at them. The motto of the player is to shoot and defeat the aliens, and on defeating the enemies, the player is awarded with points. Defeating every wave of alien makes the game all the more difficult, and this series of invasion goes on without having an end.

The enemy also attempts to destroy the player’s laser cannon by shooting at it, when the aliens reach the bottom of the screen. The alien succeeds in their aim on being able to reach the bottom of the screen. A “mystery ship” occurs periodically, which helps the player to earn bonus points, on destructing it. The game is very interesting, and offers the player with various difficulties before they can win.
