The player takes control over a space ship who has to destroy aliens which want to conquer earth. Similar to Space Invaders the player is glued to the lower side of the screen and can only move left and right. In every of the 20 levels he has to kill all aliens which either move towards him from the top side of the screen or come in from the sides. While doing so he has to avoid the shots of the enemies - if he doesn't he gets killed after one hit and loses a life. Sometimes he has the possibility to collect one of the following power-ups: an additional life, extra points, faster shots, double shot or enemy freeze. |
