Invaders Revenge

As the last space invader, your mission is to destroy the human ships that prowl the space lanes. The human laser base fires at you with deadly accuracy.

The player controls a space invader which can move in all directions, and tries to destroy the human vessel moving at the bottom of the screen. The player has limited shots to make their kill, and must avoid other horizontally moving alien vessels. The player starts with 3 invaders, and can set the game speed and number of shots available.
