Pepsi Invaders is a parody of the video game Space Invaders, designed by Christopher Omarzu for the Coco-Cola company, and given to visiting executives at the 1983 Coca-Cola sales Convention.
Pepsi Invaders is a game for the Atari 2600, and is redesigned so that you shoot the letters "P E P S I", instead of regular space invaders. Because Pepsi Invaders was made specifically for the Coca-Cola company, it was not given a store release. There were only 125 copies of Pepsi Invaders created, and they are considered incredibly rare being appraised at over $2,000 as of 2012.
