Pepsi Invaders by Atari inc on and Coca-Cola on the Atari 2600

A reskin of the system's version of Space Invaders, the player is tasked with shooting down a formation of letters spelling P E P S I which descend towards the surface that the player's weapon moves along.

Pepsi Invaders was commissioned by The Coca-Cola Company to be handed out to salespeople at their 1983 sales convention. Pepsi Invaders is one of the rarest games for the Atari 2600, with only 125 copies distributed.

The game is a modification of Space Invaders, with nearly identical gameplay, but with a number of tweaks. Instead of having limited lives and no time limit as in the original, Pepsi Invaders has unlimited lives and a three-minute time limit to complete as many levels as possible. If any invaders successful traverse the lowest row, instead of the formation dropping to the ground and ending the game, it merely moves left and right until all the lowest row invaders are destroyed. It is therefore impossible to lose the game.

Primary graphic changes affected the invaders, each row of which consists of the letters P E P S I followed by a single alien, instead of the original six aliens per row.[2] The letters move up and down as they march but do not otherwise animate. The UFO was changed to look like a flattened Pepsi logo in brand colors. A timer was added, displayed on the ground, which itself has been changed to a Coca-Cola like brown color.[3] An additional band of the same color frames the score at the top, with the word COKE prominently displayed to the left of the score. The player cannon now features two bands of the same brown color.

During the last 10 seconds, the timer and cannon limit indicators blink. When the time runs out, all invaders and UFOs disappear, the score changes to the word "WINS" (thus making the row read "COKE WINS!", and the player cannon and all texts and the player cannon flash rapidly. The player's final score can be seen in the attract mode after the game ends.
