Pepsi Invaders is a reskin of Space Invaders that was privately commissioned by the Coca-Cola Company. According to legend, only 125 carts were made and distributed to various Coca-Cola executives, making it one of the rarest video games of all time. The main difference between this game and vanilla Space Invaders is that you can only shoot one bullet at time, as the trick to having two bullets on-screen at once doesn't work in this game.
Nevertheless, ShesChardcore manages to work around this disadvantage and complete a single level in record time.
