Alien Invaders - Plus! is a game for the Magnavox Odyssey 2 that looks like a clone of Space Invaders. The key differences are that you don't have to destroy everything to win a level, just the red aliens, and that you can take one more hit once your spaceship is destroyed and use that time to convert one of the shield blocks into a another spaceship.
In this run, ShesChardcore and Memory shoot only their required targets with pinpoint precision, even taking hits and converting shield blocks into spaceships in order to get a better aim at the aliens.
