This is the built-in game for the APF MP-1000 videogame system released in 1978. The object of the game is to destroy the most space ships within 1 minute period. In 1 player mode (see video below), your opponent is the videogame system. For the first minute it will fire at the space ships trying to score most points. Then, it's your turn, also for 1 minute. The player has an advantage over the system, as he can move the firing station from left to right along the bottom of the screen. It was inspired by the Atari arcade game Anti-Aircraft (1975)
