Invaders

Invaders is a single-player electromechanical machine from Genco Manufacturing Co., manufactured in October 1953. It is listed as flipperless and uses mechanical reel displays for scoring, in keeping with the early-1950s amusement games Genco produced.

All of its play and scoring was handled by relays and stepper units. This is an obscure early-EM title with limited surviving documentation; the record comes from the Pinside machine database and is not yet cataloged on the Internet Pinball Database.
