Knock-Off! from Kenner (1969)

Released in 1969 from Kenner Knock-off was touted as a game of “fast, unpredictable action.” Operating on four D-batteries, the game challenged two to four players to be the first to knock-off an opponent’s “Fall Guy.” Each player controls two reverse-action switches that make a motorized mechanism, dubbed the “Big Bopper” move forward, backward, and swivel across the plastic playing field.
