Defender

Defender, released by Bally in February 1941, is an electro-mechanical gun game rather than a traditional roll-down pinball. For a nickel, players got 100 shots, and the backbox featured a mechanical animation of an airplane flying around — a novel attraction for the era.

Surviving trade press from The Billboard shows two versions of the game published a week apart, with differences in the backglass art, the art behind the animated airplane, and even the wood used for the gun-mounting board — suggesting the game went through quick revisions shortly after release.

Defender's aircraft-combat-and-warfare theme fits the period, arriving as world events increasingly shaped American amusements. Little is documented about its designer or broader reception, but as an early Bally gun game with mechanical animation, it stands as an interesting artifact of pre-war coin-operated entertainment.
