This prototype was never released (6 units are known to exist). If this game had been released on schedule it would have commemorated Atari's 20th anniversary. It has 2 games on offer, "Super Centipede" and Missile Command II. They are both re-makes of the original classics but with enhanced graphics and sound.
After selecting "more new stuff" in the operator's mode; two kinds of spaceships will appear in the Missile Command II game. The Mothership that appears after a few levels is exactly the same as (except less detailed than) "Birdsnest", which is a spaceship on page 21 of the 1978 book "Spacecraft 2000 to 2100AD".
The spaceships in the "Invasion Wave" are probably ripped from another book in the series.
