The backstory of Atlantis II (from AtariAge)…
 
“Defend Atlantis” was a contest from Imagic where contestants were invited to send in their high score along with a photograph of the TV screen showing the score, and an Atlantis proof-of-purchase seal from the instruction manual. The four individuals with the highest scores would be invited to compete in the Great Defend Atlantis Shoot-Off on November 14, 1982 in Bermuda.
Unfortunately for Imagic, there were a lot of good Atlantis players. In fact, more than four individuals maxed out the score, so Imagic had to figure out a way to decide who the top four would be. They created a special contest version of Atlantis, that they called Atlantis II, that these top scorers would use for a tie-breaker. Atlantis II is basically the same as Atlantis, except that it's faster, harder, and lower scoring.  The only graphical difference that can be detected is the font used for the score. This does at least make it easy to identify immediately upon turning on the game.
The game was sent to contestants in a standard Atlantis "Night Scene" box with a white sticker on it that says "Atlantis II". The cartridge itself is a standard Atlantis "Night Scene" label.  It is said that only 93 copies of this game were made.
