About Atlantis Ii
Imagic's Atlantis, designed by Dennis Koble and released in 1982, came with a high score contest: the top four scorers would win a trip to Bermuda. Atlantis II is the special cartridge tied to that contest, a harder version that Imagic gave to its winners. It shares the box and cartridge art of the original, distinguished only by a white Atlantis II sticker, which makes genuine copies a prized collector's find.
The gameplay is the same as Atlantis. Waves of Gorgon ships pass over the undersea city, and you defend it from three fixed gun posts on the left, center and right, choosing which one fires by the direction you push. Ships that dip low enough fire on the city's installations, and once every one of them is destroyed the game ends. The difference is in the tuning: enemy ships move noticeably faster and are worth fewer points, so building a high score takes much more effort.
Tips for Atlantis II
The side guns fire diagonally and the center fires straight up, so learn which gun reaches each altitude.
Destroy ships while they are still high on the screen; once they drop to the lowest pass they start hitting the city.
Points come slower than in Atlantis, so concentrate on survival rather than greedy shots.
