Atlantis , a classic action-adventure game for the Magnavox Odyssey 2, drops players into the midst of an epic battle to save the lost city from invaders. With hordes of Gorgon vessels swooping in from the skies, it's up to the player to defend the city's command posts and take out the enemy craft before they can wreak havoc on Atlantis' structures.
Gameplay involves controlling the command posts at the edges of the city, using whatever firepower is available to blast the incoming enemy vessels. As the game progresses, the Gorgon craft become increasingly aggressive, diving lower and faster as time goes on. If an enemy manages to get too close to the ground before being destroyed, it will unleash its deadly weapons, taking out a building in the city. With each passing wave, the stakes grow higher, culminating in a final showdown that will leave only one thing standing: can you save Atlantis from destruction?
