The Fall of Atlantis

The Fall of Atlantis is a top-down shooter game, a sequel to Project: Atlantis. Three years after the original game, the enemy ships return and once again threaten the underwater city of Atlantis. The player, swimming around in a military submarine, performs a series of missions set in fairly large levels, most of which involve combat against enemy ships.

The submarine can be turned with the arrow keys and moved forward by the A key, and it can shoot two kinds of weapons which are effective against different threats.
