one of the best 2600 launch titles! this game is best played with a friend, with each player controlling a turret and firing at various boats, planes, and military vehicles. it can get pretty frantic, but i feel like dividing the visuals into clear rows and placing the player on a fixed segment of the screen makes it easy to understand what's going on. there's a real wealth of alternate gameplay modes here, too - you can play as a ship, firing at planes flying above you, as a plane dropping bombs on the ships below, etc. atlantis and missile command would later improve on what air-sea battle is doing here, but for the time it was released, this is really fun.
