Air-Sea Battle is basically a target shooting game. On most settings, you are positioned at the bottom of the screen.
you shoot at targets at the top of the screen.
One of the nine Atari 2600 launch titles the various settings provide different targets and weapons with different characteristics.
There are six basic types of game available in Air-Sea Battle, and for each type, there are one or two groups of three games, for a total of twenty-seven game variants.
Within each group, variant one is the standard game, variant two features guided missiles which can be directed left or right after being fired, and variant three pits a single player (using the right gun) against a computer opponent, which simply fires continuously at the default angle or speed. In every game, players shoot targets (enemy planes or ships, shooting gallery targets, or each other, depending on the game chosen) competing to get a higher score.
Each round lasts two minutes and sixteen seconds; the player with the higher score after time expires is the winner, unless one player wins (and ends the game) by reaching 99 points before the time is up.
Each of the two player games is a matter of who can hit more targets in (oddly enough) 2 minutes and 16 seconds. (The manual says that the game will also end if one player hits 99 targets. I have yet to see this happen.) In each of the single player games, the single player tries to outscore a computer opponent that simply constantly fires.
