Air-Sea Battle

There are six basic game types 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 that can be steered left or right after firing, and variant three pits a single player (with the correct gun) against a computer opponent who simply fires continuously at the specified angle or speed. In each game, players shoot at targets (enemy planes or ships, shooting gallery targets, or each other, depending on the game chosen) and compete for a higher score. Each round lasts two minutes and sixteen seconds; the player with the higher score after time expires is the winner, unless a player wins (and ends the game) by scoring 99 points before time runs out.
