Harrier Attack II is the official sequel to Durell Software's Harrier Attack! The game consist of a unique blend of arcade, strategy, flight simulator and fighting game.

The action takes place on three colony islands which have been invaded by enemy aggressors. You play the roll of Harrier Jump-Jet pilot, of course, and have been dispatched on your aircraft carrier to help repel the invasion. Over a series of missions, based on the first two islands, your pilot gains extra equipment, weapons and skills. During these missions your Harrier is armed with infinite ammunition, but has limited fuel. As you win more and more awards the game is metamorphosed, until on the third island, the game is transformed into a totally different game. Here you must arm and fuel your Harrier, based on weight restrictions, take-off methods and the number of weapon attachments you have won. Using the new skills gained in the previous missions you finally vanquish the enemy from the third island.
