Iron Aces 2 starts off as a WWII combat flight simulation. Since the missile did not exist at that time, pilots were forced to lock into deadly, close-quarters combat. Using tactical maneuvers, pilots flew within 400m of the enemy and fired with heavy machine guns. As you progress through the game you will travel through the history of combat aviation. The numerous missions are based with conflicts involving land, sea and air campaigns.

Iron Aces 2 is broken into Campaigns and Missions. There are more than 35 missions that must be completed in order to finish the game. As you successfully complete each campaign you are advanced to a new mission as well as a new era. What gives this game an added dimension is the Free Battle Mode. This section of the game allows for the choice of opposing aircraft regardless of the era from which it originates. No other combat flight simulator currently available for PlayStation 2 allows you to fly, say, an FA18 Hornet against a P51 Mustang in air-to-air combat.
