The first thing that strikes you when playing with Aces, is the simulation's realism. For example, if a plane comes to attack the ship, you will give orders to shoot it.
Strategy holds an important part in the game.
On the charts, you will plot the course of your ship to intercept convoys in the North Atlantic. Aces offers you a wide choice of single missions divided into three sections. Historical missions will place you in the same conditions experienced by captains in the past. The Convoy Encounter will let you customize the level of realism, select your type of U-Boat, set the meteorological conditions, and more, to provide you with good training. The last choice is the Warship Encounter, a serious challenge where you will have to battle against warships.
