Combat Pilot is a self-contained online multiplayer simulation built on the Microsoft Flight Simulator X (FSX) engine. As a result, FSX (sold separately) is required to be installed on your machine to fly in Combat Pilot. The planes, airports and missions found in FSX are completely separate from Combat Pilot. Combat Pilot is focused on combat aviation and utilizes its own aircraft, bases and missions.
Below is a summary of FSX. For more information on FSX, visit http://www.microsoft.com/games/flightsimulatorx/
Microsoft® Flight Simulator X immerses you in a beautifully rich and realistic world with dozens of aircraft and interactive Missions for a completely new and innovative gaming experience. Free Flight lets you fly anywhere in the world, from your hometown airport to the most exotic places you’ve ever dreamed of.
Flight Simulator Gold Edition includes the Deluxe Edition and the Acceleration Expansion Pack in one bundle. In addition to all of the content in the Deluxe Edition, the Acceleration Expansion Pack delivers non-combat missions and enhanced DX10 graphics. Also included is an important service pack for Flight Simulator X, which improves overall game performance.
