The original PC game was updated with a corrected aircraft model once the F-117 Nighthawk was declassified and with 256-color VGA graphics instead of the original's 16-color EGA, among other changes. The new game introduced new theatres of warfare such as Cuba and Operation Desert Storm - in the wake of the Persian Gulf War, the Iraqis were no longer the allied nation that they had been in the previous game.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
