When it comes to flight sims the holy grail has always been the patched and systematically upgraded version of Falcon 4.0. Operation Infinite Resolve also features new missions and scenarios, and a new flyable aircraft, the A10 Warthog. Graphics take advantage of the power of contemporary video cards, offering higher resolutions, and the physics model and flight dynamics of all aircraft have been reevaluated and upgraded. G2 Interactive's enhanced version of the 1998 MicroProse flight combat sim Falcon 4.0 includes a number of new features and improvements designed to make use of new gaming technology developed over the years.
