A-10 Attack! is a combat flight simulator for the Apple Macintosh computer released by Parsoft Interactive in 1995. The game features an A-10 Thunderbolt II aircraft that takes part in a variety of missions in West Germany during a hypothetical limited conventional attack by the Warsaw Pact. A-10 boasted one of the most detailed flight models of any game of its era, a physics model that extended to solid-body interactions with the ground and complete aerodynamics for every object in the game, including ordinance.
The game was followed by a sequel named A-10 Cuba!, originally as a stand-alone game on the Mac and Windows-based PC's, but later re-released on the Mac as a plug-in module for the original game. The Mac OS versions were produced by Parsoft, while the PC version of Cuba was a joint production with Activision.
