Hellcats over the Pacific is a flight simulator computer game for the Macintosh computer. It was written by Parsoft Interactive and released by Graphic Simulations in 1991. Hellcats was a major release for the Mac platform, one of the first 3D games to be able to drive a 640 x 480 x 8-bit display at reasonable frame rates in an era when the PC clone's VGA at 320 x 240 x 4-bit was the standard. The graphics engine was combined with a simple Mac interface, a set of randomized missions and a number of technical features that greatly enhanced the game's playability and made it a lasting favorite into the mid-1990s. The original game was followed with a missions disk, Hellcats: Missions at Leyte Gulf, which greatly increased the visual detail and added many more objects to the game.
