Gunship is one of the many games that first appeared as a PC game, and then was ported to the PlayStation. Pretty good deal, I'd say. Gunship is a flight simulator that puts you in the cockpit of a small variety of U.S. combat helicopters. Not being a helicopter pilot, I can't vouch for the verisimilitude of the flying, but the game is absorbing. Although I'm guessing it's easier than piloting a real chopper, Gunship is far more difficult than the average PlayStation game.
Combat takes place in two theaters of war, Europe and the Persian Gulf.
As you might guess, Europe is hilly and green, while the Persian Gulf is flat and brown. There are a plethora of enemies and, even in the first few missions, almost a bewildering array of tanks, anti-aircraft guns, enemy helicopters, and assorted collections of numbers and letters that I didn't recognize, but that shot at me nonetheless. Missions typically consist of a primary objective that must be destroyed, with secondary targets that are somewhat optional. Unlike most arcade oriented combat sims, where targets tend to be stationary, the mission objectives in Gunship are more realistic mobile targets like a convoy of trucks or a tank squadron. The graphics are less impressive than on the PC, but are slightly better than Warhawk or most of the other PlayStation sims I've seen.
