Trivia
It is actually possible to perform a barrel roll in ANY of the helicopters in the game, given sufficient altitude, even the Blackhawk.
In the main menu (base screen), have you tried to click on the electrical outlet? (it sparks)
There are animals in each of the theaters (camels in Persian Gulf, Penguins in Antartica, and so on), and you can shoot the animals (indeed, splatter them with rockets should you choose to) UNLESS you're using the German version. In the German version the animals are invincible.
There is an expansion pack to Gunship 2000 titled "Islands and Ice". It adds two more theaters: Phillipines, and Antartica, and adds one map each to the existing Central Europe and Persian Gulf theaters. It also adds a mission builder for you to make your own missions.
When you first start the campaign, your rank, Warrant Officer 2nd, only entitles you to a single chopper. You have to make it all the way up to 2nd Lieutenant to command multiple choppers in a single mission.
Look for various "advertising signs" that you can destroy through the different areas. They advertise other MicroProse games, and you actually get points for destroying them!
Gunship 2000 is the first game where you can pilot a chopper and fly through a train tunnel... Long before the final scene in Mission: Impossible the movie.
If you click on the "monitor" in the main menu section (inside the base office), the screen will switch among three modes, one of them is pong, one is gunship, and third is some document...
