The year is 2056 and SDI has finally been switched on. It works pretty well. On the night before Christmas, a friendly bunch of aliens decided to take over the Star Wars technology and turn it against the Earth as a weapon. So, what does the Earth do? They send an anti-aircraft plane. Fine, and guess who's flying it?
Controls are standard left/right/up/down/fire and all you have to do is fly over a rotating globe, shooting the aliens. This isn't easy because the aliens move fast and you don't. Also, when you turn, your view doesn't change. Talk about cutting corners.
