AGF is a fly-around-and-shoot-at-everything-that's-moving game. You can choose between one of nine ships with different capabilities.
You can play AGF in Single Player Mode against the computer or via an IPX-network against up to 15 of your friends. We even managed to play it over the Internet with 2 people, but this is not really fun, it was a bit slow. But this was before the version 1.07 routines were implemented.
