3 Two ships duel in a gravity field. Gravity doesn't affect
4 the ships themselves (which have spanking new anti-gravity
5 devices), but it affects missiles launced by the ships.
7 You can play against the computer, or two players can play
8 with one keyboard. There is also a Gravity Wars mode, where
9 the two ships do not move, and the players repeatedly
10 specify the direction and velocity of their missiles.
