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

Just run 'pyspacewar' and play. There is no need to build or install anything (although if you wish to do so, you can use the traditional 'python setup.py install').
