I'm trying to track down a game I used to play with my friends.
It was a two player game that all took place on a single screen. In the centre of the screen was a sun, and you both had control of a ship in orbit. Bullets fired were all subject to the gravitational pull of the sun, as was your ship. I think the controls were the standard push to go forward, left and right to rotate. I think there was also an option you could select where pulling back would teleport you to a random location on screen. It was a PD/shareware game, given away on a coverdisk, but I can't remember either the magazine or the game name.
It was essentially the close combat part of Star Control.
