Explore the universe, destroy all Klingons before stardate 2000. Left & right arrows to turn, up arrow to move forwards, space to fire, S to put shields up (uses energy), X to lower them. You can refuel and get repairs at starbases (circles with spokes) so remember their co-ordinates! If you run out of energy or status gets to 0 you lose. Your position is shown top left - the universe goes from -1000 to +1000 in each direction. Study the behaviour of Klingons to win!
Loosely inspired by the classic Star Trek game on the Commodore PET in the late 1970s. No long-range radar in this version, I'm afraid, you just have to keep looking. There's nothing to stop you going into empty space but it's lonely out there! Thank you to my son Henry for doing some maths for me to work out what to change the X and Y offsets to depending on the ship's bearing.
