You sit in the cockpit of the only fighter on board the earth supply ship. Your mission is to defend the mothership against the Cyclons.
You have instruments to give you up-to-the-minute reports on your shields, laser power and fuel. Directly above you is the long range radar to warn of aproaching fighters.
Once you have a cylon in view, you must line it up with your targeting computer and fire your laser with the space bar. When fuel runs low you may return to the rnorhership to refuel.
Complete instructions are given in the program. There is a choice of keys to suit left and right handed players and a joystick option.
There is also a pause facility to allow you to have a rest. The 3D graphics are brilliantly laid out, especially taking off and landing sequences.
