Pilot your spacecraft in four dimensions as you battle your way back in time to free the universe from aliens by destroy-ing their planet.
In this machine code game your screen puts you in the pilot's seat so you can see the alien ships swooping towards you and in-dicators showing the state of your fighter.
Every so often you have to land on a friendly planet for fuel and repairs.
To reach the alien planet you have to spot random time-gates which whisk you back through time. And all the action is accompanied by 'realistic' sound effects. For more fun use a joystick.
Time-Gate comes with a program to show you how to use the keyboard controls, well-written inlay notes and a keyboard overlay.
