Anirog's version of Scramble is remarkably similar to the version found in the arcades.
The game consists of various landscapes and cities scrolling from the right to the left of the screen. On the ground are various missiles, fuel dumps, rockets, etc - you gain points if you can blow these up.
Depending on which landscape you are flying over, rockets may take off or UFOs and fireballs may attack you.
The graphics are slightly on the slow side and rather jerky, though after playing a few times you do get used to this.
The colours and definition used in the graphics are top quality and cannot be criticised.
The sound is quite good too, although I would have liked a firing noise to be made when I press the fire button - the only fault here.
The program can only be used with a joystick - perhaps this is better than bashing your keyboard to pieces! The fire button releases both missiles and bombs when pressed.
