In issue 71 of Your Sinclair magazine in November 1991, this game was voted the 51st best game of all time.
The game takes place in 1997 (the same year as RoboCop (1987)) and 2084 the same year as Total Recall (1990). Both films were directed by Paul Verhoeven, and Arold Schwarzenegger was considered for the title role in t he former. 1997 is also the same year that Lost in Space (1965) & Predator 2 (1990) take place.
The arcade version's eight-directional dual-joystick control scheme (one to move, one to fire) was implemented when the game's creator, Eugene Jarvis, had his injured right hand in a cast. He was unable to play the arcade game Berzerk, because the cast prevented him from pressing the fire button. The two joysticks made it possible to move and fire at the same time without having to use buttons.
