Cytron is a top-down sci-fi shooter created by Lunatic and published by Psygnosis exclusively for the Amiga in 1992.
Designed and programmed by Martin Hall and James Thomas, this title will remind you of Gauntlet, or, even better, Robotron: 2084 (whose name has probably inspired the creators). The main character is a small robot that will have to find its way across the maze-like levels, trying to destroy enemies and rescue the trapped scientists - yes, the plot has some similarities with D/Generation.
The robot can also split into two independent parts (called "Cyt" and "Ron"), that you can control with the mouse and joysticks. This creates interesting gameplay solutions since you will have to use the different characteristics of the two units to solve puzzles. Because of this, we can also add Head Over Heels to the list of references.
Some people are very fond of this game, which can be quite addictive. The only problem is sometimes you have the impression to play an 8-bit game, despite the high-quality graphics and music. This was probably the main problem of Cytron, which could have been a success if released a few years before.
