The Chaos Engine was ported to the Archimedes by Visions of the Impossible

A time traveler visits Victorian England and helps Baron Fortesque to construct an artificial intelligence known as the Chaos Engine. However, the device rebells against it's creator and turns the country into a war zone populated by mad machines. Mercenaries are willing to enter this dangerous place and put an end to the chaos, hoping for an appropriate reward.

Chaos Engine is a run-and-gun overhead shooter with sixteen levels (in four groups of four). The basic gameplay is similar to Gauntlet, but in an open air setting, with bridges across rivers and other features in the maps.

There are six characters available in the game, each with different strengths and weaknesses, and different starting prices. In two-player mode each player chooses a character and plays co-operatively, but in one-player games the player also chooses a character for the computer to control, with its artificial intelligence allowing it to open doors, pick up power-ups and take on enemies away from the ones occupying the player-controlled character.
