The Chaos Engine is a two-player cooperative top-down shooter set in a steampunk Victorian-era England. The game was developed by The Bitmap Brothers and published by Renegade Software in 1993 for the Amiga, both ECS, and AGA. Later, it was ported to Atari ST, SNES, Sega Mega Drive, DOS, and other platforms. In the US, it was renamed Soldiers of Fortune.
In the game, you can choose 2 of the six available mercenaries; one will be controlled by you and the other one by the computer, unless you have a friend with you. You will have to explore the levels, fight the enemies, find keys and power-ups until you finally defeat the Baron Fortesque and the Chaos Engine itself.
William Gibson and Bruce Sterling's novel, The Difference Engine, inspired the plot and settings. GamesNostalgia offers you the Amiga AGA version.
The sequel, The Chaos Engine 2, was released in 1996 and introduced a competitive mode instead of the cooperative one.
