A time traveler from the future was stranded in Victorian England, and his knowledge of yet unknown technological inventions was passed to the Royal Society, headed by Baron Fortesque. With the help of this knowledge, Fortesque managed to construct an immensely complex artificial intelligence known as the Chaos Engine. However, creation rebelled against its creator, assimilated its mind, and turned Britain 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 (Soldiers of Fortune in the US) is a run-and-gun overhead shooter. Sixteen levels (in four groups of four) await the players in the game. The basic gameplay is similar to Gauntlet, but in an open air setting, with bridges across rivers and other features in the maps. The visuals are in the 'metallic and blue' style Bitmap Brothers appeared to favor.

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.

Shortly after the game's release, Renegade took out a full page advert in trade magazine CTW, which simply said "The Chaos Engine. So good, even that bastard Stuart Campbell liked it", referring to a British journalist who had a habit of not liking much-hyped games, including previous Bitmap Brothers titles Xenon 2 and Gods, but gave this one a great review. Ironically Campbell later worked for CTW (as of 2004).


The original beta version (as seen on TV in many countries) was a three player game (not two).

German index

On March 31, 1995, The Chaos Engine was put on the infamous German index by the BPjS. For more information about what this means and to see a list of games sharing the same fate, take a look here: BPjS/BPjM indexed games.


A quote from the manual addendum lying in the game box:
Please note - In order to continue the time-honoured Bitmap Brothers tradition of mucking around with the password system at the last minute, The Chaos Engine now only awards passwords at the end of every world rather than after every Equipment Screen.


Version differences

  • In both the SNES and Genesis versions of the game which are named Soldiers of Fortune, the game's ending credits still call it The Chaos Engine.
  • In the console versions the Preacher was changed into a Scientist due to Sega and Nintendo having a policy of censoring any religious material in games for their consoles.
