The game was originally being developed by a (now defunct) company called Heartland Enterprises
in Harrogate, North Yorkshire (UK) but they fell out with Interplay
who then pulled the plug and gave it to Tribal Dreams
instead. Heartland's version can be seen in the video here
(YouTube video link). This video uses Heartland's assets that had already been submitted to Interplay as a promo for the game itself, but by then Heartland was no longer trading since Interplay had stopped paying them.
The game came with a manual discussing each of the 'evil people' depicted in the game, along with bios and the period they lived in. The older ones anyway are probably just made up.
