A way cool branch off of the Cyberpunk style is Steampunk. Take that gritty attitude and style, but place it at the end of the 19th Century instead of the early 21st. Steam powered Babbage Engines clanking out computations. Stout hearted heros (and heroines) with large Webley revolvers. The very latest in Science saving the day.
