Dracula in London
This version of Dracula in London does not tell you what any of the sacred weapons or equipment do. It also omitted the game's prologue and vampire lore which provided hints as to what was going on. In order to get this information you were supposed to send money to Steven Jones (it was, after all, shareware). However this information was also provided in the original shareware DOS release as part of the program itself.
Information not included in either release was how the scores were calculated for each individual hunter, and the game mechanics. This was available from the author for a small cash contribution. A contribution would also give you music and sound effects for the Windows version.
Trivia contributed by Alan Chan, Patrick Bregger.
