We will release The GASLIGHT Compendium as a PDF download on 1 June via RPGNow. The document is 190 pages, color throughout. It includes full-color front and back cover images. See previous posts with sneak previews of the cover.
The release of the hardcover edition will be later in the month of June. The exact date is still to be determined. The book is at the printer, and we expect a proof in no more than two weeks.
The cost of the PDF version of the rules will be $30 USD. This represents a discount over the hardcover edition which will follow. We do not know the final hard-cover price yet.
