Chaosium have released the 7th edition of Call of Cthulhu, the results of a recent Kickstarter campaign, in digital multiple formats. Unlike previous editions of the games, this version has ben broken into two books: a book for players called the Investigator Handbook and a book for the GM called the Keepers Handbook. The former is available now as a PDF from $22.95 from their store, as is the latter which costs $27.95. These same products have recently been released to backers of the Kickstarter.
The company has also released copies of the books in ebook formats including mobi, ePub, and strangely enough the less utilitarian PRC format at the same price as the PDFs.
