David Craddock, producer on the FPS Documentary and the author of previous video game history books like Dungeon Hacks and the Stay Awhile and Listen series about Blizzard, has launched a Kickstarter for a new series of videogame history books: Long Live Mortal Kombat.

Craddock is compiling interviews with developers who worked on the classic fighting game, as well as with fans and competitive players from various points in the series' lifespan to craft a three-part narrative history of Mortal Kombat. The first volume, The Fatalities and Fandom of the Arcade Era, is dedicated to the games' roots in arcades, as well as the early efforts to bring Mortal Kombat to home consoles and PCs.

David Craddock is the author of Long Live Mortal Kombat, as well as books about Diablo, X-COM, and other classic games.
