At midnight on the 10th of December 1993, a small indie game development team called id Software uploaded the shareware version of their latest game to the University of Wisconsin's FTP server. That game, a little title called Doom, changed the industry forever. Often regarded as one of the best and most important video games ever created, and certainly one of the most playable. While not the first ever FPS, it was the game that popularised the genre before the term FPS even existed. The dawn of the Doom clone had begun. 30 years later and Doom is still as important as ever and over those three decades, a franchise was born. More games, sequels, spin-offs and reboots. Novels, a comic book and board games. Films, books and so much more. The Doom legacy. This book, Knee-Deep In Wads And Gibs: 30 Years Of Doom captures that 30 year legacy on the page. From the early days of id Software, the development of Doom and Tom Hall's famed Doom bible to the game's release and its impact. The massive Doom community, the modding scene and the fans. Controversies surrounding Doom, all of the console ports and some of the horror stories behind them being made... even a not-very-good (unfinished) Doom story scribed by me back in 1996 and so much more. A celebration of Doom, its fans and its 30 year legacy. Rip and tear!
