Source code for Lobotomy Software’s FPS game engine for Saturn: Slavedriver, uploaded online as open source code
In a rather unexpected move, the source code of the Slavedriver game engine, developed by Lobotomy Software for use with the games they developed for the Sega Saturn, has been uploaded to Github and the Internet Archive as open source code.
Lobotomy Software first used this engine to create their own original FPS game, Powerslave (Known as Exhumed in Europe), and used a modified version of the same engine to create the Saturn ports of Duke Nukem 3D and Quake, both legendary classic FPS titles for MS-DOS which ended up also being reputable games on Saturn. Lobotomy since closed their doors in 1999, so the group responsible for uploading the code from this engine goes by “Lobotomy Software Open Source Group” and consists of an unknown party. For what it’s worth, they claim to have the blessing of Ezra Dreisbach, who was the main programmer for Lobotomy’s 3 Saturn FPS titles and seems to have left the video game industry behind him after last being credited for the Xbox 360 port of Death Tank, a game he previously designed for Saturn and hid within Saturn copies of Powerslave and Duke Nukem 3D.
It’s important to stress that only the engine code has been uploaded online, and it’s the 1996 version of the engine that was used for Powerslave, not the amended version used on Duke Nukem 3D or Quake, which both came out the next year. None of the assets from any of those three games are included. The engine is available now under GNU General Public License 3.0, which basically allows anyone to look at, share, and modify the code to their heart’s content. You’re also allowed to share any modifications you make to it.
