The SEGA Saturn version of Quake was the first official console port released for Quake. It was designed by Lobotomy Software and released by Sega of America in North America on December 2, 1997. A PAL release soon followed. Unlike the later Nintendo 64 version, the Saturn version uses the Slavedriver engine, which as the name suggests, was developed to power the Sega Saturn game PowerSlave. Consequently, all of the Quake levels had to be totally reconstructed for the Saturn version, except for the four secret levels E1M8: Ziggurat Vertigo, E2M7: the Underearth, E3M7: the Haunted Halls, and E4M8: the Nameless City. These were eliminated altogether and replaced with the Saturn exclusive levels E1M8: Purgatorium, E2M7: Hell's Aerie, E3M7: the Coliseum, and E4M8: Watery Grave.
In addition to the four exclusive secret levels, the Saturn version includes an exclusive hazard, the Void, and an exclusive unlockable, "Dank & Scuz", which is a story set in the Quake milieu and presented in the form of a slide show with voice acting. It has no multiplayer modes, so all of the deathmatch maps from the PC version were removed.
