Midway Games. This version was developed by the same programming team that worked on Doom 64, at id Software's request. The Nintendo 64 version was originally slated to be released in 1997, but Midway delayed it until March 1998 to give the team time to implement the deathmatch modes. Both console ports required compromises because of the limited CPU power and ROM storage space for levels. For example, the levels were rebuilt in the Saturn version in order to simplify the architecture, thereby reducing demands on the CPU. The Saturn version includes 28 of the 32 single-player levels from the original PC version of the game, though the secret levels, Ziggurat Vertigo (E1M8), The Underearth (E2M7), The Haunted Halls (E3M7), and The Nameless City (E4M8), were removed. Instead, it has four exclusive secret levels: Purgatorium, Hell's Aerie, The Coliseum, and Watery Grave. It also contains 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. There are no multiplayer modes in the Saturn version; as a result of this, all of the deathmatch maps from the PC version were removed from the Saturn port. The Nintendo 64 version includes 25 single-player levels from the PC version, though it is missing The Grisly Grotto (E1M4), The Installation (E2M1), The Ebon Fortress (E2M4), The Wind Tunnels (E3M5), The Sewage System (E4M1), and Hell's Atrium (E4M5) levels. It also does not use the hub "START" map where the player chooses a difficulty level and an episode; the difficulty level is chosen from a menu when starting the game, and all of the levels are played in sequential order from The Slipgate Complex (E1M1) to Shub Niggurath's Pit (END). The Nintendo 64 version, while lacking the cooperative multiplayer mode, includes two player deathmatch. All six of the deathmatch maps from the PC version are in the Nintendo 64 port, and an exclusive deathmatch level, The Court of Death, is also included. An unreleased Game Boy Advance port of Quake was in development from Randy Linden in 2002, and was pitched to id Software in that year. The port was rejected by the company, and Linden's work would remain unused until prototypes of his work were dumped in June 2022. Two homebrew ports of Quake for the Nintendo DS exist, QuakeDS and CQuake. Both run well; however, multiplayer
