Quake has hundreds of user created levels - known variously as "mods", "total conversions" or simply "maps". To run new maps, place the bsp file into the "quake/id1/maps" subdirectory, and start Quake with the +map MAPNAME option.
Installing mods is simply a matter of creating a subdirectory DIR and extracting the contents of the mod zipfile/tarball into this directory. It is then loaded by using the -game DIR command line option and, sometimes, +map MAPNAME where MAPNAME is the mod's start map.
For both maps and mods, all files should be in lowercase.
There has recently been an effort to archive many Quake maps: Quaddicted maps, mods.
Some of the more notable mods:
This recently released mod is a must have. It includes 15 single player levels, stunning bosses, and a couple of twisting spider infested caverns. Distrans has also contributed a professional quality soundtrack, composed of moody and interesting electronic vibes. Link
Gorgeous medieval themed mod with two single player episodes, a melee style arena mode and nice documentation. Many thanks to Tronwyn, Fat Controller and their co-authors. Link
Quoth began life as a sequel to the (draw-dropping) mod, Contract Revoked, but has recently gained much support from mappers, as is becoming the defacto extension of Quake I.
It's new features include numerous crazy enemies (with better AI), destructable environments, and other items including ladders and flashlights. Link
Epic. Ambitious. Otherwordly. Nehahra is the definitive Quake mod, supported in Linux by LordHavoc's Darkplaces, and QuDos' port of the NehQuake engine. It has some great models and maps, uses fog effects well, and has an (optional) two hour movie/demo which ties-in well with the original Quake "story-line" but is also in desperate need of an edit.
Nehahra also features improved enemy AI - the grunts strafe behind cover, and scrags in open space can be very hard to pin down. New gamers may wish to disable this feature by typing nomonsters 1 at the game console. Link
Dark and bloody, with Doom's paranoiac atmosphere. A classic. Zerstörer also has some good death match levels - Link
Neil wrote the definitive Half-Life mod "They Hunger". The quality and fun is in these maps too - alba01, alba02, sofsp1, sofsp2, starshp2, Link
Oum is one of the few Quake 1 mods with a sci-fi feel. It has five well made levels, with cut-scenes and many new weapons - Download, Link
SdS is a speed run through Mission Pack 1, Scourge of Armagon. Hilarious and amazing. Link
Cracking game-play and rivers of blood - Link
FQ is a traditional medieval themed conversion. The game has some beautiful levels, but also plenty of raw edges as it was never quite finished. (The project ended prematurely when the web hosting hit a snag). Not all the player classes work perfectly. Use the "g" key twice to purchase items, the "<",">","/" keys for inventory, and the "w","e","r" keys for the grappling hook - Manual, Link
Scourge of Armagon by Ritual Entertainment (formerly known as Hipnotic Interactive).
After playing Armagon, you should also check out the
Death's Dominion Level Pack.
Dissolution of Eternity by Rogue Entertainment.
- Both official mission packs are generally acknowledged as better than the original game.
Very original Quake total conversion, with the greatest (make believe) machine gun I've ever unleashed. Worth paying for.
Commercial mod now freely available: Link
Xmen mod! Great models. Shame about the game-play. ...When good mods turn bad.
This mod has now been released free of charge, and can be found
here.
One of the first commercial mods. It has well modelled and totally new monsters, but the game-play doesn't cut it anymore.
