Quake Epsilon is a graphically enhanced build of shareware Quake 1 for Windows/Linux/Mac, which can be upgraded to the full version of Quake along with it's mission packs Scourge of Armagon and Dissolution of Eternity by copying the full-version .pak files into the correct folders.

About

It's made out of the Darkplaces engine and many mods from members of the Quake One forums and elsewhere (these are listed at the bottom of the page) as well as my own work. If it were not for these people, this build would not exist, so consider thanking the authors directly. These builds are legal and do not contain pirated content. Just simple unzip-and-play stuff.

There are four graphics modes, which you can switch between via an external batch file ('High' is default):

• Ultra - Recent machine and graphics card recommended. Reflecting surfaces, bump-mapping, environmental effects, multiple particle effects, better flames, high-polyon models, effected reflecting water, ultra quality texturing.
• High - For most modern machines. Geforce 7800 and dual-core 3ghz or better recommended. Environmental effects, multiple particle effects, better flames, high-polyon models, effected reflecting water, ultra quality texturing.
• Medium - For medium spec computers and laptops with reasonable onboard 3d chipsets. Transparent water, high quality texturing, graphical options optimised for performance while still retaining a 'modern' feel.
• Low - Recommended for older machines. Also designed to be as similar to original quake as possible for those who want a nostalgia trip. Fewer/no shader effects, lower-quality texturing, uses less memory and cpu.

The videos below show the differences between the four graphics modes, as well as some of the gameplay. Best viewed fullscreen at 720p:

Changelog at bottom of page.

Installation

Quake (shareware)

1. Unzip the quake epsilon zip file to somewhere on your computer.
2. Choose your graphics quality level (default is "high"):
   
   Windows: run (double-click) epsilon - change graphics quality.bat
   Mac/linux: run (double-click) epsilon - change graphics quality - linux and mac
3. Run quake:
   Windows: run (double-click) quake.bat
   Mac: run (double-click) quake - mac
   Linux: run (double-click) quake - linux x64 glx

Then go into video config and adjust your resolution and brightness/gamma to taste.
That's all!

Quake (commercial)

Follow the first two instructions for the shareware version as above then copy the "PAK0.PAK" and "PAK1.PAK" files from your commercial installation of quake (if you're using the steam version these will be in your steam/steamapps/common/quake/id1 folder) to the "id1" folder in your quake epsilon installation. Your computer will probably ask whether you want to overwrite the existing PAK0.PAK - do so. Then run the game as per the third step above.

Omitted content

I can't include the original soundtrack for Quake (and the steam version doesn't contain it either) for legal reasons, but it can be found around the net. Alternatively I've included my own retrotastic "Diabolipak" music replacement pack in the build, which I hope you'll enjoy.

The soundtracks for the mission packs are also not included with the steam download but can be found around the net.

Additional options

• To disable intro demos (running in-game graphics) on load, simply add the following text to the end of your darkplaces executable call in your batch/bash script:
  +map nomap
  ("nomap" can be any name, so long as it's not the name of an actual map).
• To learn how to customise the extra death animations, read id1/readmes/00__Quake-Small-Mod-Compilation-V3.61--Seven-20111205/Readme New Death Animations.txt.

Performance tweaking

• If you have performance issues, first try changing to a lower graphics quality level as per step 2. of the Quake Epsilon shareware installation procedure.
• If that doesn't help, you can try going into quake's options/video config and either reducing your resolution, antialiasing, texture quality or anisotropic filtering settings, or by turning texture compression on.
• If you're perfectly happy with the ultra graphics setting except for slowing down in areas with (reflecting) stained glass, try deleting id1/reflecting_overload.pk3 - you'll lose reflective glass but gain performance.

Bugs

• If you experience problems with black textures or black creatures, try turning off texture compression in options/video config - on some video cards, and with some video card drivers, it can cause problems.

• If you experience rainbow-coloured textures for some objects in Mission Pack 1 or Mission Pack 2 - copy the pak0.pak from your legal copy of MP1 or MP2 into the appropriate directory (hipnotic or rogue) - cause you've forgotten to do that! ;)

One bug that I am aware of is associated with the darkplaces engine, which is the gold door at the end of the first level in Mission pack 1. If you do not approach it correctly it won't open.

Workaround is: if you move to the left side of the door and slide slowly to the right while pushing into the door, you'll get it to open. This bug also occurs in HIP3M4 (The Gauntlet) on the Silver door. If you approach it running or to the left of it, it won't open. Approach it slowly and from the right.

• There is a common bug associated with quake where you lose some of your runes when you save the game. I'm not sure of the workaround for this, or what causes it (I suspect changing difficulty levels after a mission May trigger it) so just save your game often and preferably into a new save slot at the end of each 'episode' of the main game.

If you happen to like the music in the compilation, it's mostly taken from one album I did: xolve.bandcamp.com - it's free, and quite retro (pre-2000). Some of it was also taken from my other albums, thelorax.bandcamp.com (acoustic), exolve.bandcamp.com (electronica) and onefatalpunch.bandcamp.com (angst), which are more modern but not free.

changelog

version 2.0 - 12/05/2012:

Top level changes:

• Consolidated four builds into one, wrote batch/bash scripts for users to switch graphics quality levels (which swap graphics packages in and out and change game settings).
• Optimised rygel texture pack, fixing missing textures, improving performance (~10fps on my machine) and reducing download and loading times.
• Wrote bash scripts for running on Mac/Linux, retained executable permission status of darkplaces in package (thanks to LordHavoc and Andlinux).
• Added high poly packages for 'ultra' and 'high' graphics qualty levels.
• Consolidated build size is now about 2.2GB, about 2/3 the size of the original 'ultra' build and 1/4 the size of all of the previous builds put together.

Lower level changes:

• Changed TGA's to PNG's (when alpha's present) or jpeg in most packages to reduce size.
• Optimised performance settings and packages for each graphics level.
• Separated normal textures out (not used in Low quality level) from other packages.
• Optimised SMC effects enabled for each quality level.
• Optimised lighting settings for 'Low' quality level ('high' lighting).
• New sky for some levels (moondrunk/jenk/beafeater, me).
• Better teleport and slime textures for rygels pack (edited by me).
• Re-zipped pk3s using store. Faster loading, negligible size difference, better overall compression for downloadable zip (equates to 'solid' archiving for individual archives).
• Removed lightbeam support from reflecting overload. Until such point in time as computers quadruple their single core processing speed or darkplaces becomes multiprocessor-secure.
• A myriad of other fixes.
