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.

It's made out of the Darkplaces engine and many mods from members of the Quake One forums and elsewhere (these are listed in the readme for each pack) 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 a batch file ('High' is the default):

  • Ultra - Recommended for the bleeding edge of current (~2011) computers. Recent cpu recommended. Reflecting surfaces, bump-mapping, environmental effects, multiple particle effects, better flames, high-polyon models, effected reflecting water, ultra quality texturing.
  • High - Recommended for most modern machines. For good machines with good graphics cards. Geforce 7800 or upwards, dual-core 3ghz & upwards 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 the 'modern' feel of the quake epsilon build.
  • Low - Recommended for older laptops, graphics cards without shader support, and older machines in general. But it's also designed to be similar to the original quake as possible for those who want a nostalgia trip but with higher quality textures. Few/no shader effects, uses the QRP texture pack, which is less gritty and grimy but more like the original quake, and uses less memory.

Please note that it runs much faster on Windows, so that would be my platform of choice if you have the option.
I don't want to clutter this summary, so more details and all credits can be found in the readme for each pack and on the homepage (http://www.soulstudios.co.nz/epsilon).

Dimensions of the Past image 1


Well, it's that time of year again and 2016 being what it was, I was feeling the need to shoot something.
Enter DOPA (Dimensions of the Past), MachineGame's 20th-anniversary celebratory quake episode release.
But of course the path to getting these things running well is never smooth; so I made an expansion, ie suffered so that you don't have to (as per usual), figured it out, gave it it's own soundtrack, tied it up in a pretty blue ribbon, cast spells on it, etcetera.


The soundtrack is Nine Inch Nails, which I feel is appropriate given he did the original game's soundtrack, and is a composite of his two free releases, Ghosts I and The Slip (both of which were released under a non-commercial, attribution, sharealike creative commons license). I just selected the appropriate tracks for each level, mixed/looped/volumed them properly together, and set up each level so it had an individual pair of songs - the result is a 1.5-hour soundtrack.

So now in the time I take away from constructing voodoo dolls of certain presidents, I release this into the wild, where it belongs. Run free, little lamb:
Moddb.com

Also I did some updates for the other packages, of minor and major degrees dependent on the package in question: new versions can be found in the downloads section, with additional options on the epsilon website. Summary of changes:

v2.54

DOPA - improvements over original:
1.5-hour soundtrack based on NiN's free albums 'Ghosts I' and 'The Slip'
the usual high-quality texturing, models, effects via epsilon build
better lighting courtesy of BloodVengeance (with some corrections by myself)

Travail:
Massive improvement to lighting
Corrected laser bolts on enforcers
Corrected lumas for enforcers, grunts, knights, hellknights
Corrected some lightmaps
Changed water type for better performance in some areas

Abyss (mission pack 3):
Improved lighting, texturing, blood and flame effects.
Ammo icon corrections.
Improved hellknight skin
Correction to missing hires skins if MP2 not installed

Quake original, mission pack 1 and mission pack 2:
Incorporation of changes from 2.53 into main build (Corrections to linux bash scripts)
MP2: Updated to v1.0 release QRP DOE textures and normal maps

Beyond Belief:
Map6 fix
Map1 fix
Improved textures
Some lighting improvements

The Myths:
Update to lighting on map 3
Improved fiend skin

Lastly, I just wanted to mention that as of the v3.2 (sometime in 2015) Nvidia graphics drivers, Ultra mode in epsilon experiences texture glitches on an nvidia graphics card, due to a bug relating to bump-mapping.
To fix this, rename "darkplaces.exe" to "GLQuake.exe" and edit your .bat files accordingly.
The other long-term solution is to complain to nvidia - be my guest:
Nvidia.com

You can also work around this by using 'High' quality mode. Or a really old driver version.
Also the epsilon website has moved.

And now, I bid you adieu; there are many things to do before the new year is upon us.
Peace.

While doing my YouTube play throughs, I noticed that this mod comes with a old version of Darkplaces engine (from 2012). The latest stable version is from 2014 and the latest development version is from April 2017. For anyone playing this, I recommend grabbing the latest stable build of Darkplaces Engine from here: Icculus.org Do not use the latest development version as it seems to have missing textures in it. I am not sure if the other mods are up-to-date or not, but I guess it is worth to check.

It doesn't work with epsilon. The build I use is an older one, because it is faster than the newer non-developmental ones.
At any rate newer != better, always.

Hey, the Nvidia glitch can be fixed renaming DarkPlaces.exe to GLQuake.exe...

I discovered it by looking at the Quake profile in the Nvidia Profile Inspector...

Using Quake Epsilon v2.54 here. There's no way to make it play the tracks from the original soundtrack in the right order. I've tried renaming the tracks and folders differently but nothing worked. The format was always .ogg. I can hear the music while playing, but the tracks' order is messed up. For example, right at the beginning the "Main Theme" with guitars etc. should be playing; instead, track006 is.
I think there must be a bug or something, but if anybody could help, that would be much appreciated.
This is probably the best mod for Quake so it would really be a shame.
