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).

Not really related to either Quake or Epsilon, but I figure there's a large enough crossover of Quake fans who're also Doom fans that this is relevant:

Doom 2016's soundtrack suffers the same fate as most modern metal; overcompressed, over-limited and difficult to listen to for more than 10 minutes at a time without developing some subtle or obvious ear-fatigue. Having said that, I love the crap out of it. So I was especially happy to find that the vinyl variants don't suffer the same fate- unlike digital, vinyl has physical limitations on how much average volume you can sustain for long periods - too much, particularly in the bass, and you start to get needle jumps and obvious distortion.

Comparing the waveforms for, for example, Rip and Tear, looks like this between Vinyl and Digital:

volume match comparison

Vinyl has approximately -18db RMS (average volume) across the song, Digital is -11db - given that a 10db difference is roughly double the volume, a 7db difference indicates roughly 2/3rds more dynamic range in the vinyl. What does that mean exactly? Well, you would've heard of the loudness wars and how they basically ruined music in the 90's and beyond. If you haven't, basically humans perceive even slightly louder material as being subjectively better -to a point - so even sound engineers are easily swayed by something sounding slightly louder on average. But you do that enough and your material starts to sound like poopbutts compared to if you took the original and just upped the stereo's volume knob. Case in point:

This is the intro for Rip and Tear, first in digital then in Vinyl - both have been volume-matched so that their subjective overall volume is roughly identical. The digital version is from the 24-bit 48khz masters that come with the Vinyl box set btw. When you listen the first thing you'll hear in the vinyl is that the drums are punchier, and less compressed - overall the mix is more pleasing to listen to, particularly on a good stereo. And while most of the vinyl rip's I've heard of the soundtrack have seemed to apply some sort of volume limited or compression post-recording (or at least recorded it at a high enough level that the input clipped), I wanted a version I could hear to that was easier to listen through to the end. In one session. Something pleasing to the ear and as close to how the original pre-vinyl digital would've sounded, as I can get.

record player

I borrowed a friend's Technics SL-1280 mk2 record player - also known as 'the' record player - with a custom stylus, and plugged it into my recording studio's black-lion-audio modded 896HD with BLA microclock. I recorded at 24-bit 96khz, at the ADAC's sweet spot of ~-22db rms, allowing plenty of headroom for sudden volume changes. I recorded each side of each record about 4 times - I never realised new vinyl often has some gunk in the grooves that has to be rimmed out either by playing or cleaning - at any rate, after four playbacks I was able to get good takes.

Then, time for post-processing. I decided not to do much EQ'ing, though I did experiment a little, I found the straight recording didn't need it much - a small boost of .1db in a high shelf in ozone is all I applied, and even that was not strictly necessary. After this I tried various declicking setups using ClickRepair (a brilliant piece of software BTW). But Mick Gordon's work actually contains a lot of sharp transients which oftimes sound like clicks but aren't - so just applying declicking across the board didn't work. I decided to do it manually, listening through to each side and taking out each click as it arose.

Tracktion editiingg

After about 8 hours work it was done, the project taking up 20GB of space overall. The result was a nice full-dynamic-range 24-bit 96khz version of Doom 2016. This is the soundtrack the way it is meant to be heard. Unfortunately I'm not aware of any free streaming services online which do 24-bit 96khz, so I've downsampled to 24-bit 44khz for the youtube version below - enjoy.

Great mod collection, I am playing in ultra.
There are error messages about sounds that pop up.

"SV_SOUNDINDEX("WALK/GENERIC2.WAV"): NOT PRECACHED (FIX YOUR CODE), PRECACHING ANYWAY

The same for "ZOMBIE/HIT"

Strange, I haven't experienced that.
Those don't match actual sounds I've seen in either quake or AD, so unsure why those messages are coming up.
Will hopefully have another run at some point and see if I can replicate it.

Sorry for the inconvenience. I'm having trouble running the game through the batch files. They don't recognize my PAK files for id1, hipnotic, and rogue, even though I've installed them all the way you specified (yes, I legally own all the games and copied the correct PAK files to the correct directories). In fact, the game batches don't even open up at the executable screen unless I move them to another folder, though it still won't detect my PAK files, saying I don't own them. The graphics adjustment batch works. I got the base game to run by opening Darkplaces, but can't get the Mission Packs to run. I noticed someone else had this issue a few months back, so I was wondering if you found out the issue behind this? I have Windows 10, if that helps at all. I also disabled my anti-virus to see if that helped, all to no avail. Renaming the base folder from "Quake - Epsilon" in my Steam folder to "Quake" didn't help either. Thanks in advance, and fingers crossed :]

Scratch that, I found a solution. I just made my own batch file called armagon in my Quake - Epsilon directory with "run darkplaces.exe -hipnotic" and it seems to work for Mission Pack 1. Of course I had to transfer my config file from id1 since this simple batch doesn't do that. Thought I'd let everyone know in case they had trouble with the existing batch.

Thanks, I'll look into it.
Could you try adding these lines to the top of your batch and see whether they stop it from working:
%~d0
cd %~dp0

If they do, let me know, otherwise also try changing "run" to "start" and see what that does. Thank you-

Sorry for the delay, friend, been busy.

I tried every variation you mentioned, both with and without the cd lines and switching between "run" and "start", and the issue is when the batch starts with "run", as the batch screen will show for a second but the game just doesn't start. The "start _.exe" command works for certain, with or without the cd lines. If "run" is present, it won't work with or without the cd lines. I mistakenly said in my original post that "run darkplaces" works, but it was actually "start darkplaces.exe".

Probably the greatest way for someone to get started experiencing Quake. Thanks for putting in so much work to bring this to life and complete it over the years.
