it simply requires zdoom v2.8.1 , heretic.wad (I think you can still buy it from raven or dl it from steam or what ever it is you do these days) and the rest is history.
In late 2014 sgt shivers made a texture add on to further quake-up the heretic maps.
I also knocked up three new quake themed skies for each episode!
Although not necessary to run, I feel the texture pack enhances the whole quake/heretic mash up nicely and adds further quakeyness to the stock heretic levels. In fact its amazing how different they feel with new textures!

So to run the mod with standard textures your heretic cmd-line should look thus:

zdoom.exe -file quake-dih_3.pk3

and with textures:

zdoom.exe -file quake-dih_3.pk3 -file textures_dih.pk3

and with added quake monster randomiser:

zdoom.exe -file quake-dih_3.pk3 -file textures_dih.pk3 -file monsters_dih.pk3

oh, and gzdoom users should add the file GL_skies.pk3 after the textures. (not vital but totally worth it)

for those who may not know, zdoom limits the textures to the heretic palette. gzdoom does not.
that is why the skies are a rather plum-purple shade in the textures_dih.pk3 file.
however, gl_skies.pk3 has sky textures in the familiar pastel-magenta shade you will remember from quake and as such are much nicer visually and fit in with sgt. shivers textures when playing in gzdoom. but gzdoom only. they simply look like shite in zdoom...

for help look though the info section in the in-game menu when playing (or fress f1 and then enter to scroll through)

oh, and for those who don’t like surprises here is a list of what replaces what in the game;

gauntlets - grenadelauncher
wand - shotgun
crystal – single shotshell
geode - shellbox small
xbow - supershotgun
arrows - shellbox small
quiver - shellbox big/rockets small
dragonclaw - nailgun
claworb - nails small
energy orb - nails big/rockets small
hellstaff - supernailgun
lesser runes - nails small
greater runes - nails big
mace - thunderbolt
maceammo small - cells small
maceammo big - cells big
phoenix rod - rocketlauncher
fire orb - rockets small
inferno orb - rocketsbig
vial - stimpack
flask - medkit (but portable as flask is)
tome - quad damage
ring - pentagram
armour - quake armour
dropped ammo – nails, shells or rockets in a backpack

the official soundtrack to descent into heresy is available to DL now!

it the aftershock-project remake of the original quake soundtrack by Trent Reznor and crew, compiled for specific use with heretic maps by the talented Legend.
it is clearly inspired by and reminiscent of NIN's original quake soundtrack but is different enough to feel new!

we at the OSJC feel it works to further enhance the total-quake-immersion that DIH attempts to bring to the world of heretic.

you'll find it as an add-on patch in the files download section...

OSJC's Quake: descent into heresy - a heretic mod for zdoom - revisited


This mod is awesome. Pretty inspired to put Quake with Heretic. Both have fantasy elements so the Quake stuff fits like a glove (the texture pack is a must). I also find Ketchup fits quite well also, though it seems to negate the custom monsters unfortunately.

Cheers! However I'd not recommended using other mods with this mod as errors like the aforementioned will no doubt abound...

Your mod is cool, really. Like I said, Id Software should have been developed a new Quake game based to the first one instead of Champions, in my opinion.

My question:
Do you think to do a mod like this one or Major Crisis but in the style of Kingpin: Life Of Crime?

thanks for your support.

as for your question. well, as I've never heard of/seen/played kingpin its a solid no.

However, I have had an idea rumbling through my mind for a Doom mod based on malice for quake which does have a gangland-mercenary crime-boss theme to it...

Malice for Quake was one of the best Total Conversions out there - and has one of the best (if not *the best*) hover-boards in a game

looking forwards to giving this mod a spin and seeing what can be done with Malice (if anything) =)
