Abyss of Pandemonium
You have been through time, faced monsters most mortals would have died just looking at. It would pretty much seem like your work was done and you could retire. But it's not a nice universe we live in now is it?
Quake's general, The Dark Reaver Legond, has returned from conquering yet another dimension. Expecting great fanfare upon arrival, Legond receives only the sad news that a lone Earth denizen has stopped Quake not once, not twice, but on three separate occasions. Outraged, Legond gathers the now infamous Dark Horde from the far reaches of the universe and plots the destruction of this mortal.
Legond has a whole slew of new traps and nasties in store for you before dragging you into an unknown dimension to do battle with you face to face. This is going to be your most terrifying and difficult mission to date.
Once again it's up to you to stop Quake's armies, but this time, they know you're coming and they're ready for you. Legond will stop at nothing to see your severed head spiked above Quake's throne.

Abyss of Pandemonium was an unofficial missionpack for Quake. It is noteworthy for a few reasons. First of all, it previewed quite well! Secondly, the developer, Impel Development Team, had a dispute with their publisher over Copyright infringement.
As a result of that dispute, the team released the missionpack as shareware for free. It was split into multiple parts, but was later combined into aopv105.zip.
Patch v1.09 made it so that the weapon pickups for the Super Shotgun, Grenade Launcher, Rocket Launcher and Lightning Gun have a 50% chance of becoming pickups for the Grenade Launcher, Napalm Gun, Rocket Powered Impaler and Pulse Rifle/LG-2 Prototype respectively. So if you want to do reproducible runs of this addon, you might want to stick with a version prior.
