Description:

To couple with the Half-Life: Extended Workforce addon comes a huge collection of Zombie Half-Life SNPCs taken primarily from Half-Life: Extended, gamebanana, and a few personal edits based off of Half-Life Zombie Edition, made into their own SNPCs to form a giant zombie horde!

This addon is NOT in collaboration with the original mods, Half-Life: Extended, Half-Life Zombie Edition, or any other mods. This is a personal pack of mine I think a lot of people would enjoy.

HALF-LIFE: RESURGENCE IS REQUIRED FOR INORDER FOR THIS PACK TO WORK!


Here’s a quick, non-detailed list of some of the SNPCs added!

-BASIC ZOMBIES-

Basic Zombies have a plethora of new outfits and skins matching their extended workforce counter parts, some of them even having varied stats depending on their model!

All of the new jobs introduced in Extended Workforce now have zombie variants such as Janitors, Service Personnel, Office Workers, Chefs, Construction Workers!

Even characters who originally had no zombie variants in extended such as cleansuit, female, and fat scientists have had custom zombie variations made for this pack!

Security Zombies now also have Otis variants, and Heavy Security variants!

HECU Zombies now have various bodygroups for other HECU members! Certain Members such as the engineer and medic have special traits, like explosive gas tanks and dropping healing bandages!

There’s even Survey Team Member Zombies, wearing different HEV suits to protect themselves!

ALL basic zombies now look for and eat HUMAN corpses to heal their health when they’re hurt!

Headcrabs latched to ALL basic zombies now have a rare chance to jump off the body if not shot directly in the headcrab!

ALL basic zombies can now be set or spawned "As a guard" to make them play dead/sleep, just like their slumping feature in HL2! Only getting up when players approach them!

-ZOMBIE EDITION MUTATIONS-

The special mutated zombies from Half-Life: Zombie edition make a special appearance in this addon! With brand new low definition models with custom animations made EXCLUSIVLY for this pack!

Including The Breeder Zombie, who fights using baby barnacles, baby headcrabs, and full headcrabs!

The Crasher Zombie, boasting an extremely high healthpool, spit attacks, and even a military variant that has their blocking ability from HL:Z!

The Rusher Zombie, an incredibly fast zombie with lunging abilities, they never stop their chase till someone is dead!

The HECU Grenadier, a VERY LOUD enemy, but you’ll want to hear them, as they can pull a grenade on you whilst in combat, so keep a look out for them!

Oh, and did I mention the zombie edition specials ALSO come with model and texture variation?

-HEADCRABS-

Headcrabs have been given a few uncommon skin variations of different colors, to add a bit of variety to each crab!

Gonarchs and Baby Headcrabs have been given the same treatment as well!

Headcrabs now also come with a Xenian portal entity that ONLY spawns basic Headcrabs!

Headcrabs can now be spawned or set "As Guards" to have them burrow and hide in the ground like Half-Life 2!

-MINI BOSSES-

Two BRAND NEW Mini Bosses exclusive to this pack have been added!

The Gonarch Juvenile, a younger, smaller Gonarch, yet to develop the ability to give birth to baby headcrabs, but don’t let that fool you, it’s very aggresive and has a good aim with its acid spit!

The Metamorphanome, the perfect mutation, all of the Zombie Edition mutations brought together to from an incredibly deadly foe with great strength, mobility, and the ability to create more headcrabs.

-GONOMES-

Gonomes have also been given the same treatment as other zombies, given the ability to eat corpses and boasts a large number of variations, with each Gonome having slight stat differences!

-BONUS HL2 ZOMBIES-

The Poison and Fast Zombies/Headcrabs from Half-Life 2: Classic also appear in this mod as bonus SNPCs, the poison zombie given special variations to have them fit within the black mesa research facility a bit better!

Currently their animations are still a bit rough from HL2: Classic, but they might be updated a bit more in the future!


An addon that I had been wanting to make for AWHILE, very strange development cycle. This addon will most likely receive various updates content updates at random periods, especially to add new zombies, or improve old ones (especially those HL2 ones… I’ll get to work on those sometime soon…)

I HIGHLY recommend using this pack with my Extended Workforce addon, to have human variants of some of the zombies in this pack!

"Can Headcrabs turn humans into zombies?"
As of release, they cannot, it’s quite complex truthfully, in a later update though I’ll be trying to look into some special SNPCs for the pack designed to have said features.

"What about HECU? Or Xenians?"
Any other NPC added to this pack will be sticking to the theme of Zombies or Headcrabs of some sorts. As for Aliens and Marines, they will be their own separate pack. But don’t hold your breath, I don’t know when I’m going to work on/release those.

Comments requesting HECU or Xenians will be deleted
