Graveyard Keeper 2 Zombies: Unlock → Work → Optimize (One Hub)

This Graveyard Keeper 2 guide takes you from no zombies → zombies producing → knowing what to improve next, in one pipeline: free zombies, the Resurrection Table, tools and mastery, supplier stations, collars and the errors that stop you.

TL;DR — Zombie pipeline stages

Part of the Corpses hub — More corpse & zombie guides

Stage 1 — Unlock gate and the 5 free zombies

The campaign hands you five zombies before you craft anything:

• Clear the gate first. Dream Dust is what opens the Plague Doctor's lab and his zombie reward — full steps on Dream Dust unlock.
• Don't burn materials early. Put the five free zombies on the most tedious jobs (hauling, chopping, farming) and save collars and Reanimation Liquid for good corpses.

Common fail: skipping Study Table research before brewing Dream Dust. Read the Dream Dust page before blaming the Resurrection Table.

Stage 2 — Resurrection Lab, table & first workers

Two timing rules that save a week:

• One device use raises every prepared table. Prepare all four tables first (Lust, the day before, is a good prep day), then pull once. After that the lab has no power until the very end of the next Lust.
• Prayer for Storms gives the "God of the storms" blessing: for 1 h 30 min the device works on any day, as often as you like.

Polished Stone, if you are stuck: 4 Piece of stone + 1 Melted Fat + 2 Sand at a Stonemason's Workbench makes 4.

What goes on the table

Brewing Reanimation Liquid: Gunter's Necronomicon quest unlocks the Reanimation Liquid technology. The mix is brewed at Laboratory II (three ingredient slots) and needs exactly 2 red + 1 green + 4 blue runes. Any ingredients that add up work; two examples are Copper Nugget + Night flower + Night flower, and Clay + Alcohol + Salt.

Zombie collars

Blue Crystals are sold by Gunter and also found in the Swamp. The Jeweler sells Bronze collars, Golden from trader level 2 and Steel from level 3. Every collar costs Faith, so plan your sermons — Faith for zombie collars.

Stage 3 — Put zombies to work

Every new zombie starts with 0 mastery. Placed on a bench as-is, it just stands there. That is not a bug.

A zombie has the Keeper's five masteries — Building, Smithing, Farming, Book writing and Anatomy. For any recipe, its mastery is: nodes it bought on that tree + the tool in its hand + any perk for that job. It holds one tool (or weapon) and one armor.

Tools → mastery

Fishing rods follow the same +1 / +2 / +4 / +6 steps for Farming. Book writing tools (Primer, talismans) and Anatomy tools (Butcher's Kit, Surgeon's Kit) give +1 to +4. Some items are weaker than the name suggests: "Iron tools" give +2 Smithing while an Iron Hammer gives +4 — read the tooltip.

Give every new zombie the best tool you own for its job; it is the fastest way to reach a recipe's mastery requirement. A shovel also covers kitchen work, because cooking is Farming.

Stations that need a specific tool

Most other benches (sawhorse, furnace, kitchen table, millstone, writing desk, jewelry table) need no specific tool — only enough mastery, which a tool can still supply.

Supplier + worker: the two-zombie rule

Workstation zombies do not fetch their own materials. A zombie on a Zombie Supplier Station delivers inputs to every workstation zombie in its area and clears finished products into chests. So every automated job is a pair: one zombie crafts, one hauls.

1. Unlock the Zombie Supplier Station and build it near your benches, with a storage chest.
2. Put one zombie on the supplier station (no tool needed).
3. Put a tooled zombie on the bench, select the recipe and quantity, add to queue.
4. Put the materials in the chest and watch one full cycle.

Also useful:

• Zombies learn on the job. They earn tech points while they craft and spend them on their own trees.
• Gardening is separate: research zombie gardening, build a Gardener Stand, give the zombie a shovel, and place crop tablets from the build menu on each row so it knows what to plant.
• Patch notes: 1.005 made pending zombie crafts show when the skill level is too low; 1.006 fixed kitchen zombies that used or burned ingredients without producing the dish — update before you debug.

Stage 4 — Collars, organs, red skulls (intro)

Step-by-step builds: Build a 5 or 10 red skull worker.

Zombie limit (the Excessive zombies debuff)

The zombie limit equals your Resurrection Lab's quality. Going over it gives the Keeper Excessive zombies, which cuts what every sermon pays. Guides disagree on whether it also stops the table (see Troubleshooting); either way:

• The count is checked when a PR Machine program starts or ends, not at the moment you resurrect.
• The PR Machine raises the limit; it is loaded on Gluttony only. Its first program adds +10 for a week for 2 Charged hypno-devices; later programs use newspapers.
• A successful Hypno Prayer clears the debuff when granted.

Patch 1.007 fixed the PR Machine not working.

Early on, keep the army small: one specialist per mastery you need, plus haulers.

Stage 5 — Toward porters, factory and combat

Once several zombies work reliably:

• Stop adding chaotic manual assignments and open the checklist on Automation.
• Porter Station zombies carry raw materials to the Factory; Zombie Carousels add factory power.
• Unlock techs in order → Tech Tree Priority.

Combat squads: after the first battle, the Barracks let you form squads of 4. A zombie fighter needs armor and a pike or a bow — swords are not an option. A zombie missing either piece won't join the fight. Low-red bodies you don't want to specialize are fine here.

Troubleshooting: every Resurrection Table error

Zombie exists but won't work

Steam update 1.005 also fixed several "cannot resurrect despite requirements met" cases.

Done when checklist

• [ ] Dream Dust / Plague Doctor gate cleared; 5 free zombies collected

• [ ] One supplier + worker pair runs a full cycle without you
• [ ] You know your collar caps (5 / 10 / 99) and your zombie limit

FAQ

Q: How do I get zombies in Graveyard Keeper 2?
A: The story gives you five for free: 2 from the Plague Doctor at the end of the Dream Dust quest (Sweet Dreams) and 3 from Gunter (Friendship Written in the Stars). After that you raise your own on the Resurrection Table.

Q: What do I need to resurrect a zombie?
A: A corpse with all six vital organs, 1 Reanimation Liquid and a Zombie Collar whose red-skull cap fits the corpse, on a Resurrection Table. Use the Resurrection device on Envy, or on any day while the Prayer for Storms blessing lasts.

Q: Why won't my zombie work?
A: New zombies have 0 mastery. Give it a tool for the matching mastery (a better tool gives more mastery), put it on a station whose recipe it can meet, and make sure a zombie on a Zombie Supplier Station is bringing materials.

Q: How many zombies can I raise at once?
A: You can build up to 4 Resurrection Tables. One use of the device on Envy raises a zombie on every prepared table, and the lab then has no power until the end of the next Lust.

Q: What are the zombie collar limits?
A: Bronze Zombie Collar up to 5 red skulls, Golden up to 10, Steel up to 99. Each is made at the Jewelry Table from 1 matching ingot, 1 Blue Crystal and 3, 5 or 10 Faith.

Q: Can zombies fight?
A: Yes, from the Barracks in squads of 4. A zombie fighter needs armor and a pike or a bow; zombies cannot use swords.
