Graveyard Keeper 2: How to Make Zombies in the Morgue Resurrection Lab
By completing the Sweet Dreams quest in Graveyard Keeper 2, restoring the Resurrection Lab, brewing Reanimation Liquid, and affixing appropriate collars, you can establish an active workforce every Envy day.
Unlocking the Resurrection Lab and Repairing the Device
Zombies serve as a core automation system that touches nearly every logistical chain in the game. You unlock access to the system after finishing the quest Sweet Dreams. Upon completing this task, the Plague Doctor rewards the Keeper with two complimentary starter zombies to jumpstart manual chores.
To create additional undead workers, head into the Morgue and unlock the Old Door leading into the Resurrection Lab. Inside the chamber sits a broken Resurrection Device. You must repair this machine by providing 1x Bronze Detail and 2x Wooden Plank while possessing Mastery 3. Once restored, the device can activate multiple Resurrection Table workstations in a single discharge, allowing you to prepare multiple workstations simultaneously (community testing indicates space for up to four tables across the room).
Corpse Selection, Organs, and Red Skulls
To prepare a body for resurrection, place a corpse onto an available Resurrection Table. The corpse must retain all of its organs (detailed in our autopsy table guide) and cannot suffer from any Surgeon’s Error penalty.
Unlike burial plots that prioritize white skulls, zombie perk slot capacity scales directly with corpse skull count. When sorting deliveries from the donkey, inspect corpses on the autopsy table and prioritize bodies with higher skull counts to equip higher-tier collars and unlock more perks. If you produce an unwanted minion or clear out obsolete workers, Update 1.011 allows old zombies to be cremated in the crematorium.
Brewing Reanimation Liquid and Crafting Collars
Every resurrection procedure consumes one flask of Reanimation Liquid and requires an equipped Zombie Collar. You can purchase liquid directly from vendors like Gunter and the Alchemist, or distill it personally at an alchemy station. Efficient brewing formulas include combining Tin, Water, and Alcohol, or processing Clay, Alcohol, and Salt. Studying the liquid requires 20x Science points and yields 30 red, 50 green, and 25 blue research points.
The quality tier of your corpse dictates the collar required at the Jewelry Table:
- Bronze Zombie Collar: Handles 0–5 skulls. Crafted with 1x Bronze Ingot, 1x Blue Crystal, and 3x Faith under Reanimation tech (or purchased from the Jeweler; study requires 5x Science).
- Golden Zombie Collar: Accommodates 0-10 skulls. Requires 1x Golden ingot, 1x Blue Crystal, and 5x Faith under Reanimation II tech (study requires 10x Science).
- Steel Zombie Collar: The top-tier collar supporting 0-99 skulls. Built using 1x Steel Ingot, 1x Blue Crystal, and 10x Faith with Mastery 12 under Reanimation III tech (study requires 20x Science) — forge or purchase steel using our how to get steel guide.
Starter collars are not permanent fixtures and can later be replaced with higher-tier collars as better resources become available.
Weekly Envy Rituals and Setup for Work
The Resurrection Device operates exclusively during Envy, which corresponds to the weekly green day on the celestial calendar (explained in our days of the week guide). The machinery remains locked and cannot be interacted with during any other weekday. Because the device functions only once per week, you should stage several corpses on adjacent tables beforehand, apply their collars, and infuse each with Reanimation Liquid.
When green day arrives, trigger the device to reanimate every prepared corpse simultaneously. Once risen, your newly created workers stand ready to receive station assignments and logistical orders; see our detailed guide on how to make zombies work to connect your workforce to supply stations and automated workshops. Collision issues on the resurrection table were resolved in Patch 1.009, and a locked gate bug was patched in Update 1.011.
