Graveyard Keeper 2 Tech Tree Unlock Order — Autopsy

Where autopsy tech lives

All autopsy research sits in the Anatomy and Alchemy tab. It opens when you place the first body on the autopsy table. The branch holds 47 technologies over 13 columns; researching all of it costs 2,072 red, 1,172 green and 1,642 blue tech points, and it contains three reputation gates (Albert 10, Nun 25, Gunter 20). Every technology needs all the technologies linked to its left. (Wikily)

Until you research an organ’s technology, that organ’s slot on the table shows as unknown — you can’t operate on it or even see its skulls (gk2db). So the tech tree, not just your Anatomy mastery, decides which organs you can touch.

Autopsy tech spine (in unlock order)

Costs are red / green / blue tech points for that technology alone.

Adding up the five paid steps from Skin and Bones to Autopsy, Master comes to 65 red, 35 green and 47 blue tech points. The awkward one is Embalming I: you must buy it (50 red) before Autopsy, Master will open, so the brain is always the last organ you can work on.

The three kits are crafted at the Jewelry Table from Leather Scroll (made from Skin at the Writing Desk). Each kit is unlocked by the autopsy tech shown above (Wikily, gk2db).

Late morgue tech: Embalming III and Practical Potions

These sit far down the branch, behind the alchemy and reanimation path rather than the autopsy spine:

• Embalming III (150 / 0 / 150) — requires Reanimation II. Unlocks Injection for Corpses, Injection for Zombies and Embalming Table II. Injections trade red skulls for white (or the reverse) and need a Comet’s Tail on top of the Solution ingredients. See Embalming.
• Practical Potions (0 / 100 / 100) — requires Alchemy, Advanced (200 / 0 / 100), which itself needs Battle Potions III (70 / 70 / 70). Unlocks gold Skin, Bones, Skull, Heart, Brain and Guts recipes and the Organ Improver: combine an organ of any grade with a white-skull or red-skull Organ Improver at the Formulation Bench to get that organ’s top-grade form (gk2db). See Organs.

Neither Wikily’s nor Fextralife’s list of the 47 Anatomy and Alchemy technologies includes an “Embalming II” — the tree goes from Embalming I straight to Embalming III.

Reanimation / zombie tech (parallel path)

Collars cap a zombie’s red skulls: up to 5 on Bronze, 10 on Golden and 99 on Steel (gk2db). Raising needs all six organs and no Surgeon’s Error, so plan zombie bodies before you cut. Whether white skulls matter for that body is on zombie prep; red skulls in general are on red skulls. What Reanimation Liquid is, the Clay + Alcohol + Salt recipe (2 red / 1 green / 4 blue), Gunter’s Necronomicon unlock, and what one bottle does to a corpse are on Reanimation Liquid.

Anatomy mastery: what each organ needs

Tech decides which organs you can operate on; Anatomy mastery decides whether the operation goes cleanly. Required mastery rises with the organ’s grade (bronze / silver / gold):

At or above the requirement every tick succeeds; below it, each tick succeeds with a chance of your Anatomy divided by the requirement (Wikily). Falling short can leave a Surgeon’s Error (−1 red, −1 white skull). Sources for Anatomy mastery, per gk2db: up to +5 from the Anatomy talent tree, +1 / +2 / +4 from the Butcher’s / Surgeon’s / Master Surgeon’s Kit in the hotbar, +4 from Expert anatomist (autopsy table only), +2 from Third Eye Salt (7½ minutes) and +1 to +3 from a Vegetable salad (one day). Third Eye Salt is a potion, not the Salt in the reanimation recipe — what it does and how it is mixed. Talent tree + best kit + Expert anatomist comes to exactly 13 — the figure top-grade hearts, guts and brains demand. Full walkthrough: Autopsy guide.

Anatomy perk tree (inspiration points, not tech points)

The Anatomy talent tree has 20 nodes: 5 raise Anatomy mastery by 1 each and 15 are perks. Each node costs one Anatomy inspiration point; buying all 20 takes 94 notches of the Anatomy inspiration bar (Wikily). The morgue-relevant ones:

• Surgeon — every autopsy operation (removing, adding or swapping organs) starts with 2 successful ticks already done.
• Expert anatomist — +4 Anatomy mastery when working at an Autopsy Table. Requires Surgeon.
• Treasure Hunter — organ removals pay out coins (see the note below on how much).
• Researcher — research items faster and with less energy.
• Scientist — studying items may uncover stories or yield extra points.
• Cremator — doubles Ash and Salt from Crematorium I and II.
• Son of a butcher — the tooltip promises cheaper autopsies, but Wikily reports autopsies cost the same energy and insanity with or without it.

Getting the tech points

• Blue is the bottleneck early. Autopsies are the first reliable blue source; later, studying items scales better (games.gg).
• Pick every pocket. Picking a pocket can’t fail, needs no mastery and gives 1 blue tech point each time (gk2db).
• Every extraction pays. Each organ removal earns 1 red plus 1 / 2 / 3 blue for bronze / silver / gold grade, on every corpse (Wikily).
• Study each organ once. The first study of each organ type at the Study Table pays a large one-off batch of tech points; you keep the item (gk2db).
• Don’t bury first. Whatever is still inside a body goes into the grave with it, and so do its points (games.gg, gk2db).

Still unconfirmed or disputed

• Treasure Hunter payout. The perk text says organs “occasionally” contain silver; Wikily’s corpse page and gk2db both say every removal pays 10 bronze/copper (gk2db adds picked pockets too). Exact payout not yet confirmed in play.
• Whether a kit is mandatory. games.gg says operating without a kit guarantees failure and that kits need Metallurgy mastery 3–6 to craft; gk2db treats kits as an Anatomy bonus (+1 / +2 / +4), and Wikily says autopsy work can be attempted with at least 1 mastery. Carry a kit either way.
• Surgeon’s effect. games.gg describes Surgeon as revealing hidden skull values; Wikily and gk2db describe the 2-tick head start. Check the tooltip on your build.
• Organ Restorer. One Wikily page says it repairs a Surgeon’s Error; gk2db says nothing crafts or sells it and the error is permanent.
• Different tech names in some articles. A few early guides list technologies that do not appear in either wiki’s 47-technology list. This page uses only the names and costs both Wikily and Fextralife agree on.

Which tech to buy next

Costs below are the ones already in the autopsy spine. They are not a new survey. The fork is about the body you are about to waste.

Do not buy Embalming III to fix a body you could have cleaned with Blood, Fat and a Solution for Corpses. Do not buy gold organ recipes (Practical Potions) while you are still failing quality-1 skulls. The cut order is the cheaper check.
