GK2 Autopsy: Cut Blood and Fat First (Anatomy Floor)

What autopsy does in GK2

Wikily’s Corpses and autopsy page: every corpse is six vitals (Skin, Bones, Skull, Heart, Brain, Guts) plus soft parts (Fat, Blood, Flesh). Total White and Red skulls are the sum of those parts; removing or swapping organs at the Autopsy Table changes the totals.

Public guides (games.gg, Prima, Fextralife) agree on the split goal: White for burial / graveyard quality, Red for zombie perk slots. Decide the path before you cut — see burial prep and zombie prep.

First session at the table

Use this the first time a body is on the table. It only restates rules already on this page; the Anatomy tables below are the same floors.

1. Name the ending. White is for burial and graveyard quality. Red is for zombie perk slots. Decide before you cut.
2. Blood and Fat first on a burial. Wikily lists each as 1 Red. games.gg and Prima treat them as the free cleanup. Skip them on a zombie keeper if you still need that red.
3. Pockets before organs. Picking pockets does not fail. Below an organ’s Anatomy floor you usually lose the organ, and a bad result replaces the slot with a Surgeon’s Error (−1 White / −1 Red) that also blocks resurrection.
4. Bring a kit for a hard extract. Prima and games.gg: operating without a Butcher’s, Surgeon’s, or Master Surgeon’s Kit fails. Blood and Fat are the usual soft-part cleanup.
5. Embalm last, into a free pocket. A body holds at most six pocket items. Solution for Corpses adds white only, so do not put it on a body you mean to raise.

Burial cut versus zombie cut

Same actions, opposite endings. Every figure here is already on this page or the zombie guide. Verified (public source) on the Skin, Bones and Skull row means graveyardkeeper2.io’s quality table. Heart, Brain and Guts are not in that table.

On the worked 3 White / 2 Red body, Blood and Fat leave a burial at 3 White / 0 Red. The same cut leaves a zombie with no perk slots. Which technology reveals each organ is the tech tree unlock order. How the body arrived, when the wikis disagree, is corpse types.

Unlock & tools

1. Autopsy, Basic unlocks when you place the first body on the table (Wikily tech tree) — grants Autopsy Table I / Corpse Pallet I.
2. Craft a Butcher’s / Surgeon’s / Master Surgeon’s Kit at the Jewelry Table (Metallurgy mastery ~3–6 by tier). Prima and games.gg: operating without a kit is a guaranteed fail.
3. Raise Anatomy mastery (perk tree + food/sermon buffs). Wikily Autopsy Table ops run in ticks; enough successful ticks keep the organ, too few leave a Surgeon’s Error (−1 White / −1 Red) that also blocks resurrection.
4. Useful Anatomy perks (Wikily perk tree): Surgeon (starts ops with 2 successful ticks), Expert anatomist (+4 Anatomy at the table), Treasure Hunter (extra coin from organs).
5. Autopsy actions deplete Sanity — plan sessions around your meter (Prima / games.gg).

Recommended extraction order

1. Blood & Fat first — graveyardkeeper2.io lists six organs only (skin, bones, skull, heart, brain, guts). Early articles described a separate Dark Organ; that toggle was removed from the calculator. Wikily lists Blood and Fat each as 1 Red soft part; games.gg / Prima treat them as free (or early) Red cleanup. Always start here for burial; skip on zombie keepers if you need that Red.
2. Read each organ’s skull icons (Fextralife / Wikily Body parts) — same organ name can be White-heavy or Red-heavy by quality. Prima’s rule of thumb: extract Red unless the same organ carries more White.
3. Hard vitals (Brain / Heart / Guts) — need higher Anatomy (Wikily gold tiers reach mastery 13; Prima cites bronze-tier floors around Brain 8 / Heart 9 / Guts 11). games.gg also describes a “randomly destroy 2 skull values” narrative for these extracts; Wikily models the change as removing that organ’s carried skulls via tick success. Prefer Surgeon / Expert anatomist before gambling.
4. Flesh / Bones / Skin / Skull — for burial, don’t strip White-carrying parts for craft loot. games.gg’s fixed Flesh/Bone/Skin deltas are planner estimates; Wikily’s model is organ-carried skulls (see organs and corpse types).

Anatomy requirement by quality

From graveyardkeeper2.io — Corpses & Organs, checked 2026-10-14. These are the published floors for quality 1 / 2 / 3. At or above the requirement the result is always perfect. Below it you usually lose the organ, and a bad result replaces the slot with a Surgeon’s Error.

Heart, Brain and Guts are not in that requirement table. The Wikily floors below still list them; treat those rows as a second source. The same page’s worked chances, with no perks: Bones quality 1 at Anatomy 1 is about 4% perfect, 61% destroyed, 35% Surgeon’s Error. Skull quality 1 at Anatomy 1 is about 0% perfect.

Anatomy floors (Wikily)

Wikily’s Corpses and autopsy page lists an Anatomy requirement for every vital. Below that floor, each tick succeeds with chance Anatomy ÷ requirement; at or above the requirement, every tick succeeds. Too few successes leave a Surgeon’s Error (−1 Red / −1 White) that also blocks resurrection.

Bronze floors to remember: Heart 5, Brain 8, Guts 9. Gold Heart / Brain / Guts all sit at Anatomy 13 (Wikily). Prefer Surgeon / Expert anatomist before gambling on hard vitals.

When to stop

• Burial: White leads Red (you don’t need zero Red) and White rows can be covered by decorations.
• Zombie: Red matches the collar / perk plan; all six vitals intact; no Surgeon’s Error. Raising that body spends one Reanimation Liquid, which is not an embalming mix and does not add skulls. What the bottle is, the Clay + Alcohol + Salt recipe, and what it does at the table: Reanimation Liquid.
• Process promptly — games.gg warns long decay can add Green skulls that cannot be removed.
• Optional polish: embalming after organ work. Solution for Corpses adds White only; Injection for Corpses trades Red for White. Lye / Glue / Gold / Silver are not items.

Decide before you cut

The tables above say what each action costs. This is the order to use them when a body is already on the table. Skull numbers below are the planner’s worked 3 White / 2 Red example unless a line cites a published rule. Type the counts from your own corpse into the calculator before you trust a link.

1. Name the ending first. Burial wants White high and Red low, because grave score is the lower of (wreaths − Red) and White (White skulls). A zombie wants Red, because each Red skull is a perk slot, and White is unused (Zombie prep).
2. If a Surgeon’s Error is already in a slot, stop thinking about resurrection. graveyardkeeper2.io: −1 White, −1 Red, that slot cannot be used again, and the body cannot be raised. Open the warning in the calculator. Burial can continue; a zombie cannot.
3. Check Anatomy before any organ, not before pockets. Picking pockets never fails. Skin / Bones / Skull need Anatomy 1/3/6, 2/4/7 and 3/5/8 by quality. Below the line you usually lose the organ. Heart, Brain and Guts floors are only on the Wikily table above — treat those rows as a second source.
4. Burial: take Blood and Fat, leave Flesh. Each of Blood and Fat is 1 Red. Flesh is 1 White. On the 3/2 example that is 3 White / 0 Red versus 2 White / 0 Red if you also take Flesh.
5. Zombie: leave those pockets unless you can put the Red back. The same 3/2 body, untouched keeps 2 perk slots. Compare it with burial cleanup.
6. Embalm last, and only with a free pocket. Six pocket items is the cap, organs not counted. One checkbox in the calculator is one bottle. See which bottle.

Common mistakes

• Cutting under the Anatomy line to “see what happens.” A bad result is a Surgeon’s Error, and that body is out of the zombie pool for good.
• Using an old Lye / Glue / Gold / Silver shopping list. Those are not items. The bottles are Solution and Injection.
• Removing a “Dark Organ” that the wiki does not list. There are six organs. Read the skull icons on the organ you have.
• Trusting Skull +1 Red. That toggle is an unconfirmed GK1-style pattern. The calculator marks it. A White skull, removed cleanly, takes its White with it.
• Putting Solution for Corpses on a future zombie. It adds White only. The planner warns.
• Spending a seventh bottle. The table will not hold it. The planner skips it.
• Equating Net (W−R) with grave score. Net is a burial hint. The grave uses wreaths as well. A 4 White body under 3 wreaths still scores 3. Walkthrough on burial prep.

The days before the table is worth optimising are on first days.
