At a glance: a corpse weighs 20, burns with 100ml of gasoline or on a campfire, and can be buried in a 2-tile grave. Corpses do not attract zombies. The real cost is sickness, and you only start gaining noticeable sickness at 0.001 per tick — the second of three moodle levels.
The myth that makes players waste fuel
Almost every new player burns every corpse they see, because everyone repeats the same warning: rotting bodies draw hordes. The wiki directly contradicts it. On the Corpse page it is listed as one of the common misconceptions about corpses — zombies can be found feasting on corpses, but decomposing bodies do not lure them. What bodies around your base actually cause is corpse sickness.
That distinction changes the decision completely. Burning corpses to “avoid attracting a horde” is solving a problem that does not exist, and it costs you 100ml of gasoline per body while doing it. Gasoline is the same resource you need for generators and vehicles.
The three ways to dispose of a body
The wiki lists three methods, and they are not equivalent in cost:
| Method | Cost | Notes |
|---|---|---|
| Gasoline | 100ml per corpse | Fastest, but burns a resource you cannot easily replace early |
| Campfire | Fuel for the fire | No gasoline needed; needs a fire source you are already running |
| Grave | 2 tiles of space | Costs no fuel; a furniture tile used for burying bodies |
Picking between them is mostly about what is scarce. Before you have a gas can and a vehicle, the campfire or the grave is the cheaper habit. Once gasoline is plentiful, burning on the spot is simply faster.
What corpse sickness actually does
The mechanic behind bodies is the noxious smell moodle (moodle ID NoxiousSmell). It is a negative moodle that indicates the player is being affected by an environmental smell, and it drives how fast you gain sickness.
The wiki breaks it into three levels, and the thresholds are what matter:
| Moodle level | Sickness gain per tick | What the wiki says |
|---|---|---|
| Bad Smell | greater than 0, below 0.001 | “Mostly a warning.” |
| Awful Odor | between 0.001 and 0.002 | Player starts gaining noticeable sickness and may become sick |
| Overwhelming Stench | greater than 0.002 | “A vile stink makes you feel ill.” |
The first three levels come from proximity to rotting corpses, mainly zombie corpses. The final stage is treated as a different effect and can only be reached by entering a building with an active generator — so if you are outside and hit the top moodle, the generator is your problem, not the bodies.
Reading this back into a decision
Put the two facts together and the rule becomes simple:
- Bad Smell is not an emergency. Below 0.001 per tick the wiki calls it mostly a warning. You can keep looting.
- Awful Odor is your cue to act. That is the point where you start gaining noticeable sickness and may become sick.
- Overwhelming Stench means you waited too long — or that you are standing in a building with a running generator.
So the efficient habit is not “burn everything on sight.” It is: loot first, watch the moodle, and only spend fuel once it reaches Awful Odor. If you have a gas mask or an item with the SCBA tag, you can skip the whole problem, because the wiki states noxious smell can be avoided by wearing one.
Where corpses come from
Corpses as items spawn naturally during world generation as dead survivors, or as the result of the player killing a zombie or an animal. Dead survivors turn up as part of a survivor house or survivor story, and very rarely in the trunk of a vehicle. Corpses can be found with a range of items such as clothing or weapons, which is a good reason to check them before you burn them.
One number worth knowing for inventory planning: a corpse weighs 20. You cannot quietly stack a dozen of them into a backpack.
Animal corpses are a different problem entirely
The disposal methods are the same, but the weights are not. A human corpse weighs 20, while the animal corpses listed on the wiki run far heavier — and some are heavier than anything you could reasonably carry.
| Corpse | Weight |
|---|---|
| Human corpse | 20 |
| Dead White-Tailed Doe / Buck | 110–200 |
| Dead American Landrace Boar | 115–350 |
| Dead East Friesian Ram | 80–200 |
| Dead Angus Cow | 360–950 |
| Dead Angus Bull | 360–1300 |
A bull at up to 1300 is roughly 65 times the weight of the human corpse you were already struggling with at 20. In practice that means large animal carcasses are not a “pick it up and burn it” job — deal with them where they drop, or leave them well away from where you sleep.
A note on version
The wiki flags the Corpse page as last updated for build 42.16.0 and the noxious smell page for 42.13.1, against a current stable build of 42.21.0, so exact tuning may have moved. The structural facts — that bodies do not lure zombies, the three moodle levels, and the 100ml of gasoline — have been stable across those builds.
For the wider early-game picture, see the Project Zomboid beginner guide and the survival guide. Base hygiene sits alongside the base-building guide, and if bodies are piling up because you are clearing a street, the combat guide and best weapons tier list cover the killing side.
