# Dune in Casualties Unknown
Dealing with a Dune trader

- 1 **Find the Dune in a life pod**They sell like any other Survivor

- 2 **Check your condition**A bite wounds you, so have dressings ready

- 3 **Accept a friendly bite**It raises reputation and lowers prices

- 4 **Bandage the bite**Then buy at the better price

_Built from recordings of Dune traders in Demo 7.0.1 and player tips. Numbers are not published._

**Short answer:** a Dune is a bat-like species in Casualties Unknown. In the demo they are Survivors who offer a **friendly bite** instead of haggling: it wounds you but raises your reputation and lowers prices. Players expect Dune to be a playable character in the full game. reported

`dune casualties unknown` has about 2,870 monthly searches (third-party estimate), mostly from people who have just met one in a life pod and been bitten. Playable stats arrived with the full game on 9 November 2026 and are not yet documented.

## What is a Dune in Casualties Unknown?

Dunes are one of the species you meet as Survivors. They trade from life pods, and a recording describes them as “the weird bat looking guy” with one very unusual feature: a bite you can ask for. confirmed Forum players talk about them as bite-happy and not very bright, and Dune dialogue is notably simpler than other Survivors. reported

They are also a running joke in the community. One long co-op recording has a player saying Dunes are the species they hate most, and the phrase “never let a dune bite you” comes up. confirmed

## What does the friendly bite do?

The bite is a trade action. Per a [video walkthrough](https://www.youtube.com/watch?v=VWists44i4U&t=1529s), it increases your reputation with the trader, and that raises your shopping discount. confirmed It also hurts, because you are being bitten.

| Effect | Detail | Status |
| --- | --- | --- |
| Reputation | Goes up | confirmed |
| Prices | Improve with reputation | confirmed |
| Your body | A wound that needs treating | confirmed |
| Limb loss | Players report a Dune can take a limb that is already ruined | reported |

Only Dune traders offer this. Another guide notes you can repeatedly haggle with traders **other than a Dune** to train Intelligence, because the Dune menu does not work the same way. confirmed

### Is a friendly bite worth it?

Take it when you have a good reason to buy, enough blood, and a dressing in your inventory. Skip it if you are already bleeding, since [blood loss](https://casualtieswiki.wiki/health/bleeding-and-blood/) is what kills most runs. A bite on an infected or low-skin limb is an extra risk, so check the [infection guide](https://casualtieswiki.wiki/health/infection-and-radiation/) first.

## Can a Dune remove a limb?

Players report it. In forum discussions about amputation, one player notes that the game normally needs a limb to be a lost cause before it lets you amputate, “unless you run into a dune who can bite it off for you”. reported We could not verify the exact conditions, so do not rely on it as a treatment. The [limb damage guide](https://casualtieswiki.wiki/health/limb-damage/) covers the normal way.

A mod even changes this behaviour: the Prosthetics mod’s notes say a Dune will not bite you if you have no normal limbs left. confirmed

## Is Dune playable in Casualties Unknown?

The developer confirmed three playable characters: the Experiment and two others. confirmed Each has its own stats and gimmicks, and each is unlocked by finishing a run with the previous one. confirmed The official posts do not name the species, but players expect Milky and Dune to fill those two slots, in that order. reported

In a video recorded before release, one player jokes that “playable Dune is not real”, which shows how much it was anticipated. confirmed As of the writing date we have not verified Dune’s stats. Check the [update log](https://casualtieswiki.wiki/update/) for when this page changes.

| Question | Answer | Status |
| --- | --- | --- |
| Third playable character? | Expected to be Dune | reported |
| How to unlock | Finish a run with the previous character | confirmed |
| In the demo? | As a trader only | confirmed |
| Stats | Not yet documented | unverified |

## How do you survive meeting a hostile Dune?

Survivors are not enemies by default. They turn on you when you threaten, attack or steal from them. If one is hostile, the same advice applies as for any fight: keep a wall between you and it, and do not fight in a position where one bad fall leaves you helpless. Melee trades can be costly, because all Survivors have far more health than the small creatures in early layers. reported The [enemies guide](https://casualtieswiki.wiki/layers/enemies-and-traps/) has the general rules.

## How do Casualties Unknown players use Dune traders?

The friendly bite is most useful when something in the Dune’s stock will save your run, such as a medical item or a backpack. A common pattern is to bite, buy, bandage, and leave. Sell lightweight, valuable items first so you need less discount. Circuit boards and spare dressings are worth carrying for this reason, as the [trading guide](https://casualtieswiki.wiki/characters/survivors-and-traders/) explains.
