Casualties: Unknown Water Purification and Light Guide

Boil groundwater in Casualties: Unknown using the documented canteen and campfire workflow, with light-source requirements and water-label warnings explained.

Quick answer

The release tutorial says to collect groundwater with a canteen and boil it using a campfire. A torch needs a flame source to relight, but the exact current gesture is unverified here. Read water descriptions carefully: a separate mildly radioactive liquid also displays the name Clean water.

Light first

What is confirmed about relighting?

The release Torch description says a flame source can relight it. The archived item index separately lists a Torch-plus-Heat-source repair entry. These support a relighting requirement, not an exact current gesture or universal Firestarter interaction. Check the current crafting entry or training instructions; this page does not promise a complete release torch-ignition walkthrough.

Clean water

The release Crafting Course explicitly tells you to boil groundwater into clean water. It names both prerequisites: a canteen to collect the liquid and a campfire to boil it. This workflow is also described in the crafting guide and directly confirmed by the release tutorial.

  1. Obtain or craft a canteen.
  2. Use it to collect groundwater.
  3. Prepare a campfire.
  4. Complete the groundwater-to-clean-water crafting step using the campfire.
  5. Inspect the resulting liquid and its description. Collection alone is not purification, and the display name Clean water alone does not establish that a liquid is free of radiation.

What should I prepare first?

The release Crafting Course names a canteen and campfire as the prerequisites for boiling groundwater. Prepare both using the recipes displayed in your build. This page does not give exact component quantities or INT thresholds from an older demo table.

Is groundwater already safe?

The release descriptions distinguish three liquids. Ordinary Clean water is safe; groundwater is mostly safe but slightly sickening; Dirty water is unsafe. There is an important naming exception: the separate radwater entry is also displayed as Clean water, but its description calls it mildly radioactive. Read the description rather than relying on the name alone. The older item index also shows two entries with this display name, but its internal item IDs are not mapped here to the release localization keys. Boiling therefore has a documented purpose even though groundwater is not described as uniformly lethal. These distinctions come from the release liquid descriptions.

Liquid labelRelease description
Ordinary Clean waterSafe, filtered water
Separate radioactive Clean water entryMildly radioactive despite the shared display name
GroundwaterMostly safe, slightly sickening
Dirty waterNot safe to drink

Why an older guide says boiling does not exist

The older survival page claims there is no boiling or purification action in demo 7.0.1. That conflicts with the archived demo crafting guide as well as the explicit release Crafting Course. For release guidance, follow the developer's canteen-and-campfire instruction; the older no-boiling statement is not applicable to that documented workflow. Sources: the conflicting older page, crafting guide and release text.

Build caveats

Release locale 1.0.1 confirms flame-source relighting and boiling with a canteen and campfire. Exact component recipes are not reproduced here, and the original cause of the contradictory demo descriptions is unresolved. No exact release ignition gesture, fuel quantity or hands-on crafting test is claimed.
