About the Casualties: Unknown Wiki

Short answer

This is an unofficial, fan-made guide to Casualties: Unknown. It is not made by, endorsed by or affiliated with Orsoniks or Oro Interactive. Facts come from official Steam posts first, then the community wiki's code-checked mechanics, the wikily.gg 1.0 database and player reports, and every page lists its sources.

Applies to Release 1.0 (Nov 9, 2026) Sources checked

What this site is

A focused field guide for players who are mid-run and need an answer fast: what is wrong with my character, how do I fix it, what does this layer need, what can I craft. It does not try to list every item; for that, use the community wiki or wikily.gg database.

How facts are sourced

Each source on a page carries a badge:

  • Official Steam store page, developer posts and patch notes, Steam achievement stats, the press kit. Highest trust.
  • Community wiki The Scav Prototype / Casualties: Unknown wiki, whose editors read values from the game code. Most numbers were last checked on demo builds 5.1 to 7.0, so we label them that way.
  • Database wikily.gg, which publishes 1.0 data for layers, run settings, characters and endings.
  • Players Steam forum threads and mod pages. Used for practical advice and to flag reports, not for exact numbers.
  • Press Press coverage, for context.

When the 1.0 patch notes contradict an older number, the patch notes win and the page says so. Layers 6 to 11 are marked "early info" until more 1.0 data is confirmed. Each page shows the build it applies to and when its sources were checked.

Credits and images

Casualties: Unknown is developed by Orsoniks and published by Oro Interactive. Screenshots are official images from the Steam store page, used in small numbers to illustrate the guide, and credited where shown. The game logo and key art are not used. The site's body diagram, icons, layer chart and preview cards are original artwork. Game names and content belong to their owners.

If you are the developer or publisher and want an image removed or credited differently, tell us and it will be changed promptly.

Corrections

Nobody can verify every number in a game this detailed on day 2 of release. If something is wrong for 1.0, tell us which page and what you saw in game, and the page will be updated with a new checked date. The updates log records site and game changes.
