casualties-unknown.org is an independent, unofficial fan resource for Casualties: Unknown, the 2D subterranean medical survival simulator developed by Orsoniks / Oro Interactive and published by Orsoniks / Oro Interactive. We're not affiliated with, endorsed by, or compensated by Orsoniks / Oro Interactive, or any related entity.
Every fact on this site is drawn from Orsoniks / Oro Interactive's official site, official trailers, and professional press coverage of the reveal (linked throughout our pages). We don't use leaks, datamined content, or unverified claims as sourcing. Every image on this site is official Casualties: Unknown marketing material, downloaded from Orsoniks / Oro Interactive's own official site and rehosted on our own infrastructure with source and credit recorded for each asset — we never hotlink images from the official site or from other fan wikis.
Where something isn't officially confirmed, we say so plainly in the text rather than presenting speculation as fact. Where we do offer our own reading of a detail (for example, what a character's confirmed likes and dislikes might imply about their personality), it's clearly written as analysis, not as a claim about unreleased story content.
Primary official release facts, patch milestones, and store media for Casualties: Unknown are verified against the official Steam store page at store.steampowered.com (AppID 4576490) published by Orsoniks and Oro Interactive.
